Mysterious PRI message

[geirendre]

Keep getting this message on a Opt11 about 8-10
times pr hour:

PRI207 DCH: 80 DATA: 0029

System is 2 Opt.11 Rls with 20.22 on both switches.
Switches linked with a TIE-trunk.
Also have a DID to the CO from the "main" switch.
Message only displayed on the "main" switch.
LCNT in LD60 shows no bit-errors or slip's
on the loops.
Funny thing is, there is no DCH 80 defined on the switch!

Any suggestions ?

Build up a DCH 80 and then remove it? Just a shot in the dark.

it wont let you build a dch80, only 0-15

 

[ArchibaldJCox]

this is true

Geirendre,
What prints out when you stat your D-channels?
LD 96
STAT DCH <enter>

 

[geirendre]

When I do a STAT DCH in LD 96 all I get is my 2 active DCH's, like:

DCH 14 : OPER EST ACTV AUTO DES : CO
DCH 15 : OPER EST ACTV AUTO DES : TIE

That's it.
I'm pretty sure the PRI207 message comes from the CO's side of the CO-trunk, but how can I verifie this without physically disconnecting any of the 2 trunks?

I have seen these errors on my switch before & still from time to time. Someone once told me that they're protocol errors & usually coming from the carrier side. PRI errors are additonal "features" that Nortel doesn't support, features that are coming from your CO that AT&T type switches use. I'm not sure if there is a patch for that, something to look into...

i would look at the enl msgi x on the d back to the co. see if that ref's a far end dch 80. another shot in the dark. can you build a bdch to switch to, to see if the trouble moves?
