Page 484 of 910 Configuration of IP Telephony nodes using OTM 2.2
553-3001-365 Standard 4.00 August 2005
2Enter the following ELAN network interface settings:
a. Call Processor IP: Enter the Call Processor ELAN network interface
IP Address (Active ELNK).
Note 1: Ensure that the Call Processor ELAN network interface IP
address that is configured on the Ports tab is not the same IP address as
the ELAN network interface IP address of the Voice Gateway Media Card.
Each IP address must be unique.
Note 2: The Call Processor ELAN network interface IP address must
correspond to the Active ELNK IP address configured in LD 117. It must
be in the same subnet as the ELAN subnet for the IP Telephony node.
b. Survival Cabinet IP: If applicable, enter the Survivable Cabinet
ELAN network interface IP address (Active ELNK). This is the IP
address that is configured for survivability. The survivable Cabinet IP
is enabled only for Small Systems and CS 1000S systems.
Note: For Small Systems or CS 1000S, this field is disabled unless at
least one cabinet has been defined as a survival cabinet of the main
system in OTM Navigator. There is only one survival cabinet IP address
for each node. The survival cabinet is equipped with sufficient trunk cards
and Voice Gateway Media Cards. In case of Call Server equipment
failure, it provides a large degree of survivability for IP Phone users.
c. Signaling port: The default value is 15000. This field is read-only.
d. Broadcast port: The default value is 15001. This field is read-only.
3Enter the following TLAN settings:
a. Signaling port:
b. Voice port: Change the Voice port only as instructed by the IP
network administrator to improve QoS for the IP Phones. For
example, if RTP Header compression is used to reduce voice
bandwidth on narrow-band WAN links, then TLAN voice port range
must be set to 16384 or higher. The exact range will be provided by
the system administrator.
Note: The TLAN Voice port range is 1024 to 65535. The default Voice
ports are 5200-5295.
