Router Cisco 1921 (VWIC3-2MFT-T1/E1)  ===> SDH Hauwei <===========> SDH Hauwei =====> Modem Datacom ==> Cisco 2911 (HWIC-2T)

Router Cisco 1921

This type of topology works ? 

I tryed to configuring unframe E1 but it does not accepted the commands.

ex: 

Router(config-controller)#channel-group 0 unframed
^
% Invalid input detected at '^' marker.

Marce1000,

In my case i have two type of interface (VWIC3-2MFT-T1/E1 and HWIC-2T) in each site and i would like establish communication beetwen them with HDLC protocol.

I think that i need do a unchannalized configuration on module VWIC3-2MFT-T1/E1 with command:  "channel-group 0 unframed" , but it is not working.

Does anyone have any ideia how it works ?

How can i do this kind of the configuration ?

Hello @santos_ligeiro ,

if you have SDH ADM in the middle you can use a framed E1

controller e1 0/0

channel-group 1 1-15,17-31

timeslot 16 is the control channel D  and timeslot 32 is used for framing.

Hope to help

Giuseppe

Hello Giuseppe Larosa

In my case I do not have access to SDH , however i will speak to responsible person about this kind of configuration on SDH.

BUT Is there another way to solve this problem just by configuring the Cisco Rotuers?
