Description
Transmitter analog output
The TXAO can supply a maximum of 3.03 V
PK
into a load
resistance of 10K
( minimum ).
An external analog smoothing filter with transfer function 28735.63 /
( S + 11547.34 ) is required.
Receiver analog input
The input impedance of RXAI is greater them 1M
.
An external analog anti - aliasing filter with transfer function
21551.72 / ( S + 11547.43 ) is required between the line interface
and the modem RXAI input.
The maximum input signal level into the anti-aliasing filter should
not exceed 0 dBm.

Auxiliary analog input
The transmitter output ( TXAO ) can be accessed by user equipment
through AUXAI.
Since this is a sampled input any signals with frequency components
higher than 4800Hz ( half of the sampling rate ) will cause aliasing
errors.
The input impedance of AUXAI is 1M
and the gain to TXAO is
0 dB
±
1dB.
