TLAN. If a Voice Gateway Media Card becomes the primary (Leader)
during an election, it assigns itself the Node IP address.
b. Management LAN gateway IP: Enter the Management LAN (ELAN)
gateway IP address in dotted decimal format. This is the IP address
of the gateway of the subnet to which the Voice Gateway Media Card
belongs. This is the IP address of the router interface on the ELAN
subnet, if present. If there is no Management LAN gateway, enter
0.0.0.0.
c. Management LAN subnet mask: Enter the Management LAN
(ELAN) network interface subnet mask address in dotted decimal
format. This is the subnet mask that is used, along with the ELAN
network interface IP address, to identify the subnet to which the
Voice Gateway Media Card belongs.
d. Voice LAN subnet mask: Enter the Voice LAN (TLAN) subnet mask
address in dotted decimal format. This is the subnet mask used along
with the TLAN IP address, to identify the subnet to which the Voice
Gateway Media Card belongs.
7Click the Configuration tab and continue with Procedure 52 on
page 469.
End of Procedure
CAUTION
Nortel recommends that the TLAN network interface IP
address of the Voice Gateway Media Card(s) and the
TLAN Node IP address not be the same IP address; that
is, each IP address should be unique. (Note: the TLAN
network interface IP address of the Voice Gateway
Media Card(s) is configured on the Configuration tab.)
If a card’s TLAN network interface IP address and the
Node IP address are the same, then it is necessary to
reboot the Voice Gateway Media Card every time there
is a temporary loss of ELAN or TLAN subnet
connectivity.
