Function
Low-power Standby Status.
Writing to this bit causes temporary manual control of this bit until a subsequent on-hook
or off-hook transition.
0 = low-power mode off (i.e. Active off-hook).
1 = low-power mode on (i.e. Active on-hook).
Audio Squelch Control.
Indicates squelch of audio during the setting time set by the SPEEDUP RAM coefficient.
Writing to this bit causes temporary manual override until a speedup event occurs.
0 = Squelch off.
1 = Squelch on.
Audio Filter Capacitor Bypass.
Indicates filter capacitor pass during the setting time set by the SPEEDUP RAM coeffi-
cient. Writing to this bit causes temporary manual override until a speedup event occurs.
0 = Capacitors not bypassed.
1 = Capacitors bypassed.
SLIC Bias Enable.
Writing to this bit causes temporary manual control of SLIC bias until a subsequent on-
hook or off-hook state.
0 = SLIC bias off (i.e. Active on-hook).
1 = = SLIC bias on (i.e. Active off-hook).
SLIC Bias Level, On-Hook Transmission State.
DC bias current flowing in the SLIC circuit during on-hook transmission state. Increasing
this value increases the ability of the SLIC to withstand longitudinal current artifacts.
00 = 4 mA per lead.
01 = 8 mA per lead.
10 = 12 mA per lead.
11 = 16 mA per lead.
SLIC Bias Level, Active State.
DC bias current flowing in the SLIC circuit during the active off-hook state. Increasing this
value increases the ability of the SLIC to withstand longitudinal current artifacts.
00 = 4 mA per lead.
01 = 8 mA per lead.
10 = 12 mA per lead.
11 = 16 mA per lead.
