[cisco-voip] Anyone ever see a T1 with CD, No alarms and be down...?

[Jonathan Charles]

Serial0/0/0:23 is down, line protocol is down
  Hardware is DSX1
  MTU 1500 bytes, BW 64 Kbit/sec, DLY 20000 usec,
     reliability 252/255, txload 1/255, rxload 1/255
  Encapsulation HDLC, loopback not set
  Last input never, output never, output hang never
  Last clearing of "show interface" counters never
  Input queue: 0/75/0/0 (size/max/drops/flushes); Total output drops: 0
  Queueing strategy: weighted fair
  Output queue: 0/1000/64/0 (size/max total/threshold/drops)
     Conversations  0/1/256 (active/max active/max total)
     Reserved Conversations 0/0 (allocated/max allocated)
     Available Bandwidth 48 kilobits/sec
  5 minute input rate 0 bits/sec, 0 packets/sec
  5 minute output rate 0 bits/sec, 0 packets/sec
     0 packets input, 0 bytes, 0 no buffer
     Received 0 broadcasts, 5 runts, 0 giants, 0 throttles
     20 input errors, 20 CRC, 0 frame, 0 overrun, 0 ignored, 14 abort
     5 packets output, 15 bytes, 0 underruns
     0 output errors, 0 collisions, 0 interface resets
     0 unknown protocol drops
     0 output buffer failures, 0 output buffers swapped out
     2 carrier transitions
  Timeslot(s) Used:24, SCC: 0, Transmitter delay is 0 flags

Down down as expected when the controller is down...
