Core Architecture of Avaya Aura

To effectively administer Communication Manager, you must first understand its place within the broader Avaya Aura® architecture. Avaya Aura® is not a single product but a suite of integrated applications that work together to provide a comprehensive unified communications solution. The Avaya 3100 exam expects you to have a foundational knowledge of how these key components interact. The central call processing engine is Avaya Aura® Communication Manager (CM). This is the brain of the system, responsible for call routing, feature control, and overall telephony logic. It is the component you will spend the most time administering. Communication Manager is supported by Avaya Aura® System Manager (SMGR), which is the centralized, web-based management platform for the entire Aura® suite. From SMGR, you can manage users, licenses, and system configurations for multiple Aura® components. Another key component is Avaya Aura® Session Manager (SM). Session Manager is a powerful SIP (Session Initiation Protocol) routing core. It provides the architectural flexibility to integrate a wide variety of SIP endpoints, trunks, and applications into the Aura® environment. Finally, Media Gateways, such as the G450 or G650, provide the physical interface between the IP-based Aura® network and the traditional telecommunications world, such as connections to the Public Switched Telephone Network (PSTN) via T1/E1 circuits.

Understanding the Role of Communication Manager

Avaya Aura® Communication Manager is the evolution of Avaya's legendary line of Private Branch Exchange (PBX) systems. While it still performs the core functions of a traditional PBX, such as connecting internal calls and routing external calls, it is a much more powerful and flexible software-based solution. It serves as the feature and application server for a wide range of user endpoints, including digital phones, IP phones, soft clients, and mobile devices. Communication Manager is responsible for the entire lifecycle of a call. When a user picks up their phone and dials a number, it is CM that analyzes the dialed digits, consults the dial plan, and determines how to route the call. It also provides the rich set of hundreds of telephony features that users rely on, such as call forwarding, call coverage, conference calling, and hunt groups. It is the engine that makes everything work. The software can be deployed on a variety of platforms, from dedicated Avaya servers to virtualized environments running on VMware. This deployment flexibility is a key advantage of the modern architecture. The Avaya 3100 exam will test your ability to administer the features and functions of this core component, regardless of its underlying deployment model.

Key Management Interfaces for the Administrator

An administrator interacts with Communication Manager primarily through two interfaces. A solid understanding of both is absolutely essential for the Avaya 3100 exam. The first, and more modern, interface is Avaya Aura® System Manager (SMGR). SMGR provides a centralized, secure, web-based graphical user interface for managing all the components in the Aura® platform. For Communication Manager, SMGR is used to manage users, endpoints, and many system-wide configurations in a more user-friendly and integrated manner. The second, and more traditional, interface is Avaya Site Administration (ASA). ASA is a Windows-based client application that provides a terminal emulation interface to the Communication Manager's native command-line administration shell, often referred to as the System Administration Terminal (SAT). Many experienced Avaya administrators prefer the speed and power of the SAT for performing detailed configuration tasks. It provides access to every single command and feature within Communication Manager. While System Manager is becoming the primary interface for many day-to-day tasks, a proficient administrator must be comfortable working in both environments. Some advanced features and troubleshooting commands are only accessible through the SAT. The Avaya 3100 exam will contain questions that assume knowledge of both the graphical SMGR interface and the command-line structure of the ASA/SAT.

Navigating the Path to Certification

The journey to passing the Avaya 3100 exam and achieving the Avaya Aura® Communication Manager Administration certification is a challenging but achievable goal. It requires a combination of theoretical knowledge, practical skills, and a deep understanding of the system's logic. This 6-part series is designed to provide a structured and comprehensive overview of the exam topics to guide your studies. In the subsequent articles, we will take a deep dive into the specific administrative domains. We will start by exploring the management interfaces in more detail and then move on to the initial system configuration, including the critical dial plan setup. We will then cover the day-to-day tasks of managing users, endpoints, and trunks. Following that, we will explore the powerful call handling features, such as call coverage and vectoring. To be successful, you should supplement your theoretical study with as much hands-on practice as possible. Working in a live or lab environment is the best way to solidify your understanding of the configuration commands and the relationships between the different system components. By following this series and dedicating time to practical application, you will build the confidence and competence needed to pass the Avaya 3100 exam and become a certified support specialist.

A Deep Dive into System Manager (SMGR)

Avaya Aura® System Manager (SMGR) is the cornerstone of modern Aura® administration. It provides a single, centralized point of control for the entire suite of Aura® applications, including Communication Manager. For the Avaya 3100 exam, you must understand the role and basic navigation of SMGR. It is a web-based platform that provides a graphical user interface (GUI) for performing administrative tasks, which can be more intuitive for new administrators than the traditional command-line interface. One of the primary functions of SMGR is user and endpoint management. It allows you to create and manage user profiles, which can be associated with multiple communication devices, such as a desk phone, a soft client, and a mobile device. This user-centric approach is a key feature of the modern Aura® architecture. SMGR is also the central repository for system-wide data, such as dial plan information and security settings, which it then synchronizes to the other elements like Communication Manager. Beyond user management, SMGR is used for managing system inventory, licenses, and security. It provides a consolidated view of all the Aura® elements in your network and their health status. While many detailed, low-level configuration tasks are still often performed directly on Communication Manager, SMGR is the starting point for most administrative workflows in a modern, fully-integrated Aura® environment.

Mastering Avaya Site Administration (ASA)

While System Manager provides a modern web interface, the traditional and still very powerful tool for direct Communication Manager administration is Avaya Site Administration (ASA). ASA is a Windows client that provides a terminal emulator for connecting to the System Administration Terminal (SAT). A deep proficiency in using the SAT is absolutely mandatory for passing the Avaya 3100 exam. The SAT is a command-line interface that provides access to every configurable feature of the system. The SAT uses a consistent command structure. The primary commands are add, change, display, list, and remove. For example, to view the configuration of a specific user's phone, you would use the command display station 1234. To modify it, you would use change station 1234. The list command is used to see a summary of all configured objects of a certain type, such as list station. The interface is organized into a series of forms, with each form containing a set of fields that correspond to the different configuration parameters. Navigating these forms and knowing which fields to modify to achieve a specific outcome is the core skill of a CM administrator. ASA provides helpful features like command history and scripting to improve efficiency, but a solid knowledge of the key commands and forms is essential.

Understanding the Core System Configuration

Before you begin configuring users and features, you must be familiar with the core system-wide parameters that govern the overall behavior of the Communication Manager. These settings are typically configured once during the initial system installation but may need to be modified later. A key form for this is the change system-parameters features form. This multi-page form contains hundreds of settings that control how telephony features work across the entire system. For example, this is where you will find settings related to the number of digits in an extension, the default time zone for the system, and the enabling or disabling of specific features like call forwarding and automatic callback. While the Avaya 3100 exam will not expect you to know every single field on this form, you should be familiar with the major sections and know where to look for common system-wide settings. Other important system-level forms include change system-parameters maintenance, which controls alarm settings, and change system-parameters ip-options, which defines the settings for IP network connectivity. A good administrator knows that a change to one of these system-level parameters can have a widespread impact, so they should be modified with care and a full understanding of their function.

Configuring Dial Plan and Numbering Formats

The dial plan is the heart of any telephony system. It is the set of rules that Communication Manager uses to interpret the digits that a user dials and to determine how to route the call. A proper understanding of the dial plan analysis table is one of the most critical topics for the Avaya 3100 exam. The display dialplan analysis form is where you define the length of your extensions, the feature access codes (e.g., *72 for call forwarding), and the codes for accessing external trunks. For routing calls between different locations in a multi-site network, you will use either the Uniform Dial Plan (UDP) or Automatic Alternate Routing (AAR). UDP provides a simplified dialing experience where users can dial a simple extension to reach someone at a remote site. AAR is a more powerful feature that allows you to define a set of routing patterns to reach a specific destination. For routing calls to the public telephone network (PSTN), you will use Automatic Route Selection (ARS). The ARS table is a digit analysis table that is used to determine which trunk group to use for an outbound call based on the number that was dialed. For example, you can configure ARS to route local calls over your local PSTN trunks and long-distance calls over a less expensive SIP trunk.

Managing Locations and Network Regions

In a multi-site IP telephony deployment, it is crucial to manage the network resources effectively. Communication Manager uses two key constructs for this: locations and network regions. A location is used to group devices that are in the same physical site, such as an office building or a campus. The primary purpose of locations is for bandwidth management and call admission control (CAC). You can define the amount of bandwidth that is available for calls between different locations, and CM will prevent new calls from being established if the available bandwidth is exceeded. A network region is a logical grouping of devices that share the same network characteristics. The network region configuration is where you define critical IP parameters, such as the codec set that should be used for calls within that region or between that region and another. The codec set defines the audio compression algorithm that will be used, which has a direct impact on both the voice quality and the amount of bandwidth consumed by the call. Network regions are also used to specify the IP addresses of the media resources, such as the media gateways and conference bridges, that are available to the devices in that region. A proper configuration of locations and network regions is essential for ensuring high-quality voice and for preventing network congestion in a large IP telephony deployment.

Practical System Navigation for the Avaya 3100 Exam

Success on the Avaya 3100 exam, and in a real-world administrative role, depends heavily on your ability to navigate the system efficiently to find and change information. When working in the SAT, there are several techniques that can speed up your work. The go command allows you to jump directly to a specific page on a multi-page form. For example, change station 1234, followed by go 3, will take you directly to page 3 of the station form. The F1 key is your best friend in the SAT. It provides context-sensitive help for whatever field your cursor is currently in. This is an excellent way to learn the purpose of the thousands of different fields in the system. The F5 key is another useful tool; it provides a list of the valid entries for a given field. Another powerful navigation technique is the use of abbreviations. You do not need to type out the full command change station; you can simply use cha sta. Over time, you will learn the common abbreviations for the forms you use most often. By combining these navigation techniques, you can perform administrative tasks much more quickly and efficiently, which is a key skill of an experienced administrator.

Creating and Managing User Stations

The most common day-to-day task for a Communication Manager administrator is managing user stations, or extensions. Every user's telephone is represented in the system as a "station." The add station and change station commands are the most frequently used commands in the System Administration Terminal (SAT). A deep familiarity with the station form is absolutely critical for the Avaya 3100 exam. When you add a new station, you must define several key pieces of information. The "Type" field specifies the model of the telephone, such as "9611G" for an IP phone or "2420" for a digital phone. The "Port" field defines the physical or logical connection point for the device. For a digital phone, this will be a specific port on a circuit pack in a media gateway. For an IP phone, it will be a logical port assignment. Other crucial fields include the "Name" of the user, the "Security Code" for voicemail access and feature control, and the "COR" (Class of Restriction) and "COS" (Class of Service), which control the user's calling permissions and feature access. The station form is also where you will program the functions of the various buttons on the user's telephone, a topic we will cover in more detail.

Configuring Digital and IP Telephones

Communication Manager supports a wide variety of endpoint types, and an administrator must understand the fundamental differences in how they are configured. Digital telephones, such as the 2400 and 9500 series, are "dumb" terminals. All their feature logic and configuration is stored directly within Communication Manager. They connect via a dedicated digital line circuit card in a media gateway. Their administration is straightforward, as everything is done on the station form. IP telephones, such as the 96x1 series, are much more intelligent devices. While their primary configuration is still managed on the CM station form, they also require an IP network infrastructure to function. They boot up and use the Dynamic Host Configuration Protocol (DHCP) to obtain an IP address. DHCP also provides them with the address of a file server, which is typically a TFTP or HTTP server. From this file server, the IP phone downloads its firmware and a critical configuration file, often called the 46xxsettings.txt file. This settings file contains a wide range of parameters that control the phone's behavior, such as the address of the Communication Manager server to register with, the network settings, and the user interface options. A basic understanding of this IP phone startup process is essential knowledge for the Avaya 3100 exam.

Understanding Trunk Groups and Signaling

While stations provide internal communication, trunk groups are the connections that link the Communication Manager to the outside world. A trunk group is a collection of channels, or call paths, that connect to another telecommunications system. This could be a connection to the Public Switched Telephone Network (PSTN), a connection to another PBX system, or a connection to a SIP-based service provider. Each trunk group is configured to use a specific signaling protocol. Signaling is the language that the two systems use to set up, control, and tear down calls. For traditional connections to the PSTN, the most common signaling protocol is ISDN-PRI (Integrated Services Digital Network - Primary Rate Interface). ISDN-PRI provides a reliable, digital signaling method for carrying voice calls and caller ID information. For modern, IP-based connectivity, the dominant protocol is the Session Initiation Protocol, or SIP. SIP is a flexible and powerful protocol that is used to establish real-time sessions, including voice and video calls, over an IP network. The Avaya 3100 exam will expect you to be familiar with the concepts of both ISDN and SIP trunking.

Configuring an ISDN-PRI Trunk Group

The configuration of an ISDN-PRI trunk group involves several related forms in the SAT. The process begins with the configuration of the signaling group. The add signaling-group form is where you define the parameters for the D-channel, which is the dedicated channel on the PRI circuit that carries all the signaling information. You will specify the port location of the T1 or E1 circuit pack that the PRI is connected to. Once the signaling group is defined, you can create the trunk group itself using the add trunk-group command. On the trunk group form, you will give the group a number and a name. You will then specify the "Group Type" as "isdn" and associate it with the signaling group you just created. The trunk group form is also where you will define the specific channels, or "members," of the trunk group. An ISDN-PRI in North America (T1) has 23 bearer channels for voice calls. Other important settings on the trunk group form include the country protocol and the digit handling rules. A correct and thorough configuration of both the signaling group and the trunk group is essential for establishing a reliable connection to the PSTN.

Administering SIP Trunks for Modern Connectivity

SIP trunking is the modern standard for connecting a communication system to a service provider. It offers greater flexibility and often lower costs than traditional ISDN circuits. The configuration of a SIP trunk in Communication Manager is conceptually similar to an ISDN trunk but uses different forms and terminology. The process again starts with the add signaling-group command. For a SIP trunk, the signaling group defines the IP addresses of the far-end SIP proxy server (often called a Session Border Controller, or SBC) that CM will communicate with. You will also define the transport protocol, which is typically UDP or TCP. After the signaling group is configured, you create the trunk group using the add trunk-group command, this time specifying the "Group Type" as "sip." The SIP trunk group form is where you associate the trunk with the SIP signaling group. Unlike an ISDN trunk, a SIP trunk's capacity is not limited by the number of physical channels but rather by the number of simultaneous call sessions that are allowed by the service provider's license. The ability to configure both legacy ISDN and modern SIP trunks is a key skill for a versatile administrator.

Using Templates and Bulk Import for Efficiency

In a large organization, creating hundreds or even thousands of new stations one by one using the add station command would be an incredibly time-consuming and error-prone task. To address this, both System Manager and Avaya Site Administration provide tools for bulk administration. This is an important practical concept for any administrator and is relevant to the Avaya 3100 exam. System Manager provides a powerful templating feature. An administrator can create a template for a specific type of user, such as a "Sales User" or a "Contact Center Agent." This template can pre-populate most of the required fields on the station form, including the button assignments, Class of Service, and Class of Restriction. When a new user of that type needs to be added, the administrator can simply apply the template, and only the unique information, like the name and extension, needs to be entered. For even larger jobs, both SMGR and ASA support bulk import capabilities. An administrator can prepare a spreadsheet (typically in a CSV format) with the data for all the new stations. They can then use the import utility to have the system create all the stations automatically from the data in the file. These tools can save an enormous amount of time and ensure consistency in the configuration.

Introduction to Call Coverage and Forwarding

A fundamental requirement of any business telephone system is to handle calls effectively when a user is unable to answer their phone. Avaya Communication Manager provides a rich set of features for this purpose, and a deep understanding of them is a core requirement for the Avaya 3100 exam. The two most basic of these features are call forwarding and call coverage. Call forwarding is a user-activated feature. A user can go to their telephone and program it to forward all their incoming calls to another number, such as their mobile phone or a colleague's extension. This is known as "Call Forwarding All Calls." This feature is simple and controlled entirely by the end-user. Call coverage, on the other hand, is a more powerful, administrator-programmed feature. It defines a specific path that a call should follow if the user does not answer their phone after a certain number of rings or if their line is busy. This path can include multiple destinations and provides a much more structured and controlled way to ensure that important calls are never missed. Most of the administrative work for call handling revolves around the configuration of call coverage.

Configuring Call Coverage Paths

The heart of the call coverage feature is the coverage path. A coverage path is a numbered list of up to six coverage points that a call will be sent to in a sequential order. These paths are configured using the change coverage path command in the System Administration Terminal (SAT). Each coverage path is given a unique number. For each point in the path, you can specify a destination and the number of rings to wait before moving to the next point. A coverage point can be another user's extension, a hunt group, or, most commonly, the user's voicemail system. For example, a simple coverage path might have a first point that sends the call to an administrative assistant after 3 rings. If the assistant does not answer, the second point might then send the call to voicemail. Once a coverage path is created, it is assigned to a user via their station form. The change station form has a "Coverage Path" field where you enter the number of the path that should be used for that user. This powerful feature ensures that calls are automatically rerouted according to a predefined business rule, providing a much more robust solution than simple call forwarding.

Using Coverage Answer Groups

In some scenarios, a user, such as an executive, may have a group of assistants who are all responsible for answering their calls. Instead of creating a complex coverage path that lists each assistant individually, a more efficient solution is to use a Coverage Answer Group. A coverage answer group is a special type of hunt group that is designed specifically for this purpose. To configure this, you first create a new group using the add coverage-answer-group command. You then add the extensions of the assistants who will be members of this group. Once the group is created, you can use it as a destination in a coverage path. On the executive's coverage path, you would set the first coverage point to be the coverage answer group number. When a call to the executive is not answered, it will be sent to this group. Communication Manager will then alert all the members of the group simultaneously, and the first person to answer will get the call. This provides a simple and effective way to manage call answering for a team of assistants. This is a common business requirement and a practical scenario for the Avaya 3100 exam.

Understanding Bridged Call Appearances

Bridged call appearances, often simply called "bridging," is another powerful feature for handling calls in a manager-assistant scenario. A bridged appearance allows an assistant to have a button on their phone that is a direct representation of a line appearance on their manager's phone. This provides a much tighter integration than call coverage. When a call comes in on the manager's line, the bridged appearance button on the assistant's phone will also light up and ring. The assistant can then press this button to answer the call directly. This feature also allows the assistant to see the status of the manager's line. If the manager is on a call, the light next to the bridged appearance button will be on, so the assistant knows not to transfer a call to them. Configuration of a bridged appearance is done on the station form. On the manager's station form, you will define one of their call appearances as a bridged call. Then, on the assistant's station form, you will program a button with the feature "brdg-appr" and specify the manager's extension. This feature is extremely popular and a key part of the feature set tested on the Avaya 3100 exam.

Administering Hunt Groups for Team-Based Answering

For departments that receive a high volume of calls, such as a sales team or a customer support desk, a hunt group is the standard solution. A hunt group is a single extension number that routes incoming calls to a predefined group of members. This allows a customer to call one number and have their call answered by the next available person in the department. Hunt groups are configured using the add hunt-group command. On the hunt group form, you will define the members of the group and, most importantly, the call distribution method. There are several different methods to choose from. "Circular" mode, or round-robin, sends calls to the members in a sequential order. "UCD-MIA" (Uniform Call Distribution - Most Idle Agent) sends the call to the agent who has been idle the longest, which is great for evenly distributing the workload. "EAD-MIA" (Expert Agent Distribution) is a more advanced option used in call centers. Hunt groups also have their own coverage path. If all the members of the hunt group are busy or do not answer, the call can be sent to another destination, such as a backup group or a general voicemail box. The ability to configure and manage hunt groups is a fundamental skill for any Communication Manager administrator.

Practical Scenarios for the Avaya 3100 Exam

The Avaya 3100 exam will often present you with questions that are framed as a business requirement or a problem scenario. Your task will be to select the Avaya feature or configuration that best solves the problem. It is therefore crucial that you not only know how to configure these features but also when to use them. For example, a question might describe a scenario where a manager wants their assistant to be able to answer their calls, but only after their own phone has rung three times. This would be a perfect use case for a call coverage path. If, however, the manager wants their assistant to be able to see their lines and answer them immediately, a bridged call appearance would be the better solution. Similarly, if a company wants to set up a general number for their IT help desk that will ring multiple technicians, a hunt group is the correct feature to use. By thinking through these practical applications, you will be much better prepared to answer the scenario-based questions on the Avaya 3100 exam and to design effective solutions in a real-world environment.

Introduction to Call Vectoring for Automated Attendants

While hunt groups are excellent for routing calls to a team of live agents, many organizations need a more sophisticated way to handle their incoming calls. They want to be able to play announcements, provide callers with a menu of options, and route calls based on the time of day or other conditions. This is the role of call vectoring, which is Avaya's powerful scripting engine for creating automated call flows. A deep understanding of vectoring is a major component of the Avaya 3100 exam. The two key components of call vectoring are Vector Directory Numbers (VDNs) and Vectors. A VDN is a special type of extension number that does not ring a physical phone. Instead, its sole purpose is to receive an incoming call and immediately pass it to a specific vector for processing. A vector is a series of programmed steps, like a simple software program, that tells Communication Manager exactly how to handle the call. Together, VDNs and vectors are used to build powerful applications like auto attendants ("Press 1 for Sales, Press 2 for Support"), interactive voice response (IVR) systems, and sophisticated call queuing and routing for contact centers. The ability to create and manage these automated call flows is a key skill for an advanced administrator.

Creating Vector Directory Numbers (VDNs)

The entry point for any call vectoring application is the Vector Directory Number, or VDN. A VDN is configured using the add vdn command in the System Administration Terminal (SAT). The VDN form is relatively simple, but it contains several important fields that you must understand for the Avaya 3100 exam. The most important field is the "Vector Number" field. This is where you specify which vector the VDN should send the call to. Another key field is the "Name" field, which should be used to give a clear and descriptive name to the VDN, such as "Main Auto Attendant" or "Sales Queue." The VDN form also allows you to override certain system settings for calls that arrive on this specific VDN. For example, you can assign a specific Class of Restriction (COR) to the VDN to control its calling permissions. You can also configure the VDN to collect digits from the caller before passing the call to the vector, or you can assign specific announcements to be played. The VDN acts as the front door, performing some initial classification and treatment of the call before handing it off to the more powerful vector for the detailed call processing logic.

Programming Basic Vector Steps

A vector is a sequence of up to 32 steps that are executed in order. Each step consists of a command that tells Communication Manager what to do with the call at that point in the flow. The Avaya 3100 exam will expect you to be familiar with the most common and important vector commands. The wait-time command is one of the most basic; it tells the system to wait for a certain number of seconds before proceeding to the next step. This is often used to play a few seconds of ringing before an announcement. The announcement command is used to play a pre-recorded audio file to the caller. This is used for greetings, informational messages, or menu options. The queue-to command is used to place the call in a queue for a specific team of agents, which is typically a hunt group or a contact center skill. While the call is in the queue, it will hear music on hold or other announcements until an agent becomes available. The route-to number command is used to send the call to a specific destination, such as an extension, a hunt group, or an external phone number. By combining these basic commands in a logical sequence, you can build a simple but effective automated call flow.

Managing Announcements and Music on Hold

A key part of any automated attendant or call queuing system is the use of audio announcements and music on hold. Communication Manager provides a flexible system for managing these audio sources. Announcements are typically stored on dedicated announcement circuit packs within a media gateway or on a separate media server. Each announcement is assigned a unique extension number. To use an announcement in a vector, you simply reference its extension number in the announcement command. An administrator is responsible for recording and loading these announcements onto the system. This can be done by calling into a special administration number and recording the announcement over the phone, or by uploading a pre-recorded .wav file. Music on hold is managed in a similar way. You can connect a physical audio source, such as a CD player or a streaming device, to an analog port on a media gateway. This audio source is then assigned a music on hold extension number. In a vector, the wait-time command can be configured to play music while the caller is waiting in a queue. A proper setup of these audio resources is essential for a professional-sounding call flow.

Using Variables and Conditional Steps in Vectors

To create truly interactive and dynamic call flows, you need to be able to use variables and conditional logic in your vectors. This is a more advanced topic, but a foundational understanding is important for the Avaya 3100 exam. The collect digits command is used to prompt the caller to enter digits from their keypad. For example, "Please enter your 5-digit account number." The digits that the caller enters are then stored in a special variable within the vector. Once you have collected these digits, you can use a conditional command, goto step if, to route the call based on the value that was entered. For example, goto step 10 if digits = 12345. This command allows you to create branching logic in your vector. This is the foundation of any menu system ("Press 1 for Sales, Press 2 for Support"). The vector will collect one digit and then use a series of goto step if commands to route the call to the appropriate part of the vector based on the digit that was pressed. Vectors also support a range of built-in variables that can be used for conditional routing. For example, there are variables for the time of day, the day of the week, and the number of agents currently staffed in a skill. This allows you to create very intelligent call flows, such as routing calls to a different destination after business hours.

Analyzing Vector Performance with Reports

Once you have a VDN and vector in service, it is important to be able to monitor its performance to see how calls are being handled. Communication Manager includes a powerful built-in reporting engine called the Basic Call Management System, or BCMS. BCMS is designed to provide detailed statistics on the performance of hunt groups, VDNs, and vectors. BCMS provides a set of standard reports that can be run directly from the SAT. For a VDN, you can run a report that shows you how many calls came in, how many were answered, how many were abandoned, and the average time it took to answer them. This is critical information for understanding the caller experience and for identifying any potential problems in your call flow. For example, if you see a high number of abandoned calls on a particular VDN, it might indicate that the announcements are too long, the queue times are excessive, or there is a problem in the vector logic that is causing callers to hang up. By regularly reviewing these BCMS reports, an administrator can proactively identify and resolve issues, ensuring that the automated call handling system is operating efficiently and effectively.

Performing System Backups and Restores

One of the most critical responsibilities of a Communication Manager administrator is to perform regular backups of the system. A reliable backup is the ultimate safety net, allowing you to restore the system's configuration in the event of a catastrophic failure or a major misconfiguration. A deep understanding of the backup and restore process is an essential skill and a key topic for the Avaya 3100 exam. Communication Manager supports several different types of backups. A full backup captures the entire system configuration, including the user translations, the dial plan, and the system parameters. An incremental backup only captures the changes that have been made since the last full backup. A common strategy is to perform a full backup on a weekly basis and incremental backups on a daily basis. The backups can be sent to a variety of destinations. A common method is to use a secure file transfer protocol, such as SFTP or FTP/S, to send the backup files to a dedicated server on the network. The system also supports backing up to a USB drive or a local hard drive on the server. The entire backup process can and should be scheduled to run automatically. An administrator must know how to configure this schedule and how to manually initiate a backup or a restore when needed.

Managing Alarms and System Logs

Proactive system management involves regularly monitoring the health of the Communication Manager. The system provides a comprehensive alarming and logging framework to alert the administrator to any potential problems. The primary command for viewing active issues is display alarms. This command will show a list of all the current alarms on the system, categorized by their severity level: Major, Minor, or Warning. Each alarm has a specific code and a description that provides information about the nature of the problem. For example, a major alarm might indicate the failure of a critical circuit pack, while a minor alarm might indicate that a trunk is out of service. An administrator must know how to interpret these alarms and take the appropriate corrective action. In addition to the real-time alarms, the system also maintains a detailed error log. The display errors command can be used to view a historical log of all the error events that have occurred on the system. This log is an invaluable tool for troubleshooting intermittent problems or for performing a root cause analysis after an outage. Regular monitoring of these alarms and logs is a key part of maintaining a healthy and reliable system.

Implementing Class of Service (COS) and Class of Restriction (COR)

Securing a communication system involves more than just preventing unauthorized access; it also involves controlling the features and calling permissions of the legitimate users. Communication Manager uses two powerful features for this: Class of Service (COS) and Class of Restriction (COR). A thorough understanding of the difference and application of these two features is a frequent topic on the Avaya 3100 exam. Class of Service, or COS, is used to control a user's access to the hundreds of different telephony features that are available on the system. By creating different COS profiles, an administrator can define different sets of features for different groups of users. For example, you might create a basic COS for general office users that grants them standard features, and a more advanced COS for executives that grants them additional features like priority calling. Class of Restriction, or COR, is used to control a user's calling permissions. It determines where a user is allowed to call. You can create different CORs to, for example, allow some users to only make internal calls, allow other users to make local and national calls, and allow a select group of users to make expensive international calls. The COR is a powerful tool for controlling toll fraud and managing telecommunication costs.

Administering Security and User Passwords

A Communication Manager administrator is responsible for maintaining the security of the system itself. This begins with managing the login accounts that are used for administration. It is a critical best practice to create unique login accounts for each administrator and to avoid sharing the root or super-user account. The system allows for the creation of different login profiles with varying levels of access to the system commands. Another key aspect of security is managing the passwords and security codes for the end-users. Each station has a security code that is used to access voicemail and to activate certain features like call forwarding from a remote location. An administrator is responsible for setting the initial security codes and for assisting users who have forgotten their code. The system also provides a number of security settings that can be configured to enhance the overall security posture. This includes setting password complexity rules for administrative logins, configuring session timeouts, and managing the access security gateway, which is a list of IP addresses that are permitted to access the system for administration. These security practices are a key part of the knowledge required for the Avaya 3100 exam.

Each component has specific configuration requirements and management procedures that exam candidates must understand thoroughly.

Communication Manager's Processing Capabilities

Communication Manager processes calls using a sophisticated state machine that tracks each call from initiation through completion. When a user lifts a handset or initiates a call through a softphone, Communication Manager allocates resources and begins collecting dialed digits. The system analyzes the dial pattern against its routing tables to determine how to complete the call, whether to an internal extension, an external trunk, or a feature access code. This analysis occurs in milliseconds, ensuring that users experience no noticeable delay in call setup.

The call processing engine maintains detailed state information for every active call, tracking the calling party, called party, connection time, and features in use. This information enables features like call transfer, conference, and call forwarding to function seamlessly. Communication Manager continuously monitors call quality metrics and can adjust codec selection or media path routing to optimize the user experience. The system's ability to process calls efficiently while managing thousands of simultaneous connections demonstrates the sophisticated design of its processing architecture.

Advanced call processing features rely on Communication Manager's ability to execute complex logic based on multiple variables. The system evaluates caller privileges, time schedules, trunk availability, and feature activations to determine the appropriate action for each call. It can queue calls when resources are unavailable, provide busy or overflow treatment, and generate detailed call detail records for billing and analysis purposes. The processing engine's flexibility allows administrators to implement custom call flows that match specific business requirements while maintaining system stability and performance.

Integration with Network Infrastructure

Communication Manager's integration with the underlying network infrastructure is critical to its operation and performance. The system relies on properly configured network switches, routers, and firewalls to deliver voice packets with minimal latency and jitter. Quality of Service mechanisms must be implemented throughout the network to prioritize voice traffic over less time-sensitive data. Communication Manager works with network equipment to tag voice packets appropriately and ensure they receive preferential treatment during periods of network congestion.

The system supports multiple networking protocols and can operate in various network topologies, from simple flat networks to complex multi-tiered architectures. VLAN configurations often separate voice traffic from data traffic, providing additional security and performance benefits. Communication Manager interfaces with DHCP servers to automatically provision IP endpoints with the correct network settings, including TFTP server addresses for firmware downloads and configuration files. The system can also integrate with network time protocol servers to ensure accurate timestamps for call records and system logs.

Network security considerations play a significant role in Communication Manager deployments, with the system supporting encryption for both signaling and media streams. Firewalls must be configured to allow the necessary traffic while blocking potential threats. Communication Manager can operate behind network address translation devices, though this requires careful configuration to ensure proper media flow. The system's network requirements extend to bandwidth planning, with administrators needing to calculate the aggregate bandwidth needed for simultaneous calls across WAN links. Understanding these network integration points is essential for successful system deployment and troubleshooting.

Licensing and Capacity Planning

Communication Manager operates under a licensing model that defines the system's capacity and available features. License files specify the maximum number of users, stations, trunks, and concurrent calls the system can support. Additional licenses enable advanced features like conferencing, mobility, and contact center capabilities. Administrators must carefully track license usage to ensure compliance and avoid service disruptions when limits are reached. The licensing system includes grace periods that allow temporary overuse during transitions or emergency situations.

Capacity planning requires analyzing current usage patterns and projecting future growth to ensure adequate system resources. Factors to consider include the number of users, peak call volumes, trunk requirements, and feature usage. Communication Manager provides detailed reports and real-time monitoring tools that help administrators understand resource utilization. The system can be scaled vertically by adding more processing power and memory to existing servers, or horizontally by distributing load across multiple server instances.

Planning must also account for redundancy and disaster recovery requirements. Many organizations deploy duplicate Communication Manager servers in different geographic locations to ensure business continuity. The active server handles all call processing while the standby server remains synchronized and ready to take over in case of failure. Licensing considerations extend to these redundant systems, with special licenses available for disaster recovery scenarios. Proper capacity planning ensures that the system can handle both normal operations and peak demand periods while maintaining performance standards and user satisfaction.
