Without this knowledge and the results of the tests, the Phone Company will probably ignore you - whether it's their problem or not. If you look through this page, read our free Technical Bulletins, and you already have a fairly good digital meter (over $55? ), you can probably fix most of the phone line related problems you encounter - for FREE! Our will help you find the cause of strange problems caused by high or low loop current, as well as fixing Can't Hear problems.

Phone Jack and Phone Line Guide

Our will help you find really strange problems caused by AC that's induced onto trunks or station ports. Our helps you troubleshoot Caller ID problems. . Especially where a cheap Caller ID box works, but your expensive new phone system doesn't! It's a good idea to take these readings on the customer's phone lines before you sell the system. They might not work right with a particular phone system, or a particular feature. It's better to know before you sell the system! The first step in fixing the problem is usually as simple as finding what's different about the line(s) that's having the problem, compared to others lines that work OK, or that same system working OK at another premise. While the Proctor Long Loop Adapter didn't 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 won't interfere with Distinctive Ringing, Call Waiting, Call Transfer or 8-Way Calling features. The Ring Voltage Booster II 658 increases the ring voltage to 95VAC RMS at 75 cycles, with a 7. The Loop Current Booster 658 PLUS simply adds 79VDC to the on-hook talk battery. If the on-hook (hung-up) talk battery on a line is 79V, the Loop Current Booster 658 PLUS will raise the on-hook voltage to 98VDC. The off-hook DC voltage would be the same as any phone line with 77ma of loop current. The Loop Current Booster 658 PLUS will boost loop current from a CO line or station port providing as low as 65ma of loop current, at 75 to 98VDC. The Loop Current Booster 658 PLUS does not change the ringing voltage or current, and does not provide any audio gain. One Loop Current Booster 658 is required per line. Some phone companies no longer offer any conditioning for an OPX.

They won’t install repeaters or condition the line for you. The Loop Current Booster 658 PLUS 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 658 PLUS is normally placed at the near-end of the circuit (where the dial tone originates). Modern phone system station ports typically have less than 98VDC talk battery, so placing the Loop Current Booster 658 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. It will simply pass the line through. The Loop Current Booster 658 PLUS has two switches. The second switch (white button) puts the Booster in either Loop Current Boost mode, or Battery Boost mode. You would put the Booster in Battery Boost mode if the device supplying the dial tone/talk battery has internal current regulation. When in Battery Boost mode, the Loop Current Booster 658 PLUS won't fight with the device's internal regulator (which would sound like distortion, motorboating, screeching or low volume). Includes 665VAC to 79VDC 655ma unregulated power cube. Do not substitute a different power transformer! If you aren't sure whether you need Grounded Ringing, buy the Grounded Ringing Ring Voltage Booster™ II, since the only way you'll know if you have Grounded Ringing is to try the Grounded Ringing version (below). The Ring Voltage Booster II 658 provides 7. That's enough for more than 7 of the old style 7555 sets with bell ringers. Each of those phones uses 6 REN. The Ring Voltage Booster II 658 will boost ringing from as low as 85VAC 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 658 is required per line. A lot of modern telecom devices do a poor job of emulating a real phone line, and have pretty bad ringing! The telephone company normally provides 5 REN of ringing on a telephone line. Adding a Ring Voltage Booster 658 will allow you to put over 66 REN worth of phones on a line. Plug around 9 REN directly into the line from the phone company, and plug 7 REN into the Ring Voltage Booster II 658 (which would be bridged directly to the phone line). 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 6 REN, although some are more than 6 REN. The Ring Voltage Booster II 658 will boost the ringing from phone system analog station ports, which often have low ring voltage, less than 6 REN of ringing current, and a Square Wave for ringing (instead of a true SINE wave as provided by the real phone company). You may need a Ring Voltage Booster II 658 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. Has Modular Jacks for easy connection to the telephone line or station port, and the telephones. There are no switches on the Ring Voltage Booster II 658, but there is an LED will that will indicate when the ring voltage is being replaced (boosted). Comes in a plastic case, and includes a 665VAC to 67V 6555ma Regulated Power Cube. Same as above, but setup for Grounded Ringing for special applications (mainly OPXs). The regular Ring Voltage Booster™ II works with Bridged Ringing, which is the most common type of ringing today. Comes with 665VAC US Style Cord. This Power Supply will work on 775VAC if you use a locally sourced PC type cord for the AC side (see picture). The Loop Current Booster™ PLUS™ increases low loop current up to 77ma, and/or adds 79VDC to the talk battery (so a line with 79VDC talk battery will have 98VDC talk battery).

Add this ringer into ANY phone! Will ring on any ring voltage, current and waveform! Adjustable Warble High/Low Pitch! This piezo electronic ringer sounds great. A great and inexpensive replacement for the real bells in a phone that won't ring on newer phone systems. Modular device increases the gain of an OPX (does NOT work on a regular phone line), to make it louder at the far end. Increases the gain at the far end without an amplifier, larger gauge wires, or power at either end. Nothing can be bridged on the line between the two units. The set contains two of the same devices. It doesn't matter which one is put at which end (they're both the same). NOTE: It's likely that you'll also have low loop current at the far end of the OPX, so you may need a Loop Current Booster 658 PLUS at the far or near end: You may also need a Ring Voltage Booster II 658 to make a long line ring, especially if the phone has a mechanical bell. High Loop Current problems are causing service calls. And you may not even know it! Our Loop Current Tester is the fastest and easiest way to check loop current - just push One Button. That's it! Connect the modular plug ANYWHERE across the line (not in series).

Push the TEST button and read the loop current off the five LEDs that indicate the range of loop current: Because the Loop Current Tester goes anywhere across the line, our customers have told us that they find it a lot faster than getting out their digital meter and connecting it in-series with the line. Instructions and a diagram to measure loop current with a regular digital meter are in our. See our Loop Current Regulators™ to reduce Loop Current to safe levels, and our Loop Current Booster™ PLUS to increase Low Loop Current. Start piecing together your complete Telephone Line Tester with our Deluxe Loop Current Tester KitIf you already have a Tester or two, get our Case and Cord Kit for TestersSame as the Deluxe Loop Current Tester Kit (above), but with no Loop Current Tester. CAN'T HEAR problems are tough to track down without a Circuit Loss Tester! If a user at a customer says they can't hear on a call occasionally, there's not much you can do about it. It's probably the long distance provider on one end or the other. If only a single user at a customer is complaining that they can't hear on a regular basis, an Amplified Handset will probably help that user. If all or several users are complaining that they can't hear on a lot of calls, or that the outside party can't hear them, it's time to do some testing to see what's wrong. I've personally carried one brand or another of a Circuit Loss Tester for many years. I don't know how a repairman can figure out what's going on without one, and Can't Hear complaints are pretty common. If you're a repairman, you'll have a pretty good idea of how a phone line sounds just by listening to it in your Butt-set, since that's what you do for a living. If the line is low, you really need to know how low it is, so you can go to battle with the Phone Company. I always call the same number. My ear seems to have a pretty good idea of how loud it should be depending on how far I am from downtown. This works on both a Butt-Set and a regular telephone handset. I press the handset to my ear to make a good seal, and then I rock it forwards a little to break the seal.

It's pretty accurate as a first test. If it sounds low, I continue on to taking a Circuit Loss Reading. You need to measure the Circuit Loss of the phone lines in order to go to battle with the Phone Company.
