The TCM4 to TCM0 and RCM4 to RCM0 bits should be programmed with the decimal decode of the
appropriate T1 channel. Channels 1 through 24 map to register values 0 through 23. For example, if
DS0 channel 6 (timeslot 5) in the transmit direction and DS0 channel 15 (timeslot 14) in the receive
direction needed to be monitored, then the following values would be programmed into CCR5 and
CCR6:
TCM4 = 0
RCM4 = 0
TCM3 = 0
RCM3 = 1
TCM2 = 1
RCM2 = 1
TCM1 = 0
RCM1 = 1
TCM0 = 1
RCM0 = 0
