Jay-- I have had similar experience with some T3s from Vz. I like to unplug and replug as you and Gert noted. Plus I like to keep some spare coax and adapters hanging around my routers. When I invariably receive the "it's the CPE" I loop the cables and ask them if they see a loop. That shuts them up fast. ;-)

PE router showed interface up, line protocol down. CE router showed down/down. Provider side goes to an Adtran Opti-mux out OC-12 to Verizon, customer end is a Verizon mux on premise. Called Vz and they claimed it was CPE, they saw "idle loop" towards our 7206 CE router. We shut/no-shut the interface and rebooted the 7206, no joy. I'm not familiar with the term "idle loop", we were showing receive LOS and sending RAI. Customer IT guy came on site and saw CLOS on Verizon mux, alarm light on 7206. He disconnected the cable and put a coax loop towards the 7206. Interface came up-looped right away. Reconnected to Verizon mux and everything came back up nice and happy. That's what is bugging me. Circuit has been running fine for months. -- -- Jay Hennigan - CCIE #7880 - Network Engineering - [email protected] Impulse Internet Service - http://www.impulse.net/ Your local telephone and internet company - 805 884-6323 - WB6RDV cjw _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
