Channelized T1 Port Adapter Installation and Configuration  49

Configuring 2CT1 Interfaces

The following example of the show interfaces serial port adapter slot number/interface port
number:pri-group
 command shows all of the information specific to the same interface (interface
port 1 in port adapter slot 1) when the interface is configured for ISDN PRI:

Router# show interface serial 1/1:23

Serial1/1:23 is up, line protocol is up (spoofing)

  Hardware is MPA-T1

  Internet address is 10.1.15.1

  MTU 1500 bytes, BW 1984 Kbit, DLY 20000 usec, rely 255/255, load 1/255

  Encapsulation HDLC, loopback not set

  Last input 00:00:42, output 00:00:56, output hang never

  Last clearing of “show interface” counters never

  Input queue: 0/75/0 (size/max/drops); Total output drops: 0

  Queueing strategy: weighted fair

  Output queue: 0/64/0 (size/threshold/drops)

     Conversations  0/1 (active/max active)

     Reserved Conversations 0/0 (allocated/max allocated)

  5 minute input rate 0 bits/sec, 0 packets/sec

  5 minute output rate 0 bits/sec, 0 packets/sec

     149 packets input, 40207 bytes, 0 no buffer

     Received 298 broadcasts, 0 runts, 0 giants

     0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

     128 packets output, 44416 bytes, 0 underruns

     0 output errors, 0 collisions, 0 interface resets

     0 output buffer failures, 0 output buffers swapped out

     20 carrier transitions no alarm present

  Timeslot(s) Used:1-24, subrate: 64Kb/s, transmit delay is 0 flags

Note

In the above example, the term “spoofing” indicates that the interface is configured for ISDN

PRI. The term ”spoofing” is indicated only on timeslot 24 (the D channel), which is recognized by
the system as timeslot 23.

Use the show controllers t1 [port adapter slot number/interface port number] command to display
the status of each installed T1 interface. The following example of the show controllers t1
command shows the status of a 2CT1 port adapter installed in port adapter slot 1, interface port 0:

Router# show controllers t1 1/0

T1 1/0 is up.

  No alarms detected.

  Framing is ESF, Line Code is B8ZS, Clock Source is Line.

  Data in current interval (710 seconds elapsed):

     0 Line Code Violations, 0 Path Code Violations

     0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

     0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs

  Data in Interval 1:

     0 Line Code Violations, 0 Path Code Violations

     0 Slip Secs, 0 Fr Loss Secs, 0 Line Err Secs, 0 Degraded Mins

     0 Errored Secs, 0 Bursty Err Secs, 0 Severely Err Secs, 0 Unavail Secs
