10. DS0 MONITORING FUNCTION
Each framer in the DS21Q50 has the ability to monitor one DS0 (64kbps) 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 CCR3 register. In the receive
direction, the RCM0 to RCM4 bits in the CCR4 register 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 E1 channel. 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 CCR4 and CCR5:
TCM4 = 0
RCM4 = 0
TCM3 = 0
RCM3 = 1
TCM2 = 1
RCM2 = 1
TCM1 = 0
RCM1 = 1
TCM0 = 1
RCM0 = 0
