D-Channel
The Japanese 2Mbit trunk circuit pack, when administered to support ISDN-PRI signaling,
allows you to assign the D-channel to any channel from 1 to 31 in an E-1 facility. You cannot
submit the screen if this field is blank. Using the change ds1 command, you can change this
field if the D-channel is not used in a signaling group. This field appears only when the Location
field indicates the circuit pack is a Japanese 2Mbit trunk circuit pack and the Signaling Mode
field is isdn-pri.
Valid entries
1 to 31
