Contact Closure; Fax, Modem, And Tty Over Ip; Service Level Agreement Monitor - Avaya G450 Overview And Specification

Branch Gateway services
MM714B media module by connecting the module trunk port 5 to line port 4. You can also connect
two external 808A ETR panels to the Branch Gateway front panel port. Each 808A Emergency
Transfer Panel provides emergency trunk bypass or power-fail transfer for up to five incoming
trunk loops to five analog phones. It also maintains connections when switching from Emergency
Transfer mode to normal operation.

Contact Closure

The Contact Closure feature is a controllable relay providing dry contacts for various applications.
To implement Contact Closure, you must connect an Avaya Partner Contact Closure adjunct box
to the CCA port on the Branch Gateway chassis. The adjunct box provides two contact closures
that can be operated in either a "normally closed" or "normally open" state. Contact closures can
control peripheral devices, for example, devices that automatically lock or unlock doors, or voice
recording units. You can configure the CCA port so that the connected devices are controlled by
an endpoint device, such as a phone. For example, a user can unlock a door by entering a
sequence of digits on a phone keypad.

Fax, modem, and TTY over IP

Branch Gateway supports fax, modem, and TTY over IP.

Service Level Agreement Monitor

Service Level Agreement (SLA) Monitor is an integrated set of tools designed to obtain high audio
and video performance in a converged network. SLA Monitor communicates with IP telephony
components and other sources through a web-based server application. With the data gathered by
SLA Monitor, you can check the network contribution to the performance of audio and video
applications.
SLA Monitor performs the following functions:
• Corrects Differentiated Services issues.
• Handles rogue applications.
• Provides real-time visibility to live sessions.
The SLA Monitor agent is a component of SLA Monitor. The agent participates in enterprise end-
to‐end monitoring and troubleshooting of various types of network issues that affect IP telephony.
The SLA Monitor agent can trace packets from source to destination. The SLA Monitor agent can
also monitor Differentiated Services markings at each hop as the packets travel through the
network.
G450 Branch Gateway acts as a SLA Monitor agent.
The SLA Monitor server collects router-flow data, as well as data from SLA Monitor agents, to
provide a clear picture of how the network and media elements contribute to end-to-end quality.
