Spark Quenching. Si3018 and Si3019 line-side only.
This bit, in combination with the OHS bit (Register 16), and the OHS2 bit (Register 31), sets
the amount of time for the line-side device to go on-hook. The on-hook speeds specified are
measured from the time the OH bit is cleared until loop current equals zero.

2RG1
Receive Gain 1 (Line-side Revision E or later).
This bit enables receive path gain adjustment.
0 = No gain applied to hybrid, full scale RX on line = 0 dBm.
1 = 1 dB of gain applied to hybrid, full scale RX on line = –1 dBm.
1GCE
Guarded Clear Enable (Line-side Revision E or later).
This bit (in conjunction with the R2 bit set to 1) enables the Si3050 to meet BT’s Guarded
Clear Spec (B5 6450, Part 1: 1993, Section 15.4.3.3). With these bits set, the DAA will draw
approximately 2.5 mA of current from the line while on-hook.
0 = Default, DAA does not draw loop current.
1 = Guarded Clear enabled, DAA draws 2.5 mA while on-hook to meet Guarded Clear
requirement.
0
Reserved Always write this bit to zero.
