IP Office PRI Trunk goes Out of Service during calls

[kuchulane]

hi all

we are using Avaya IP Office 406 V2 with a PRI 30 card . software version 5.0(24).

From the last week calls are dropped in the middle and System status shows "trunk out of service".
From the system status, I can see following

Service Alarm:
8KHz clock source chaned. previous source was internal.

Trunk Alarm:
Truck out of service.
2 yellow alarms.
2 Transmit/receive slips
495 E-Bit Error

Please help in solving this issue as I dont have much telecom or IP office knowledge.

Many Thanks

Line provider issue, they will probably deny it but 9 out of 10 it is

Thanks for the reply amriddle.

Is there any way I can prove this to BT.Our line provider is BT(using an ISDN 30 NTE52D box)

Thanks

You don't really need to prove it to BT, when reporting faults to BT the first thing they will say is "system fault" they always do it's like a reflex action, you need to insist they action further. Next they will say they have tested the line and it tests fine, sound convincing ...except they can only test their downstream connection the the NTE they cannot test the link from NTE to the system (which is usually at fault). Insist they send an engineer out and they may well threaten to bill if it's a system fault, just accept that and say you still want someone onsite. The reason they try so hard to avoid sending an engineer is since they outsourced all engineering tasks to BT Openreach (effectivly a seperate company) they get charged for call outs/site visits .

I am not saying it can't be the system but very rarely it is with this type of fault, to prove otherwise you need another system to test with or Trend/ISDN emulator and they aint cheap and BT still will not believe you anyway

in system status check the 24hr summary.
you will see loads of errors.
Tel BT you are seeing e-bit errors, framing errors & what ever else may be happening. give them times & figures & they will realize that you do actually have some idea.

do not be frightened by the usual "possible charges" line.

it should not take long to get this resolved.
