Re: E1 line with packet drops

Hi

(1)You have not given model no of the E1 card and the router in which they are used?

(2)Are the E1 cards working back-to-back?

Typically they should.

(3)Also check the jumper settings for the balanced and unbalanced PRI?

Pls revert back if any probs.

Regards

JD

Re: E1 line with packet drops

hi jd,

E1 is 1U-MFT, it supports only max of 2 channels.

modem used is atrie wirespan 5000.

E1 card and modem both are working fine.so where could i check this jumper settings.

its working setup, but crc should be cleared frequently, even then link goes down.

Hello,

in addition to the other posts, you might want to check the clock settings on your E1, make sure it is set to ´clock source line´...

Re: E1 line with packet drops
