Hi

i feel these pin details would help u out..

Pin 1 to 4

Pin 2 to 5

Basically the mentioned pairs are correlated to TX , RX..

If it doesnt work u mite need to try

1 ----- 4

2 ----- 5

4 ----- 1

5 ----- 2

the above pin details includes RX/TX ring pair points too in addition with RX/TX pair..

Hi

How far have you got so far?

You'll need to enter

clock source internal

Under the E1 controller on one router... then configure your signalling types/etc - what type of setup are you trying to create?

Re: E1 Back to Back

Are you trying to configure this as a E1 PRI for transporting voice calls ?

set both sides with linecode, framing and a pri-group command specifiying number of channels. Under the D channel, set one end as network side and other end as user side (defaults). (isdn protocol-emulate network | user)
