PRI Outage

Hey Everyone,

I have a PRI that is currently down. Here is what my controller shows

0/0/1 is down.

Applique type is Channelized T1

Cablelength is long gain36 0db

Transmitter is sending remote alarm.

Receiver is getting AIS.

alarm-trigger is not set

Soaking time: 3, Clearance time: 10

AIS State:Clear LOS State:Clear LOF State:Clear

Version info Firmware: 20070725, FPGA: 13, spm_count = 0

Framing is ESF, Line Code is B8ZS, Clock Source is Line.

CRC Threshold is 320. Reported from firmware is 320.

Data in current interval (623 seconds elapsed):

0 Line Code Violations, 0 Path Code Violations

0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 623 Unavail Secs

Total Data (last 24 hours)

0 Line Code Violations, 11 Path Code Violations,

5 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 4 Degraded Mins,

9 Errored Secs, 2 Bursty Err Secs, 0 Severely Err Secs, 7085 Unavail Secs

I found this on internet so I opened a ticket with my provider. "Another message you might receive is "receiver is getting AIS." This means the receiver is getting an alarm indication signal (blue alarm). This is a framed or unframed all-ones signal in both SF and ESF formats transmitted to maintain transmission continuity. This is typically seen when the far-end CSU has lost its terminal side equipment.".But I wanted to see if anyone else has seen this with a PRI. If so, am I going down the right path with opening a ticket with my provider? Also, I noticed when I went to the physical device (VWIC2-2MFT-T1/E1) and looked at the T1 cards both T1's were reporting a (orange/yellow) alarm, but when I check the second controller it doesn't shows errors and shows "Active" "Multi Frame established" is this second alarm caused by the Vwic2 card and can be ignored?

Re: PRI Outage

You are right in reporting a fault to telco.

Disregard lights and only look at show controllers output.
