SR-MGC
bit5: SR-MGC
→
MGC connectivity check by PING
0/1=SR-MGC → MGC connectivity check by PING is disabled/enabled.
If the Telephony Server (MGC) is configured redundant, the decision as to which the Telephony Server
(MGC) (MGC#0 or MGC#1) data will be copied depends on the following data assignment.
bit7: Method of specifying the Telephony Server (MGC) when copying the office data.
0/1=MGC#0
Note 3
/Active-side MGC
Note 4
Note 1:
This is available when Mode in the CMNT command is set to 2.
Note 2:
Assign 1 for enabling the rescue by SR-MGC when a failure occurred only on LAN1 while MG(PRI) in
Proprietary Protocol mode is operated on LAN2 port. The following conditions are required to enable
this data setting:
• LAN1/LAN2 of the Telephony Server is assigned to different segments (IP addresses)
• LOC-IDs are assigned per SR-MGC
Assign 0 if the above conditions cannot be met. Otherwise, MG(PRI) in Proprietary Protocol mode
may become unavailable due to the system conditions, such as during construction periods.
Note 3:
When MGC#0 is down, MGC#1 is specified.
Note 4:
Even if the data files in MGC#0 and MGC#1 are identical, the different time stamps may be written
into the data files because Standby-side MGC data is backed up after the backup of the Active-side
MGC data. Therefore, the office data copy after the system changeover is available for the data files
with different time stamps even if the data files are not updated.
Index 847: Assign a time to execute forceful changeover against terminals.
bit0-3: Timer Counter for forceful switchover
0: 70 minutes (default)
1-E: time assigned at intervals of 5 minutes
F: Not available
bit4: Alarm is sent before forceful switchover is executed
0/1=Not alarmed/Alarmed per minute
Index 850: Assign SR-MGC Health Check cycle.
00 HEX. = 30 seconds (default)
01 ~ 0F HEX. = 15 seconds
10~ FE HEX. = 16 ~ 254 seconds
FF HEX. = Stop sending Health Check packet from the Telephony Server (MGC) to SR-MGC
Note:
When changing the default value (30 seconds), be sure to assign an identical value (SR-MGC Health
Check cycle) to all the nodes.
Index 851: Assign Time-out to receive Health Check response.
