Re: E1 Controller problem

Hi Arjun ,

Check the encapsulation configured for serial interfaces on both the routers..it must be either hdlc or ppp on both the routers.

Please send us " show controller " and show interface output of both the routers.

Did you check the framing, line code and clock source with your provider what type of parameters they configured on their end.

Cheers

MSK :)

Re: E1 Controller problem

Hello Arjiun,

I think it should be:

controller E1 1/1

framing NO-CRC4

channel-group 1 timeslots 1-31 speed 64

or you want to use only timeslot 31 ?

Hope to help

Re: E1 Controller problem

Please check with Service provider if the provisioned link or Circuit is Framed or unframed.

so you have to co-ordinate with the Service provider,

as the VWIC-1MFT-T1/E1 Cards supports

controller E1 0/0/0

framing NO-CRC4

channel-group 0 timeslots 1-31

or you if you have G703 controller card

" VWIC2-MFT-G703" or VWIC2-2MFT-G703

controller E1 0/0/0

channel-group 0 unframed
