TLV320AIC1110: Signals input from PCMIN are output again to PCMOUT with -4 dB gain adjustment.

Hi, 

<Question 1>
I want to output the received signal as analogue signal 1 and input analogue signal 1 again externally to the same PCM codec in order to transmit it to the next terminal as well. Would the signal not be recognised as the same level and input as described in the following data sheet?
------
Overload-signal level (3 dBm0) in the 'transmit...' table:
124 mVpp (normal mode)
Overload-signal level (3 dB) in the 'receive...' table: 1.925 Vpp
------

<Question 2>
In the block diagram on p. 5, an arrow runs from 'Digital Modulator and Filter' to the front of 'Analog Modulator'. Even without external circuitry as in question 1, would the incoming signal from PCMIN be output again to PCMOUT with a -4 dB gain adjustment in default mode?


Thanks,

Conor
