Has anyone heard of this problem: On 5 of our 3com TC Chassis's which are all on Erickson switches and using D4-AMI, we cannot get connected via a long distance call. The local dial-up customers are connecting just fine. Using hyperterminal, we get repeating "U"'s on the screen for about 50 seconds, then the connection drops. If we dial in using a 1010321 (MCI I believe), we get a clean connection for about 110 seconds, then that connection drops. We had a similar problem occur in a different town, but that was on a DMS-10 switch and a telco translator fixed the problem with a switch setting. On the call I make, the disconnect reason is "remote hungup during training (80)". I have talked to our telco (Qwest) and they have checked with translations and everything is set up correctly (or so they say). We had a similar problem with a 3com on a DMS-10 switch and the local telco (Citizens) was able to fix the problem that time. It had to do with a "answer supervision" setting on the switch.
