no PCM coding
A-law coding
μ
-law coding
A-law and
μ
-law coding is selected for all modulation related pump modes (fax, datamodem
and halfduplex modulation, DTMF and DTMF transmission). For all other modes (V.110 and
bypass mode) "no PCM coding" must be selected.
RCV ... Rate Conversion
RCV refers to internal operation of the device and must be set depending on the pump mode.
