Receive Gain Selection
The <gain> parameter has a range of 112-134 with 128 marking the nominal value.
The default is 128, which represents 0 dB. Step size is 3 dB. This represents a
range of -48 dB to 18 dB. This command is used to control the receive gain at the DTE
from either the Si3000 Codec or the DAA. The purpose is to adjust the DTE receive
gain for the TAM voice stream during idle state. See the <DLE><d> and <DLE><u>
commands discussed in Table 111 on page 178 for information on how to control the
receive gain during active voice stream processing.
Transmit Gain Selection
The <gain> parameter has a range of 112-134 with 128 marking the nominal value.
The default is 128, which represents 0 dB. Step size is 3 dB. This represents a
range of -48 dB to 18 dB. This command is used to control the transmit gain at the
DTE to either the Si3000 Codec or the DAA. The purpose is to adjust the DTE transmit
gain for the TAM voice stream during idle state. See the <DLE><d> and <DLE><u>
commands discussed in Table 111 on page 178 for information on how to control the
transmit gain during active voice stream processing.
