Wistron Corporation IPNTYS05N Manual De Usuario

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.

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 

) or wait for 10 minutes.

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.
