8.8.1.3 Maximum Levels
The 73M1x66B is capable of providing gain attenuation in both the digital and analog domain. It is important
to note that for optimum performance the transmitter output and receiver input should not exceed more than
+7.25 dBm. Signal levels that are greater than this will cause distortion and reduced performance.
This implies that the maximum input signal capable by the transmitter, if adjusted for unity gain, is the
+7.25 dBm, e.g. digital gain of -6.0 dB (ensures analog input is less than +1.25 dBm) and analog gain of
+6 dB gives +7.25 dBm.

Time Slot Assignment Example
Figure 31 shows an example of the timing of transmit and receive time slots with changes in the time slot,
clock slot and edge controls. Refer to Section 8.8, PCM Control Functions.
To program the first transmit time slot after
FS, TTC=31, TCS=7 and TPOL=1:
The first receive time slot after
FS would be RTS=31, RCS=7 and RPOL=0.
Adjustments of clock period can be made using these registers.
