D channel on E1 ISDN link

[kuldeep.kaur]

Hi there,

I would like to know if I implement a 10 channel using a E1 ISDN service, what will be the interface number for the D channel. For example if I implement a full E1 ISDN, the D channel is normally on Serial0:0:15

Thanks Guys

D-channel will remain the same even for partial PRI.

"The B channel numbers range from 1 to 31; channel 16 is the D channel for E1. Corresponding serial interfaces numbers range from 0 to 30. In commands, the D channel is interface serial controller-number:15. For example, interface serial 0:15"
