I had a T3 card get randomly confused a few months ago and wouldn't responding to commands properly. Ended up doing an OIR on it to reset it and called the whole thing "weirdness happens". Mine was off a Verizon OC-12 to Adtran OPTI-6100 mux (with OC-3, DS3, and DS1 cards). ~Seth _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
