You only need to use the Booster that will help your problem, either trouble ringing,low talk battery loop current or low volume on an OPX. Its unlikely youll need. The combination of both the Loop Current Booster. PLUS and Ring Voltage Booster II is functionally equivalent to the old Proctor Long Loop Adapter 4. While the Proctor Long Loop Adapter didnt pass Caller ID, CPC, or FSK, Neon or LED Message Waiting signals, all of our Boosters will pass those signals without a problem. These Boosters wont interfere with Distinctive Ringing, Call Waiting, Call Transfer or 3 Way Calling features. The Ring Voltage Booster II increases the ring voltage to 9. VAC RMS at 2. 0 cycles, with a 7. REN output, and a true SINE WAVE output which should be recognized by even the most finicky telephone equipment. The Loop Current Booster PLUS will. VDC to whatever the on hook talk. The Long Line Volume Booster increases. Phone Companies who can put one at the CO, as. OPXs on PBXs. It works like Load Coils, but load coils have to be.

AC voltage on a phone line, which always has DC talk battery on it too. You can see information. AC ring voltage in our in our Ring Voltage Tech Bulletin. LOOP CURRENT BOOSTER PLUSLoop Current Booster PLUSIncreases the Loop Current to a Regulated 2. Increases the On Hook Talk Battery by 2. VDCThe Loop Current Booster PLUS simply adds 2. VDC to the on hook talk battery. If the on hook hung up talk battery on a line is 2. V, the Loop Current Booster PLUS will raise the on hook voltage to 4. VDC. The off hook DC voltage would be the same as any phone line with 2. The Loop Current Booster PLUS will boost loop current from a CO line or station port providing as low as 1. VDC.

Some phone companies no longer offer any conditioning for an OPX. They wont install repeaters or condition the line for you. The Loop Current Booster PLUS boosts the talk battery and loop current, so you can get many non conditioned or improperly conditioned OPXs to work.

Modern phone system station ports typically have less than 4. VDC talk battery, so placing the Loop Current Booster in series between the station port and the telco OPX demarc will make the loop current and talk battery look more like a standard phone line to the phone company.
