Default
Bits 1 and 0: Receiver Sensitivity/Monitor Gain Select (RSMS[1:0]). These bits are used to select the receiver
sensitivity level and additional gain in monitoring applications. The monitor mode (RMONEN) adds resistive gain to
compensate for the signal loss caused by the isolation resistors. See
Table 10-23. Receiver Sensitivity Selection with Monitor Mode Disabled
Table 10-24. Receiver Sensitivity Selection with Monitor Mode Enabled
Rev: 101608
Bit 7: Receive G.703 Clock (RG703). If this bit is set, the receiver expects a 2.048MHz or 1.544MHz clock from
the RTIPn/RRINGn, based on the selection of T1 (1.544) or E1 (2.048) mode in the
Bit 3: Receiver Turns Ratio (RTR)
Bit 2: Receiver Monitor Mode Enable (RMONEN)

0 = Receive transformer turns ratio is 1:1.
1 = Receive transformer turns ratio is 2:1. This option should only be used in short-haul applications.
Note: Internal impedance match is not available for this mode.
0 = Disable receive monitor mode.
1 = Enable receive monitor mode. Resistive gain is added with the maximum sensitivity. The receiver
sensitivity is determined by RSMS1 and RSMS0.
