Nortel Networks 1120 User Manual

The Media Gateway 1000B (MG 1000B) provides a means of extending 
CS 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 Phones, PSTN access, and TDM IP 
Phones are located. Contact your system administrator to see if these 
functions are available for your use.

The Media Gateway 1000B (MG 1000B) IP Phone can operate in Normal 
or Local Mode.

The IP Phone registers with the Main Office and receives IP Phone 
services from the Main Office. At any time during 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 “Using Resume Normal Mode” on page 132) or by 
waiting for 10 minutes.
