8. DS0 MONITORING FUNCTION
Each framer in the DS21354/DS21554 can 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
determines which channel is to be monitored by properly setting the TCM0 to TCM4 bits in the CCR4
register. In the receive direction, the RCM0 to RCM4 bits in the CCR5 register need to be properly set.
The DS0 channel pointed to by the TCM0 to TCM4 bits appears in the transmit DS0 monitor (TDS0M)
register, and the DS0 channel pointed to by the RCM0 to RCM4 bits appears 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 need
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
