CM Trunk Group question - 255 member limit but need to add more circuits/lines

[cleveland]

Have isdn trk grp toll free inbd, NFAS signaling with 10 PRIs, 238 members. Trk Grp member size in CM is limited to 255. But I need to add 2 more PRIs, all B channels, to give more lines. I know I can add my 2 new circuits ds1 boards to existing signal grp but with the Trk Grp member size limit, not enough room to add 48 more B channels into existing Trk Grp. Could I add the 2 new circuits (ds1s) to the existing Signaling grp, then build a 2nd, new isdn Trk Grp, and add the 48 new B channels there and assign them to the existing Signaling grp? Thanks for any info.

Yes it can be done but you may face issue that 2nd trunk is not coming up.
I have experienced similar situation and had to add separate D channel and trunk.

Just add trunks with same signalling group to second trunk group - what do you get?
