553-3001-365 Standard 4.00 August 2005
2Enter the following Management LAN (ELAN) configuration settings:
a. Call Server IP address: This is the IP address of the Call Server on
the ELAN subnet. Enter the Call Server ELAN network interface
IP address (Active ELNK).
Note: The Call Server ELAN network interface IP address must
correspond to the Active ELNK IP address configured in LD 117. The IP
address must be in the same subnet as the ELAN subnet for the IP Line
node.
b. Survivable Media Gateway IP address: This address is configured
for survivability. It is the IP address of the Survivable CS 1000S
Media Gateway on the ELAN subnet.
Note 1: The Survivable CS 1000S Media Gateway IP address must
correspond to the Active ELNK IP address. If configured, all Voice
Gateway Media Cards in the same node should be in the same Survivable
Cabinet.
Note 2: The Survivable Media Gateway associated with the Primary
Signaling Server IP Telephony node is called the Alternate Call Server. It
is normally located in the same equipment rack with the Call Server and
Signaling Server; therefore, it is normally connected to the same ELAN
subnet as the Call Server and the Primary Signaling Server IP Telephony
node. The Alternate Call Server Media Gateway should be equipped with
sufficient trunk cards, Voice Gateway Media Cards, and centralized
CallPilot, so that it provides a large degree of survivability in case of
Call Server equipment failure for IP Phone users who normally register
through the Signaling Server.
Refer to Communication Server 1000S: Planning and Engineering
(553-3031-120) and Communication Server 1000S: Installation and
Configuration (553-3031-210) for more information about survivability.
c. Signaling port: The default value is 15000. The range is 1024 to
65535.
d. Broadcast port: The default value is 15001. The range is 1024 to
65535.
