Product Details

• Increases Ring Voltage to 90VAC RMS at 20 Cycles.

• Increases Ringing Current to 7.5 REN.

• True SINE WAVE output, should make anything ring!

• Ground wire for systems requiring grounded ringing

NOTE: This version of our Ring Voltage Booster II is for Grounded Ringing which references the tip side of the line to Ground using a ground wire. The standard version (#KIT8R) supports Bridged Ringing (voltage is sent between the tip and ring) and works with most modern telephone equipment. If the ground wire isn't attached to ground, the Ring Voltage Booster II with Grounded Ringing is exactly the same as our standard Ring Voltage Booster II.

If you aren't sure whether you need Grounded Ringing, buy the Ring Voltage Booster II with Grounded Ringing, since it will work in either scenario.

The Ring Voltage Booster II provides 7.5 REN of 90VAC RMS Ringing to any telephone equipment wired in-series with the Booster. That's enough for more than 7 of the old style 2500 sets with bell ringers. Each of those phones uses about 1 REN.

The Ring Voltage Booster II will boost ringing from as low as 30VAC RMS. It regenerates the ringing of the telephone line or station port, matching the ring pattern very closely. It does not change the talk battery voltage or loop current, and does not provide any audio gain. One Ring Voltage Booster II is required per line.

Boosts Ringing On:
• Telephone Lines
• Analog Station Ports
• Analog ISDN Ports
• T1 Channel Bank Ports
• VoIP Adapter Analog Ports
• Any Device that provides a Port for an Analog Telephone

A lot of modern telecom devices do a poor job of emulating a real phone line, and have pretty bad ringing!

A "Real" analog phone line from a phone company usually provides around 5 REN of ringing on a telephone line. Adding a Ring Voltage Booster will allow you to put over 11 REN worth of phones on a line. Plug around 4 REN directly into the line from the phone company, and plug 7 REN into the Ring Voltage Booster II (which would be bridged directly to the phone line).

Cable provider phone boxes, Analog Telephone Adapters (ATAs) and devices like the MagicJack or Ooma typically provide 1.5 to 2.5 REN. Adding a Ring Voltage Booster is the only way to get more than a couple phones ringing properly on these devices.

You need to know how many REN you're putting on a phone line or adapter. The REN value is marked on the bottom of each modern phone. Most are now well under 1 REN, although some are more than 1 REN.

The Ring Voltage Booster II will boost the ringing from phone system analog station ports, which often have low ring voltage, less than 1 REN of ringing current, and a Square Wave for ringing (instead of a true SINE wave as provided by the real phone company).

The ring voltage standard is lower in Europe (around 60VAC RMS), so if the phone system or device providing dial tone and ring voltage was designed in Europe, the Ring Voltage Booster II could be the only way to get your CPE equipment to ring!

When used on an OPX (Off-Premise Extension), the Ring Voltage Booster II is normally placed at the far-end of the circuit (where the CPE equipment is), to regenerate the ring. You may need a Ring Voltage Booster II on each end of an OPX, particularly if the ringing is weak coming out of the phone system's station port and the OPX runs a long ways. You may need the Ring Voltage Booster II on the near end (at the PBX) if it's an OPX, and the phone company's equipment (like a repeater) doesn't recognize the ringing from the phone system's analog station port.

Modular RJ-11 Jacks for easy connection to the telephone line or station port, and the telephones.

This version has a ground wire to support Grounded Ringing. If the ground wire isn't attached to ground, the Ring Voltage Booster II with Grounded Ringing functions exactly the same as our standard Ring Voltage Booster II.

There are no switches on the Ring Voltage Booster II, but there is an LED will that will indicate when the ring voltage is being boosted.

The CPE equipment (telephones) on LINE-OUT will still work without 110VAC power applied to the Ring Voltage Booster II, but you will have no boost of the ring voltage or current. It will simply pass the line through.

Includes a 110VAC to 12V Regulated Power Cube and Line Cord.

A 220VAC International Power Cube is available.

If you need to put in a lot of Ring Voltage Boosters at once location, our 25-Line Chassis version offers a clean rack-mount installation for up to 25 lines.
