10. DS0 MONITORING FUNCTION
Each framer in the DS2196 has the ability to monitor one DS0 64 kbps channel in the transmit direction
and one DS0 channel in the receive direction at the same time. In the transmit direction the user will
determine which channel is to be monitored by properly setting the TCM0 to TCM4 bits in the CCR5A &
CCR5B registers. In the receive direction, the RCM0 to RCM4 bits in the CCR6A & CCR6B registers
need to be properly set. The DS0 channel pointed to by the TCM0 to TCM4 bits will appear in the
Transmit DS0 Monitor (TDS0M) register and the DS0 channel pointed to by the RCM0 to RCM4 bits
will appear in the Receive DS0 (RDS0M) register. 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 in the transmit direction and DS0 channel 15
in the receive direction needed to be monitored, then the following values would be programmed into
CCR5 and CCR6:
TCM4 = 0
TCM3 = 0
TCM2 = 1
TCM1 = 0
TCM0 = 1
RCM4 = 0
RCM3 = 1
RCM2 = 1
RCM1 = 1
RCM0 = 0
