Last month when configuring a PRI Assuming that its a MFT-T1/E1 card, i used “pri-group timeslots 1-31” . After a while i noticed there is no serial interface created.
Later verifying the inventory i noticed that NIM card inserted was Voice/Channelized Data T1/E1 Module and not Voice/Clear-channel Data card.
If you are using line cards NIM-XCE1T1-PRI for your PRI , use below command to configure the PRI .
controller e1 0/1/0
pri-group timeslots 1-X voice-dsp
You need to add voice-dsp along with the Pri time slot command.
To configure the PRI if you have already used “pri-group timeslots 1-X” command , entering the above command you will received below warning.
Cannot change voice-dsp configuration. Unconfigure existing pri-group and reconf igure.
So to reconfigure the controller, Remove the pri-group timeslot command and use pri-group timeslots 1-X voice-dsp
