I would think it's kind of obvious, but since it isn't.... :) Don't put a dchan in spans 2, 3, and 4, and don't block out those channels as available cics. Also, aren't there 32 channels in an E1, not 31? -------------- span=1,1,0,ccs,hdb3,crc4 bchan=1-15,17-32 dchan=16 span=2,2,0,ccs,hdb3,crc4 bchan=33-64 span=3,3,0,ccs,hdb3,crc4 bchan=65-96 span=4,4,0,ccs,hdb3,crc4 bchan=97-128 -------------- cicbeginswith=1 channel=1-15 sigchan=16 cicbeginswith=17 channel=17-32 cicbeginswith=33 channel=33-64 cicbeginswith=65 channel=65-96 cicbeginswith=97 channel=97-128 -------------- You might even get away with cicbeginswith=17 channel=17-128 But that's not something I've tried.
