  Network Clock Configuration

  ---------------------------

  Priority      Clock Source    Clock State     Clock Type

     1          E1 0/0/0        GOOD            E1

    10          Backplane       GOOD            PLL

  Current Primary Clock Source

  ---------------------------

  Priority      Clock Source    Clock State     Clock Type

     1          E1 0/0/0        GOOD            E1

Sh controller e1

E1 0/0/0 is up.

  Applique type is Channelized E1 - balanced

  No alarms detected.

  alarm-trigger is not set

  Version info FPGA Rev: 08121917, FPGA Type: PRK4

  Framing is CRC4, Line Code is HDB3, Clock Source is Line.

  International Bit: 1, National Bits: 11111

  Data in current interval (353 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

  Total Data (last 24 hours)

     1 Line Code Violations, 1790 Path Code Violations,

     1 Slip Secs, 90 Fr Loss Secs, 1 Line Err Secs, 0 Degraded Mins,

     44 Errored Secs, 4 Bursty Err Secs, 34 Severely Err Secs, 95 Unavail Secs

Even I got so many Input and CRC errors in Sh Inter se 0/0/0:15....

So please tell me excat solution....to resolve this issue

You can use commands "network-clock-participate" and "network-clock-select" to set synchronization parameters.

If the problem remains you can check the circuit with your telco.
