In Alarm Browser go to View Set Filter. Here we can filter the alarms of

Tamil Nadu Circle based on Date/Time, Node, Severity etc.

What to do when Node is indicated as Down

Ping the router to check the current status of links.

If it is pinging wait for NNM screen to get refreshed. After refresh

(refresh time is 15min) the links /router should turn back to normal.

If Router is not pinging Perform the following steps at Exchange end.

a. Conduct the Loop test for E1 Links from Transmission room

b. If Loop test is ok, Do Ping test again.

c. If Ping test fails execute “Trace route “ from your PC and

note IP Add where it is dropping.

d. If IP Add is dropping at 172.26.x.x series Please contact

NIB/MPLS and Parallely inform CDR Datacenter.
