You can connect Avaya branch gateways to an Avaya server directly or through other gateways. Gateways are the stackable and modular hardware elements of the communication system and deliver connectivity to different endpoint and trunk types. Gateways provide data, voice, fax, video, and messaging capabilities to the network. Bearer networks are connections between gateways that allow the passage of media types. Control networks are connections between the server and the gateways for call-control signaling.

Avaya branch gateways support bearer and signaling traffic routed between packet-switched and circuit-switched networks. Avaya branch gateways provide flexible deployment options, including Internet Protocol (IP) environments and blended environments such as IP and Time Division Multiplexing (TDM).

Avaya branch gateways support the following features:

• Interoperability with standard data networks

• Stackable, modular, and configurable component solutions

• Redundant equipments and capabilities

• Distributed networking
