ROUTER E1 OR PABX E1 PROBLEM

[cfajardo1_2]

my router is coonected to the pabx thru e1. Iam suddenly getting the below output of my sh controller e1 0/0/0

sh controllers e1 0/0/0

E1 0/0/0 is down.

Applique type is Channelized E1 - balanced

Far End Block Errors Detected

Transmitter is sending remote alarm.

Receiver has loss of frame.

alarm-trigger is not set

Version info Firmware: 20090113, FPGA: 20, spm_count = 0

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

Data in current interval (218 seconds elapsed):

3769310 Line Code Violations, 30126 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, 218 Unavail Secs

HOW WILL I KNOW WHICH ONE IS FAULTY? MY E1 OR THE PABX E1?

THANKS

Likely cabling problem. However, you should use clock source internal when connecting PBX.

hi,

This was working for 2 months now.

Hi Paolo,

Can we say here that the e1 card is okay?

thanks

Router rarely fails.

Check cabling and configure internal clock.

[cfajardo1_2]

one thing, the e1 configs are still intact on the configuration. doesnt this dictate that the hardware is okay?

controller E1 0/0/0

pri-group timeslots 1-31

interface Serial0/0/0:15

no ip address

encapsulation hdlc

isdn switch-type primary-net5

isdn incoming-voice voice

no cdp enable

No.

You can do loopback tests, but in most cases it's just wasting time, because the problem is something else.
