Dial Tone Delay

[suitz]

We have A G3R which occasionally is providing phones with a delay in dial-tone. There are plenty of TONE boards, and only one call classifier.

All occupancy and TONE measurements always show 0 blockage/ queued or denials.

Is there anything else that could cause the delays? It only happens occasionally and is not a constant.

Do you have any ring-gen or power errors?

 

[suitz]

Yes - I do see some POWER errors. These are Tyoe 3840 AUX 1005 and on serveral cabinets...

and are there any TN748 boards still in the system? common issue on an R.

-CL

 

[suitz]

No - I checked and I do not have any TN748 Tone Detectors.

I ran into power issues on old G3s, but not 100% sure if it affected ring-gen or not?

You may try attempting the test environment xx long clear tests, that the Avaya G3 maintenance manual suggests. There are various power tests that you can do.

I found something interseting this morning.

When running the measurements against the TONE I found that 2 PNs are getting all of their TONE from other PNs instead of getting it from itself. These 2 cabinets are using TN768 TONEs while all others PNs are using TN2182C.
Nowhere in the documentation have I read where using two different types of TONE board will cause an issue, but it definetly is here.

We are changing the TN768 out with TN2182C to see if this resolves the issue...
