Each DS21Q58 framer 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 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 appear in the
transmit DS0 monitor (TDS0M) register and the DS0 channel pointed to by the RCM0 to RCM4 bits 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
