no Dial Tone on Analog Cards

no Dial Tone on Analog Cards


Have an issue with no Dial Tone on eight Analog cards on a shelf - the cards are sitting in slots 0 - 7 on a Dual Core Option 81. The ports ring when called but they keep ringing when you go off-hook (in other words you can't answer or make calls). There is another Analog card in the same shelf on slot 8 that is working fine.

Can someone please provide intput?

Thank you!

RE: no Dial Tone on Analog Cards

Did these work before? What do you see when you TRAC in LD 80?
If they did not work before then I would guess that the amphenol connectors could be mixed up or disconnected at the back of the shelf. Can you IDU the cards in LD 32?
If they were working and suddenly stopped then maybe the controller card has failed.
Try a LOOP test on that loop in LD 30 for a clue.

RE: no Dial Tone on Analog Cards

sounds like an issue with the controller card

RE: no Dial Tone on Analog Cards

Yes, they worked fine.

As a reference, how do you perform the LOOP test in LD 30?

And thank you for your input! A power cycle of the IPE shelf cleared the issue.

LD 30
.loop lll
.loop all

or also
.shlf lll s
would work.

controller card and or ring generator

RE: no Dial Tone on Analog Cards

Thank you for the feedback! It was the Controller Card and a power cycle of the shelf corrected the problem.
