27.1.1 What is Survivable Remote MGC?
Survivable Remote MGC (SR-MGC) is placed on remote office to manage the call of IP terminals and SIP ter-
minals and trunk call to/from PSTN via MG in case of network failure (
) or the Telephony Server break-
down on the main office. In normal state, SR-MGC operates in stand-by mode under monitoring of the
Telephony Server. Once the Telephony Server cannot accept the registration of SIP/IP terminals in remote of-
fice, the operation is switched over to the SR-MGC. When the Telephony Server recovers, the SR-MGC returns
to stand-by mode. SR-MGC consists of two units of equipment, SR T20 and SR S20. SR-MGC can handle both
SIP terminals and IP terminals (
For Service Conditions for SR-MGC, refer to “Survivable Remote MGC [S-141]” of Data Programming Man-
ual - Business. For Service Conditions peculiar to SR-MGC with Location Diversity, refer to “Location Diver-
sity [L-55]” of Data Programming Manual - Business.
Note:
Two-Unit SR-MGC is only available for FP85-106 S3 or earlier.

Note 1:
“Network failure” must include failure of communication between SR-MGC and LAN1 port of the Te-
lephony Server in order to switch operation over to SR-MGC because network failure is diagnosed by
communication failure between SR-MGC and LAN1 port. This condition needs to be considered espe-
cially when you use MG(PRI) in Proprietary Protocol mode which uses LAN2 of the Telephony Server
as the interface. For more information relating to this condition, refer to “Survivable Remote MGC [S-
141]” of the Data Programming Manual - Business.
Note 2:
Each “SIP terminal” and “IP terminal” is a generic term representing a group of terminals. Refer to
“TERMS IN THIS MANUAL” at the top of this manual if you want to know specific terminals that these
terms represent.
