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:

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
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:
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.)

Repair strategies
●
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.
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.
