Can only have one DCH on CS1000M Rls 5.0

[geirendre]

A few months back we upgraded our Opt.11c from Rls4.5 to Rls5.0
after this we are not able to get our two DCH's to work simultaneously.
I can only program one DCH and get it up and running.
If i program DCH 8 first on port 1 of the SDI/DCH-card,
it works fine, DCH established.
When I then try to add the second DCH (DCH 9) on port 3 i get a

ERR5279 DCH:9  CAUSE:3

BTW:
ERR5279
Application state was disabled, while the port on the MSDL card was
enabled.

If I out both DCH's and try to add DCH 9 first, it works.
But when I then try to add DCH 8 as the second DCH I get
the same ERR5279, and it will not establish.

I have tried with a different (new) DCHI-card, new cables, even two separate cards for each DCH.
Moved cards to different loops and cabinets, same problem everywere.

Any help greatly appreciated

Forgot to mention that this is D-channels used for VNS
between our main site and two branch offices.
At the branch offices we have Opt11's both on Rls. 4.5

The D-channels initialy worked after the upgrade at our
main site, until the PBX's at one of our branch offices
had an restart. After the restart (cold restart) the
D-channel refused to come up again, and thats when the
problem started.

To me this sounds like a software issue, but we haven't
been able to find any patch related to such issues.

we upgraded a system from 3.0 to 5.0 and we have 4 T1's on the system all with Dchannels. I'm not sure why. Have your vendor check this.

I would check the SLT in ld 22 to start.

Thanks janaya.
We have 2 PRI's and 2 TIE's all with their "integrated" Dchannels working fine.

The problem is with Dchannels from a SDI/DCH-card connected
with serial cabels to Cisco routers that routes the Dchannel
through our WAN to the other sites.
ADAN DCH 8
CTYP DCHI
PORT 1 (or 3)
USER VNS

And our SLT shows plenty off spare DCH licenses...

Check your patching. There wa an issue with VNS on Rls5. Basically the circuit would not come up.

Check
MPLR25183 VNS: Cannot Enable VNS DCH on MSDL

-> dulfo666: Yes I'm avare of the problem with establishing VNS in Rls.5.0. We had to postpone our upgrade for 6 moths while Nortel worked out the issue.

-> johnpoole: Anything else would surprice me ;-)

-> dulfo666: Nice, I'l have our vendor check on that when I get back to the mainsite by the end of the week.
Sounds promissing, but isn't MSDL only used on large systems not Opt11's?

Thanks a lot for the feedback and suggestion.

Since I left my former job, I no longer have access to Nortels site to check for patches. Just helping our vendor working this out. They seem a little lost....
