Stutter dial tone over a Premisys Channel Bank (FXO/FXS)

[nessman]

Dumb question...

Resolved an issue with some dead OPX's to a remote site that's carried over the customer's microwave system. Premisys channel banks on either end of the microwave hops, with an FXO card on the PBX side, and and FXS card on the remote side.

We have 8 OPX's going out to this site, only 3 were working, and 5 were down. Difference was the working ones had a steady dial tone, and the 5 dead ones had stutter dial tones because of waiting voice mail.

So I changed the PBX programming on these OPX's to disable the stuttering dial tone and now all 8 are working fine.

Is this just a nature of the beast sort of thing with these T1/channel bank systems?

Thanks.

PERSONALLY I NEVER HEARD OF MW STUTTER DIALTONE KEEPING A T1 CHANNEL FROM WORKING

Did you try putting the stuttered dial tone option back on one of the lines to confirm that was indeed causing the issue? As long as the format is correct for the channel, it "should" not cause this issue, but I have never worked with that type of Channel bank before, so I am not sure of the specs.

I'll be at the remote site sometime later this week or early next week - will dial into the PBX, play around with it and see what happens.

I'm not familiar with the channel bank hardware either - and it's a pain in the rear to deal with a vendor who points the finger at everyone else.

It will be interesting to see what your findings are. I have worked on Premisys CBs in the past, and never had an issue like that. Understanding how channel units operate, it seems odd that stutter dialtone could or would affect using a line. What happens when the lines are called?
