Using Media Gateway 1000B

The Media Gateway 1000B (MG 1000B) provides a means of extending
Avaya Communication Server 1000 Release 4.5 features to one or more
remotely located branch offices using the Branch Office feature. A branch
office is a remote location in the network where IP Deskphones, PSTN
access, and TDM IP Deskphones are located. Contact your system
administrator to see if these functions are available for your use.
The Media Gateway 1000B (MG 1000B) IP Deskphone can operate in
Normal or Local Mode.
Normal Mode
The IP Deskphone registers with the Main Office and receives IP
Deskphone services from the Main Office. At any time while using Normal
Mode, you can check Local Mode functionality (make and receive calls)
by enabling Local Mode and returning to Normal Mode. After testing, you
can return to Normal Mode (see
page 189) or wait for 10 minutes.
Local Mode
If the WAN connection goes down, the IP Deskphone loses
communication with the Main Office TPS. It then registers with the
MG 1000B and receives IP Deskphone services from the MG 1000B.
