Survivable Remote Gateway 50 Configuration Guide
Normal and local mode overview: CS 1000 details
Normal mode
Telephones and clients that are connected to the SRG but are registered with the main office are in
Normal Mode. The main office provides centralized call processing and extensive telephony
features and applications for the SRG IP Phones. These telephones are registered to the main
office TPS and are controlled by the Call Server at the main office. Survivable IP users connected
through the SRG50 receive the features, key layout, and tones of the main office Call Server. This
provides feature and application transparency between the branch office and the main office.
Local mode
An IP Phone at the SRG may be in Local Mode for two different reasons;
1
IP Phone may have just booted up
2
IP Phone cannot communicate to the Main Office because of a WAN failure or a failure of the
Main Office components.
3
IP Phone is in Test Local Mode.
Devices that are physically located with the SRG and are controlled by the SRG system are said to
be in Local Mode. These devices consist of analog telephones, analog devices such as, fax, and
may include IP Phones. Normally IP Phones are registered to the main office, in Normal Mode,
however when the IP Phone cannot reach the main office, it reverts to Local Mode.

That is, the CS 1000 Zone ID is entered on the SRG50 in the Zone ID
field, and the ZDP is entered on the SRG50 in the VPNI field (refer to
“Bandwidth Management” on page 38
).
