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.
