Avaya 03-300430 User Manual

A network region is a logical grouping of IP endpoints (including IP stations, IP trunks, and 
media gateways) sharing the same transmission characteristics and/or VoIP and signaling 
resources, such as a Media Processor board or a C-LAN. The Network-Region Connect 
(NR-CONN) MO monitors VoIP connectivity between network regions and raises a:

●

Warning alarm for a single failure.

This alarm is in response to one failed background ping test between IP endpoints in 
separate network regions. This test is part of the background 

●

Minor alarm for multiple failures.

Once a single failure is detected, Test #1417 is re-executed between different IP endpoints 
in the same pair of network regions. If the test still fails between these network regions:

- Maintenance software marks the connectivity between them as “failed.”

- Communication Manager denies every attempted call between them.

As a background operation during each 2-minute interval, Test #1417 checks the translated 
connections between 50 pairs of network regions until every translated connection has been 
tested, and then repeats. (The Communication Manager translation table’s maximum capacity 
for network-region connections is 31,250. Testing every possible connection would require 625 
2-minute test intervals during about 21 hours.)

●

Use display failed-ip-network-region to display pairs of network regions with 

failed connectivity.   In descending order of severity, this command lists up to 100 network 
regions with the most severely broken connectivity.

●

Use status ip-network-region to see the status of connections from a particular 

network region.

●

As an on-demand operation, test failed-ip-network-region retests every 

network-region connection marked as “failed.” Those connections that:

- Pass are returned to service.

- Fail are remarked as “failed” and remain on the list of bad connections.
