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 ?

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.

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
