sundance-communications.com/forum Forums Other TDM Phone Systems Executone-Isoetec Telephones & Systems 228 T-1 problems

Update: Well the channel bank worked for awhile. Now both local and LD drop calls. Replaced everything! Still same problem, local and LD are seperate companys, both say what they always do "no trouble found" I also have Toll options set to no, still dropping. I work with many Executone systems and have never seen something like this.

Have you checked the clocking cable on the t-1? What is the configuration of the circuits. Line type 84 doesn't seem right? E-mail me with some information of the situation. I beleive it is mci. If the circuit is a t-1, set up a phone with direct appearance of the t-1 channels and try making some calls in or out and see if the calls go through or if you can answer them right away.

I was going to stay out of this since I don't know the switch. Still would like to know if the T1's ESF or D4 and who's the supplier. Most the suppliers have 24/7 monitoring on T1's.

AMI/D4, I am dealing with Verizon, MCI, XO Comm, and Matrix. So any time I have to do anything I have four companies to deal with. The equipment onsite is Verizon and thier c/o. When I get the drop the display shows
"Line Release".

If I were you, I would try posting this problem in the "T-1" forum, below. I seriously doubt that this is the switch. I would hope that someone there has some more insight into this.

Then I'm back to my original statement. Other than slips you can't monitor for errors on D4, it has to be taken oos and tested ESF. I do realize the problems with all the different suppliers, but you report it too whoever you ordered it from and they deal with all the others. Unless of course you ordered base line to save money. Believe me most new techs don't know you can't reliably monitor errors on D4, I dealt with it for years.

Update: Well after all these HUGE stroms here in Florida, Verizon has had alot of trouble from the storm dropping calls, etc.
well after they fixed all the problems in ther c/o I have had no dropped calls on this 228 since! What a kick in the pants! All along I was telling everyone that the c/o had some issues and no one would listen should I tell them all "I told you so"...maybe not.

Thanks for all the help!
