There may be a problem in how the telco is handling channels that don't respond to the wink to initiate the call. In our case we occasionally have a quad modem port that stops answering calls. The telco would initiate multiple wink attempts then fail the call. The customer got rings during the attempts, then the line was dropped. The telco fixed this by immediately moving to a new channel when the wink fails. All the customer experiences is a few more seconds of ringing until the new modem responds. I review our chassis's daily for failing modems, and occasionally the telco will call me to warn me about a particular channel that is cluttering their error log. It doesn't have anything to do with the quality of the lines.

Ok, I am coming here to get some solid advice on an outstanding issue with our CT1s. I am looking at my TC boxes ( quads and HiperDSP). Off and on we get customer calls that say it just keeps ringing. I try it and sure enough, the TCs are not answering. But i look at teh boxes via TCM and I have loads of capacity on all circuits. 2 minutes later or 20 minutes later, or even 2 hours later it is fine. GTE (Great Terrible Epidemic) says my lines are ok. Passing all tests.
I am running the following code verisons
Hiper DSP 2.0.51
Hiper ARC 4.1.22
Quads 5.9.9
Any advice or help is greatly appreciated.
