Phone line power booster
increases number of phones and boosts volume.



[tr][td]

Under Federal law, your local phone company is only required to provide enough power to ring the bells in four standard phones. Some phones vary in their power requirement, and you may be able to get away with six phones, but probably not more.

Here's a handy device that is capable of ringing twelve standard ("1 REN") telephones or phone-like devices and does not affect the normal operation of the telephone line or features provided by the phone company, such as Caller ID and Call Waiting.

Our booster is designed to increase ringing power of an analog telephone line, VoIP line, Cable TV phone line, analog PABX extension, analog ISDN Terminal Adapter port, or any other telecom device which provides ringing.

It duplicates the incoming ring frequency and cadence so it is compatible with distinctive ringing services.

Applications

• Boost ring power from ISDN Terminal Adapter analog ports.
• Use with Viking Doorboxes to increase the number of phones to ring.
• Boost ring power on telephone lines or analog PABX stations that are weak or failing.
• Correct ring waves from equipment such as automatic fax switches.
• Increase power to flash lights on phones such as BatPhone.

LOOP CURRENT BOOSTER™

Loop Current Booster™

Increases the Loop Current to a Regulated 27ma
Increases the On-Hook Talk Battery by 24VDC
The Loop Current Booster™ simply adds 24VDC to the on-hook talk battery. If the on-hook (hung-up) talk battery on a line is 24V, the Loop Current Booster™ will raise the on-hook voltage to 48VDC.
The off-hook DC voltage would be the same as any phone line with 27ma of loop current.
The Loop Current Booster™ will boost loop current from a CO line or station port providing as low as 15ma of loop current, at 20 to 48VDC.
The Loop Current Booster™ does not change the ringing voltage or current, and does not provide any audio gain. One Loop Current Booster™ is required per line.
Some phone companies no longer offer any conditioning for an OPX. They won抰 install repeaters or condition the line for you. The Loop Current Booster™ boosts the talk battery and loop current, so you can get many non-conditioned (or improperly conditioned) OPXs to work.
When used on an OPX (Off-Premise Extension), the Loop Current Booster™ is normally placed at the near-end of the circuit (where the dial tone originates). Modern phone system station ports typically have less than 48VDC 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.
If there抯 not enough loop current on a phone line or at the far-end of an OPX (below 23ma), phones will sometimes not work properly (they might have dialing and/or talking problems). When the Loop Current Booster™ is used in-series with the pair entering a premise, it increases the loop current and talk battery voltage. You may need a Loop Current Booster™ on each end of an OPX.
A Line In-Use LED indicator is located on the face of the Booster.
The CPE equipment (telephones) connected in-series with the Loop Current Booster™ will work without 110VAC power, but you will have no boost of the talk battery or loop current. It will simply pass the line through.
The Loop Current Booster™ has modular connections for both the telephone line or station port, and the telephone equipment.
Includes 110VAC to 24VDC 100ma unregulated power cube. Do not substitute a different power transformer!
220VAC International Power Cube is available.
