[USR-TC] Channel T1 to PRI

Hey guys, anyone have a minute to help a guy into the 20th century? We are converting our service form Channelized T1 to PRI. I know on the T1 setting on the DSP we need to: Set the type from robbed bit to message oriented. Check the difference in dtmf or mf the number of digits My question is on the dsp and the chassis. I have the cards set statically and I have set the type as HDM_24 and the port density set to 24, should I change this to 23? Terry Kennedy OlyPen, Inc.
