Product glossary

3270 interface

A link between one or more IVR systems and a host mainframe. In the system documentation, the 3270 interface specifically means the link between one or more system machines and an IBM host mainframe.

Access Security Gateway

An authentication tool that secures logins. ASG uses an authentication protocol to confirm the validity of users and reduce the opportunity for unauthorized access. Successful authentication is accomplished when ASG-enabled devices communicate with compatible keys. The authentication transaction consists of a challenge (essentially a random number), followed by the receipt of a response entered by the user. Interception of the challenge or the response does not compromise the security of the system, as the relevance of the authentication token used to perform the challenge and response is limited to the current challenge and response exchange.


A response that the platform (using the alarm and remote maintenance feature) takes to one or more events, depending on its configuration. For a major alarm, for example, the platform speaker could sound, contacts could close to sound a local alarm, and a panic call to INADS could be initiated. Each of these responses is considered an action.

action list

The set of configured actions taken in response to an event and its severity level.

adjunct products

Products (for example, the Adjunct/Switch Application Interface) that the system administers via cut-through access to the inherent management capabilities of the product itself. This is in opposition to the ability of the system to administer the switch directly.

Adjunct/Switch Application Interface

An optional feature package that provides an Integrated Services Digital Network (ISDN)-based interface between Avaya PBXs and adjunct processors.

alarm log

A list of alarms that represent all of the active or resolved problems on a system. The alarm log can be accessed either locally or remotely.


A system process that responds to patterns of events logged by the logdaemon process.


A message the system plays to the caller to provide information. The caller is not asked to give a response.


Software that executes logical control over what happens during a call. Applications are compiled from TAS language scripts or VoiceXML objects that are written by application developers, who typically use Avaya IVR Designer. C language implementations of IRAPI may also be used as applications.

Each application can lie dormant on the platform until an IRAPI command is executed to start the application. The application then integrates with others using IRAPI functions and sharing common external functions. The system supports third party packages from various vendors.

application administration

application installation

A two-step process in which the system invokes the TSM script assembler for the specific application name and moves files to the appropriate directories.

Avaya IVR Designer

A development environment that allows you to design applications on a Windows-based PC, using a graphical user interface (GUI) that you can customize. This tool allows you to develop applications by specifying the details of interaction between the system and its callers. Avaya IVR Designer features standard Windows operations, with right-click menus and enhanced cut, copy, and paste capabilities. It can be used to create TAS and VoiceXML applications.

call data handler process

A software process that accumulates generic call statistics and application events.

call flow

See transaction.


The party who calls for a service, gets connected to the system, and interacts with it. Because the system can also make outbound calls for service, the caller can also be the person who responds to those outbound calls.

Communication channels are distinguished by having one or more hardware, software, or network requirements that are unique. Separate channels may share the same type of content (text, audio, video, image) or immediacy (live or delayed). Examples of communication channels include PSTN Voice, VoIP, Chat, Email, FAX, Document, Instant Messaging, and Voice Mail.

Converse Data Return (conv_data)

An Avaya IVR Designer external function or a Script Builder external action that supports the call vectoring (routing) feature by enabling the switch to retain control of vector processing in the system environment.
