IP Line administration using OTM 2.2 Page 671 of 910
IP Line Description, Installation and Maintenance
If the IP addresses of a single card have changed, the card must be restarted
for the changes to take effect. See “Restart a Voice Gateway Media Card” on
page 671. However, if IP addresses that affect the entire node have been
changed, then all cards in the node must be restarted. See “Restart all Voice
Gateway Media Cards” on page 672.
Restart a Voice Gateway Media Card
If the IP address of a Voice Gateway Media Card has changed, restart that
card only. Follow the steps in Procedure 97.
Procedure 97
Restarting a Voice Gateway Media Card
1To prevent interruption to the speech path, log into LD 32. Type the DISI
command.
This command disables the voice gateway channels when they become
idle. DISI removes the call traffic but does not remove the IP Phones that
are registered on that Voice Gateway Media Card. The Graceful TPS
Disable command disiTPS does that.
2Type disiTPS at the card’s IPL> prompt to disable the LTPS service on
the Voice Gateway Media Card.
This Graceful TPS Disable command prevents new IP Phones from
registering on the card. All IP Phones registered on the card are
re-directed to another Voice Gateway Media Card when the IP Phone
becomes idle.
After the command is entered, an idle IP Phone is supposed to be
updated with the Watchdog reset message. However, the LTPS sends a
soft reset message to the IP Phone, redirecting it to the Connect Server.
The disabled LTPS does not accept new registrations, so the IP Phone
must register with another LTPS in the node. Eventually, as all of the IP
Phones on the LTPS become idle, they are registered with other LTPSs.
The Voice Gateway Media Card can then be restarted with no impact to
any users.
