One of my USR-TC chassis appears to be dying or it's dead already. It's the old 2059 bundle with Quad modems and a Netserver card. I first noticed a problem Sunday morning when I came in to do a system upgrade. It seemed strange that TC rack had zero calls and the other TCs had about 10 calls each. One of the modem cards on the rack was in alarm, so I powercycled the rack. The modem card just flashed red after, so I reflashed the card and all was well. Now, tonight I got a call saying callers were getting dead air. There were callers up on the rack, but far fewer than the other racks. I called in, and sure enough most calls to that rack got dead air, with the modem led going red instead of orange. I soft busied that rack, but every single caller on the rack eventually got dropped with a lost carrier. 5 of the callers got a lost carrier within 2 seconds. I pulled the dead modem card from the rack and power cycled it. After that, every single caller gets dead air, but the modem lights now go orange instead of red. I took the modem rack out of service until tomorrow. Where do I start on fixing this? Do I just declare it a total loss and buy a new one? I do have spares for every part except the modem cards. (The T1s are good, as they work on some extra modem ports I have.) Brian - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
