I am having a problem on three incoming CT1's that are terminated by the T1 card to quad modems. We are seeing "bipolar violations", "code violation errors", and "bursty errored seconds". The telco has looked into the hdsl carrier and it shows no errors. Neither does the central switch. They put a tcomm tester on the T1 to watch the data and it reported "secondary channel loss", but they are unable to determine what that means in the context of a T1. I began looking for problems when the number of people complaining about not being able to stay online jumped significantly today. They report the problem has been going on for the past two days. Does anyone have any thoughts on what these errors point to? The telco is going to replace cards in the central switch this weekend, and I'm considering resetting the T1 cards to see of that is it. I appreciate any help you can give.

We have seen problems from bad CO line cards in the past so its definitely a possibility. -Dan - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

We have had the problem with a Dual PRI card and it turned out to be bad and not the telco's fault. If you have a spare handy it sure wouldn't hurt to try that. Marshall Morgan Internet Doorway, Inc. (aka NETDOOR)

Twice in the last week, our netserver has gone south. After much trial & error, I found I could revive it by: 1. Power cycling the router 2. Entering following commands: disable ip network ip163a delete ip network ip163a add ip network ip163a address 209.74.163.2/25 interface eth:1 enabled yes I have to enter these commands via seral port since for all intents & purposes, the ethernet port is dead. Any ideas? Only change we made in last couple of weeks was to give one of our clients 2 blocks of IP addresses as follows: set network user HBC1 ADDRESS_SELECTION specified remote_IP_address 209.74.163.209/29 ADD FRAMED_ROUTE USER HBC1 GATEWAY 209.74.163.209 IP_ROUTE 209.74.163.208/29 METRIC 2 add ip route 209.74.163.216/29 METRIC 5 GATEWAY 209.74.163.209 Should I handle this differently?

Line coding errors - an AMI - B8ZS mismatch somewhere - anywhere - in the call path? See http://808hi.com/56k/coding.htm Line coding errors may be much bigger issue than some think - can also occur in telco/clec facilities between subscriber and your switch - something you have little control over! CT1 = beginning of recipe for 56k trouble get PRI if at all possible.
