9. DS0 MONITORING FUNCTION
The device 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 CCR5 register. In the
receive direction, the RCM0 to RCM4 bits in the CCR6 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 T1 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
CCR5 and CCR6:
TCM4 = 0
TCM3 = 0
TCM2 = 1
TCM1 = 0
TCM0 = 1
RCM4 = 0
RCM3 = 1
RCM2 = 1
RCM1 = 1
RCM0 = 0
