Spark Quenching.
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.
OHS
Spark Quenching.
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.
OHS
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.
Guarded Clear Enable (Line-side Revision E or later).
This bit (in conjunction with the R2 bit set to 1), enables the Si3056 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.
