Configuration of IP Telephony nodes using Element Manager Page 377 of 910
IP Line Description, Installation and Maintenance
g. Subnet mask: The subnet mask for the IP address of the trap
destination must always be configured as 255.255.255.255.
h. Click Add to enter the IP address for another trap destination.
Add destination SNMP Manager IP addresses for the following:
• local or remote OTM server
• PPP IP address configured in the router on the ELAN subnet
for the remote-support OTM PC
• SNMP manager for remote alarm monitoring
Note 1: Up to eight SNMP trap destinations can be defined.
Note 2: A net route or host route through the Management (ELAN)

End of Procedure
Configuring community name strings
The SNMP community name strings control access to the IP Telephony node.
Element Manager uses the community name strings to refresh the Voice
Gateway Media Card status and to control the transmitting and retrieving of
configuration data files for database synchronization.
WARNING
Always configure the trap destination subnet mask as
255.255.255.255. Do not enter the actual value of the
subnet mask on the interface of the SNMP trap
destination. Doing so can cause misrouting of RTP media
and signaling, leading to no speech path between the IP
Phones and the Voice Gateway Media Cards or failure of
the IP Phones to register with the LTPS.
