Operational Description
IOM-2 data access
0:

Coding
000:
no PCM coding (16-bit linear data)
001:
A-law coding (8-bit data)
010:
µ-law coding (8-bit data)
all other codes reserved
For the pump modes V.110 and bypass “no PCM coding” must be
selected.
A-law and µ-law coding is selected for all modulation related pump
modes (fax, datamodem and halfduplex modulation, DTMF and DTMF
transmission). If "no PCM coding" is selected in these modes, 16-bit
linear values are output on the IOM-2 interface.
Rate Conversion
RCV refers to internal operation of the device and must be set depending
on the pump mode.
