 mode atm
 line-term cpe
 line-mode 4-wire standard
 dsl-mode shdsl symmetric annex B
 line-rate 4608

interface ATM0

IP route 0.0.0.0 0.0.0.0 10.10.10.2

what is the cable type you used, and what is the type of router?

i try to connect cisco router 1921 to cisco router 888 using SHDSL

in 1921 ----- RJ-45

in 888 ----- Rj-11

do you have any idea to how to connect this

[Masoud Pourshabanian]

Cisco 888 has embedded SHDSL , but for 1921 you need to get a module.

1921 supports  HWIC-2SHDSL and  HWIC-4SHDSL  Do you have one of those module?

[fouad-zeyad1]

yes my bro

i have HWIC-4SHDSL in 1921

[Masoud Pourshabanian]

If you are using two lines, connect middle pins of 1921 (pins 4 and 5) to middle pins of 888 (pins 2 and 3). Middle pins are for line 0 for both router.

if you are using four lines, connect

(pins 4 to 2)

(pins 5 to 3)

(pins 1 to 1)

(pins 2 to 4)

Two assign 4 lines to a dsl group use this command

dsl-group 0 pairs  0-1

Please see the diagram attached.

Hope it helps

[fouad-zeyad1]

OK , thanks my brother

i want to try and reply 

[Masoud Pourshabanian]

 HWIC-2SHDSL has RJ11 connector  and HWIC-4SHDSL has RJ45 connector.

Please look at picture attached to see pins arrangement If you have HWIC-4SHDSL.

Hope it helps,
