9.9.10 DS0 Monitoring Function
The DS26514 can monitor one DS0 (64kbps) channel in the transmit direction and one DS0 channel in the receive
direction at the same time.

Note: The addresses shown above are for Framer 1. Addresses for Framers 2 to 4 can be calculated using the following: Framer n = (Framer 1
address + (n - 1) x 200hex), where n = 2 to 4 for Framers 2 to 4.
In the transmit direction the user will determine which channel is to be monitored by properly setting the TCM[4:0]
bits in the
properly set. The DS0 channel pointed to by the TCM[4:0] bits will appear in the Transmit DS0 Monitor Register
(TDS0M) and the DS0 channel pointed to by the RCM[4:0] bits will appear in the Receive DS0 Monitor Register
(RDS0M). The TCM[4:0] and RCM[4:0] bits should be programmed with the decimal decode of the appropriate
T1or E1 channel. T1 channels 1 to 24 map to register values 0 to 23. E1 channels 1 to 32 map to register values 0
to 31. 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 TDS0SEL and RDS0SEL:
