6.0 DS0 MONITORING FUNCTION
The DS2154 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 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 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 (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 (timeslot 5) in the transmit direction and DS0
Channel 15 (timeslot 14) 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
