Section 6 Fail-Over - NEC Univerge SV9100 Manual

S 6 F
ECTION AIL
With NetLink, a connection to the Primary System may be lost (disconnected or
powered down) from the TCP/IP connection. When this occurs, there could be a loss
of control at all Secondary Systems.
The Fail-Over feature works when NetLink has lost connection to the Primary System
for longer than the defined keep-alive timer. It finds one of the Secondary Systems to
take over the Primary Systems database so that NetLink can still work. The
networked communication servers reboot (this takes approximately 30 seconds), and
when they come back up are linked to the new Primary System.
10-30
If Program 51-16-01 is set to 1, set the time to replicate the program data
(0000~2359).
51-16-03 : NetLink System Data Replication Mode Setting – System Data

Replication Interval Setting
If Program 51-16-01 is set to 2, set the interval time between replicating the
program data (15-1440 minutes).
51-16-04 : NetLink System Data Replication Mode Setting – Replication Time

Stamp
This program displays the last time the program data was replicated. This is
automatically updated when the replication occurs. This option is view-only.
51-16-05 : NetLink System Data Replication Mode Setting – System Data

Replication Wait Time
When a NetLink network is created, this option determines the time the SV9100
waits until replication is started (1~86400 seconds).
51-16-06 : NetLink System Data Replication Mode Setting – System Data

Replication Interval
Set the time to start replication to the next node after replication has completed
to one node (1~86400 seconds).
51-17-01 : Registrar Port

This is the SIP registrar port of each system when NetLink is used. Open range
is 0-65535, default is 5080.
51-17-02 : Subscribe Session Port

This is the SIP subscribe session port number for each system when NetLink is
used. Open range is 0-65535, default is 5081.
51-18-01 : NetLink Fail-Over Limit

When tear-down of network is repeated more than the specified times, NetLink
is operated in stand-alone. Input range is 0, 2~10 (0 = No limit). Default is 0.
51-19 : Net-Link IP Trunk(SIP) Calling Party Number Setup for Extension

This program assigns transmission of Calling Party Number from PRG21-19 for
each secondary system. The transmission applies for every extension.
