On-Hook Line Voltage.
The value written to this bit sets the on-hook line voltage polarity (VTIP–VRING).
0=VTIP–VRINGis positive
1=VTIP–VRING is negative
5:0
VOC[5:0]
On-Hook Line Voltage.
The value written to this register sets the on-hook line voltage (VTIP–VRING). Value may
be set between 0 V (0x00) and 94.5 V (0x3F) in 1.5 V steps. Default value = 48 V.

VCM[5:0]
Common Mode Voltage.
The value written to this register sets VTIP for forward active and forward on-hook trans-
mission states and VRING for reverse active and reverse on-hook transmission states.
The value may be set between 0 V (0x00) and –94.5 V (0x3F) in 1.5 V steps. Default
value = –3 V.
