You can make your ss7.conf look like this: ; First E1 with signalling on timeslot 16 [link-l1] channels => 1-15,17-31 schannel => 16 firstcic => 1 ; Second E1 with no signalling and audio on 31 timeslots.

It would be a shame to have unused timeslots on an E1. fortunately you can avoid this :) Mvh. Jacob -- Jacob Tinning System Developer SIFIRA A/S
