(usr-tc) erickson switch - long distance calls
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.

Ok.. Ive been reading with interest the on-going v.92 discussions over the last couple of weeks.. One question thats bugging me is.. Everyone is talking about the support for 24port and 96 port DSP.... However what about us non-US people with DSP30port E1's ???? I assume its an oversight that it hasnt been mentioned at all.... ??

The 30 port E1 cards are, for all intents and purposes, the same beast as the 24 port T1 cards. I understand that they run different software releases, but they're largely the same. I would assume that if support for v.92 is in the 24 ports DSPs, it'll be in the 30 port versions as well. -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

Pretty much same card... You can usually assume that anything for the 24-port card is the same for the 30-port one. I don't ever think I've seen a code relase for 24-port cards, and not for the 30-port ones. ------------------------------------------------------------------------- | Curtis V.

I really don't know anything about Erickson switches, and I don't think this would even be possible on a nortel or lucent w/o building a separate trunk group. But you might check to see what they are sending you for digits on long distance calls with a T1 test set. It's possible they are sending you two strings instead of one, the first (for example) containing the II and ANI digits, the second containing the DNIS. If your chassis is only expecting one string, it's going to cut thru the call while the switch is waiting for the chassis to wink back the second string. Eventually the swicth times out waiting for the second wink back. -a On Wed, 21 Mar 2001, Michael Fingerson wrote:
