i mean here to use other router not customer router & apply a loop at last point on telco line before connected to the frame switch

telco fiber mux--cisco balun---rj45---customer router E1 interface. No coxial cable customer internal wiring

What router / interface is this with the problem? E1 ? Can you send show controllers e1 ?

Which pinout/paring for the rj45 cable between router and balun ?

Thanks for your feedback.., really appreciated,

here is show controller E1. Latest sh controller E1 show almost 40000 path code violation which all error triggered

E1 0/0/0 is up.

Applique type is Channelized E1 - balanced

No alarms detected.

alarm-trigger is not set

Version info Firmware: 20050620, FPGA: 16, spm_count = 0

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

CRC Threshold is 320. Reported from firmware is 320.

Data in current interval (74 seconds elapsed):

0 Line Code Violations, 33 Path Code Violations

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

0 Errored Secs, 0 Bursty Err Secs, 3 Severely Err Secs, 0 Unavail Secs

Please send "show network-clock" and related config commands for network-clock-participate ans network-clock-select.

Wich IOS are you running? Is this a VWIC or VWIC2? There is newer firmware in latest IOS I believe.

Also important, please verify the rj45 cable to balun is NOT a standard ethernet cable. At very minimum, it must be crimped per t1/E1 cabling that is different than ethernet.

I cannot login on frame relay switch or customer router.I just received the sh int,sh controller by email from my oversea ally, I m telco engineer , all the router manage remotely by my company oversea ally.

Thats why i m asking to do extended ping test using different router to prove no problem on the line even though its proven using telco BERT tester.

Thanks for the feedback

Hi,

the thing is that is the above commands are required in the router to make the circuit work clean of errors, and also the cable used is important as incorrect cabling can cause errors.

Once you have these two facts verified, you may think what would be the next troubleshooting step.

Thanks for your info. It's quite difficult/impossible for me to get the command as all the configuration is a secret by the ally(giant company in the world).

What i can do now to follow your advised is to re-check the cable pinout.

else to argue with them there is really no problem on the line

Here we are not talking about the complete configuration, but just two commands needed to make layer 1 work well. And the "show" command to verify that.

The cable as I said is very important as TE/E! must use ping 1-2 and 4-5 with twisted pairs, that is different from ethernet, unfortunately many installer don;t care and use any sapre ethernet patch and tis is wrong.

Good luck.
