A while back, the phone company moved the old copper T1 circuits at one of our POPs onto fiber. From that day forward, *Many* users have experienced connection problems: can't connect, frequent disconnects. These users can dial other POPs and connect fine. Multiple trouble tickets with the phone company have resulted in multiple switch technicians going through the phone company's switch configuration, but none have found anything wrong. Some customers seem to connect fine, others can't connect at all. The over-all utilization of this POP has dropped 40% - 50% since the switch to fiber. Users began calling out other POPs. The problem "seems" to be related to where a customer calls from. We have provided phone numbers of example customers who are experiencing the problem to the phone company, but they haven't been able to find anything. Has anyone ever experienced anything like this? We are running multiple chassis all running Hiper DSPs at this POP. Thanks, Kevin. ------------------------------------------------------ Kevin Hemsley Systems Engineer kev@ida.net NF7J
