Using TCCS - E1 to T1 not working above channel 16

Using T-CCCS there is an E1 on on side and a T1 on the other, the timeslots are mapped 1-2,2-2,3-3,4-4...16-24,17-17,18-18...23-23. The D-channel is on the E1 TS16 and the T1 TS24. This works fine for TS1-15, starting a TS17 there is no voice path or ring back, yet both sides show trunked. Any suggestions?

Since there has been no response to your post, it appears to be either too complex or too rare an issue for other forum members to assist you. If you don't get a suitable response to your post, you may wish to review our resources at the online Technical Assistance Center (http://www.cisco.com/tac) or speak with a TAC engineer. You can open a TAC case online at http://www.cisco.com/tac/caseopen

If anyone else in the forum has some advice, please reply to this thread.

Thank you for posting.
