Answered Question
Jan 29th, 2009

I have read that chanelized E1 cards like NM-1CE1T1-PRI have no built in D channels.Signaling is done inband

Can this card be used for ISDN PRI connection in a central site where the company has several branch offices having WIC-1B-U-V2 card ?

I have this problem too.

Hi, you can have 15 remotes office with two calls each. If you never configured ISDN I suggest you hire a reputable professional to help, however it is explained in the documentation.

Do not configure channel-groups as incorrectly suggested by a poster above.

Thanks for the nice rating and good luck.

That is incorrect, all channelized cisco cards have full support for D-channel in all Q.931 and QSIG variants (voice).

So yes the card is indicated and will work.

In that case what is the maximum number of remote routers that i can add?

I am having one one central office and several remote offices and the 2 Mgbs isdn link is in central office while 128KPBS isdn link is in remote office.

Can you provide sample configurations ?

see the only thing you have to do is create time slots like below.(this example gives 64kb in each time slot if you need more please add time slots 5-7 like this for more bandwidth)

channel-group 1 timeslots 1

channel-group 2 timeslots 2

channel-group 3 timeslots 3

channel-group 4 timeslots 4

then automatically serial interfaces will be created.assign ip addresses to each of these logical interfaces.

hope you have LL at remote branches.

pls rate if it helps
