LONG LOOP ADAPTERS


25 Line Ring Voltage Booster      Ring Voltage Booster II      Loop Current Booster

BOOST Loop Current, Ring Voltage & Increase the Volume of a Long Line

Our Loop Current Booster™ PLUS / 25 Line Loop Current Booster™, Ring Voltage Booster II™ / 25 Line Ring Voltage Booster™ and Long Line Volume Booster™ / 25 Line Long Line Volume Booster™ will let you extend the distance that an analog station port (OPX) or telephone line will work.

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.  It's unlikely you'll need all of the boosters unless the pair is very long, or the analog station port is particularly weak.

The combination of both the Loop Current Booster™ PLUS and Ring Voltage Booster™ II is functionally equivalent to the old Proctor Long Loop Adapter (46222, or 46224).

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 3-Way Calling features.

The Ring Voltage Booster II™ increases the ring voltage to 90VAC RMS at 20 cycles, with a 7.5 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 increase loop current to 27ma, and/or add 24VDC to whatever the on-hook talk battery is.

The Long Line Volume Booster™ increases the gain of a phone line or station port if you can put one at each end of the line (works well for Phone Companies who can put one at the CO, as well as for OPXs on PBXs). It works like Load Coils, but load coils have to be placed at specific locations along the pair in the field. That's both difficult and expensive The Long Line Volume Booster™ does the same thing by just placing one at each end of the pair. And it doesn't need power on either end.

More details on Circuit Loss are in our Loop Current and Circuit Loss Tech Bulletin.

Please note that measuring ring voltage isn't easy! No two makes and models of meters will read the same on the same line (they could be as much as 10 volts off), and some modern digital meters just won't read AC voltage on a phone line, which always has DC talk battery on it too. You can see information about measuring AC ring voltage in our in our Ring Voltage Tech Bulletin.

RING VOLTAGE BOOSTER II™

Ring Voltage Booster II



Ring Voltage Booster II™

Increases the Ring Voltage to
90VAC RMS at 20 cycles

Increases Ringing Current to 7.5 REN

True SINE WAVE should make
anything Ring!

NOTE: This version of our Ring Voltage Booster II™ is for Bridged Ringing (voltage is sent between the tip and ring) and works with most modern telephone equipment. We have another version (farther down the page) that provides Grounded Ringing which references the tip side of the line to Ground using a ground wire. If the ground wire isn't attached to ground, the Ring Voltage Booster II™ with Grounded Ringing is exactly the same as our Regular Ring Voltage Booster II™.

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).

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 1 REN.

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 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!

The telephone company normally provides 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).

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.

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™, but there is an LED will that will indicate when the ring voltage is being replaced (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.

Comes in a plastic case, and includes a 110VAC to 12V 1000ma Regulated Power Cube.

220VAC International Power Cube is available.

25 LINE RING VOLTAGE BOOSTER

25 Line Ring Voltage Booster










 

 

 



 

 

              25 Line Ring Voltage Booster™

                                         Populate in 5 Line Increments!

            Increases Ring Voltage to 90VAC RMS at 20 cycles

                       Increases Ringing Current to 7.5 REN

                True SINE WAVE should make anything Ring!


The 25 Line Ring Voltage Booster™ is a 19” rack mount chassis with 25 pair AMP connectors for input and output. The electronics are exactly the same as our Ring Voltage Booster II™ (above).  If you want to make sure this will solve your problem, buy a single line Ring Voltage Booster II™ to see if it will help, before ordering a 25 Line unit.

It’s placed in-series with up to 25 analog station ports or phone lines and the phone equipment that needs the increased ring voltage or current. It regenerates the ringing of the telephone line or station port, matching the ring pattern very closely.

The 25 Line Ring Voltage Booster™ will boost the ringing on a phone line or station port that’s 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 DC loop current, and does not provide any audio gain. It just boosts the Ring Voltage and Current. Nothing else.

One Ring Voltage Booster™ Module is required per line, and one Ring Generator Module is required for every five lines (it’s not necessary to populate all 25 lines if they’re not needed). It's populated in 5 line increments.

Ring Voltage Booster™ Module

Ring Generator Module

5 Lines Populated

One plug-in Ring Generator Module serves each five plug-in Ring Voltage Booster™ Modules (one Booster Module is needed per line).


The chassis can be populated with up to 5 Ring Generator Modules (RG1 through 5), and 25 Ring Voltage Booster™ Modules. One 4A 12VDC Regulated Power Supply plugs into a jack on the rear panel.

Each Ring Generator Module puts out 7.5 REN of 90V Sine Wave ringing current, which is used by the five associated  Ring Voltage Booster™ Module ports.

Traffic Considerations:

If only one of the five ports associated with a Ring Generator Module is ringing, it will get the full 7.5 REN output of that Ring Generator. If two ports are ringing at the same time, each port will split the 7.5 available REN. Likewise, if three, four or all five ports are ringing simultaneously, they will all split the available 7.5 REN.

Normally you’ll only have one 1 REN or less attached to each port in a PBX environment. If all five ports ring at the same time, there will be plenty of current to ring all five.

If you have 5 REN worth of phones/ringers on each port, it will take 25 REN to ring them all simultaneously, and none will ring because that’s more current than the Ring Generator Module can provide.

The chances of all five ports ringing at the same time are slight, but it’s possible. Most phone systems stagger the ringing on analog ports so they don’t need a huge ring generator (which is fairly annoying in an office environment where several phones are programmed to ring on an incoming call).

If you have a lot of REN on each port, and you can assign stations that ring at different times to the ports associated with a single Ring Generator Module, you’ll have 7.5 REN available to each port. If you only have a few ports with a lot of phones/ringers, split them up between the five Ring Generator Modules in the 25 Line Ring Voltage Booster™

Feature Compatiblity:

The 25 Line Ring Voltage Booster™ works with CPC (Calling Party Control, or Open Loop Disconnect), Caller ID, Message Waiting (may have a problem with some Neon and LED type message waiting), Distinctive Ringing, Call Waiting, Call Transfer and 3-Way Calling. It regenerates the ringing of the telephone line or station port, matching the ring pattern very closely.

The 25 Line Ring Voltage Booster™ Boosts Ringing On:

• Telephone Lines     • Analog Station Ports     • Analog ISDN Ports     • T1 Channel Bank Ports

• VoIP Adapter Analog and Gateway Ports     • Any Device  that provides a Port for an Analog Telephone
 

Note that 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™ could be the only way to get your CPE equipment to ring!

There are no switches on the 25 Line Ring Voltage Booster™.  There are LEDs to indicate power to the 25 Line Ring Voltage Booster™, when a Ring Generator Module is supplying power, when a Ring Voltage Booster™ Module is providing power (replacing the ringing for that portion), and when there is an overload on a Ring Generator Module.

The CPE equipment (telephones) on the output will still work without power applied to the 25 Line Ring Voltage Booster™, but you will have no boost of the ring voltage or current. It will simply pass the line through.

INTERNAL 90V ELECTRONIC RINGER

Piezo Electronic Interneal Ringer




Add this ringer into ANY phone!

Will ring on any ring voltage,
current and waveform!

Adjustable Warble High/Low Pitch!






  • 1 REN
  • Somewhat louder than a standard bell in a 2500 or 2554 phone, depending on where the warble is adjusted.
  • Since it's electronic (not a mechanical ringer - there's no clapper being activated by electro-magnets like in a real bell), it's likely to ring on even the crummiest ring voltage of modern phone systems and devices (disconnect the old bell!).
  • The sound is adjustable from a slow low pitch warble to a fast high pitch warble with a small pot on the board (not adjustable from outside the phone).
  • Variable pitch makes it easy to identify different phones that are near each other (as does our Large LED Ringing Indicator).
  • Tiny Ringer is 1.5" by 1.5", by .75" tall.
  • Comes with double stick tape to mount it inside the phone.
  • No volume control.

  • 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.

    LOOP CURRENT BOOSTER™ PLUS

    Click to see a bigger picture of the Loop Current Booster

    Loop Current Booster™ PLUS

    Increases the Loop Current to a Regulated 27ma

    Increases the On-Hook Talk Battery by 24VDC

    The Loop Current Booster™ PLUS 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™ PLUS 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™ PLUS 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™ PLUS 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’t 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.

    When used on an OPX (Off-Premise Extension), the Loop Current Booster™ 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 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’s 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™ PLUS 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™ PLUS 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™ PLUS 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™ PLUS has two switches. One switch (red button) is flipped on initial installation to match the polarity of the line. 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™ PLUS won't fight with the device's internal regulator (which would sound like distortion, motorboating, screeching or low volume).

    The Loop Current Booster™ PLUS 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.

    LONG LINE VOLUME BOOSTER™ - SET OF TWO!

    Long Line Volume Booster™

    Modular device increases the gain of an OPX (does NOT work on a regular phone line),
    to make it louder at the far end.

    Works the same way as load coils do to increase the gain on a line, but you don't need to place them in the outside plant.
    One at the near end, one at the far end, and that's it!

    No power required at either end!

    Increases the gain at the far end without an amplifier, larger gauge wires, or power at either end.

    You MUST use two, one at each end!

    Most phone companies no longer offer any conditioning for an OPX. They won't install repeaters or condition the line for you.
    The Long Line Volume Booster™ boosts the volume at the far end of the OPX so the user can hear OK.

    All CPE equipment (telephones) must be connected in-series with the Long Loop Volume Booster™ at the FAR 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).

    Modular IN and OUT. Connect one at each end, and that's it!

    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™ PLUS at the far or near end:

                An Unbelievably Good Meter for a Phone Man, at a Very Reasonable Price!


    NOTE: The Meter color is now Red instead of Yellow due to a Copyright dispute on the color Yellow used on a Meter. Other than the color, it's the exact same meter.


    We bought and tested lots of meters to find one that was accurate for the phone man who has to measure:

    • On and Off Hook DC Voltage
    • DC Loop Current
    • Induced AC Voltage on a Phone Line
    • AC Ring Voltage

    It's amazing how many meters, even expensive ones, won't measure AC on a phone line. You know you can't use a meter for telephone work if the display just hunts from 50 to 100 to 10 to 200 to 30, etc., constantly. Most Flukes work OK.

    Network Meter™ DVOM Features:

    • AC and DC Volts
    • AC and DC Current (DC mA for Loop Current)
    • Ohms
    • Continuity with Beeper
    • Hold Button to Freeze the Display
    • Large Numbers on the LCD Display
    • Bright White Backlight for the Display (Switchable On/Off)
    • CAT5 4 Pair Cable Tester with Remote (Shows Continuity and Split Pairs)
    • Flip Out Desk Stand, with Helpful Connection Tips under the Stand
    • Overvoltage Protection prevents Meter Damage
    • Comes with Regular 9V Heavy Duty Battery - Lasts an Incredibly long time!
    • NOTE: There is an RJ-11 Test on the Selector Switch that's not Implemented

    The Network Meter™ is really easy to use!

    Phone line and phone system problems are getting harder, and a meter is as important as ever for a phone man who needs to get problems fixed as quickly and efficiently as possible... before you replace the KSU!

    The Network Meter™ is at least as good at reading AC ring voltage as the $800 to $1,000 Triplett Model 5 or Sidekick T&N Meters, and it's accurate on all of the other ranges too - including DC ma (for loop current).

    I put 50VDC from a phone line into the Cable Tester and Remote RJ-45 jacks, as well as the meter's ohms range, and the meter still worked (no smoke!). Not all meters or cable testers can survive an accidental connection to a phone line - which is a real possibility when we're out in the field. With PoE (Power over Ethernet), a lot of CAT5 jacks in offices are going to have 48VDC on one of the pairs that can instantly destroy a cable tester without overvoltage protection.

    See the Ring Voltage Tech Bulletin for more information on ringing problems, and reading AC voltages on phone lines.

    • Remote for the Cable Tester

                An Unbelievably Good Meter for a Phone Man, at a Very Reasonable Price!


    NOTE: The Meter color is now Red instead of Yellow due to a Copyright dispute on the color Yellow used on a Meter. Other than the color, it's the exact same meter.


    We bought and tested lots of meters to find one that was accurate for the phone man who has to measure:

    • On and Off Hook DC Voltage
    • DC Loop Current
    • Induced AC Voltage on a Phone Line
    • AC Ring Voltage

    It's amazing how many meters, even expensive ones, won't measure AC on a phone line. You know you can't use a meter for telephone work if the display just hunts from 50 to 100 to 10 to 200 to 30, etc., constantly. Most Flukes work OK.

    ECONOMY Network Meter™ DVOM Features:

    • AC and DC Volts
    • AC and DC Current (DC mA for Loop Current)
    • Ohms
    • Continuity with Beeper
    • Hold Button to Freeze the Display
    • Large Numbers on the LCD Display
    • Bright White Backlight for the Display (Switchable On/Off)
    • CAT5 4 Pair Cable Tester with Remote (Shows Continuity and Split Pairs)
    • Flip Out Desk Stand, with Helpful Connection Tips under the Stand
    • Overvoltage Protection prevents Meter Damage
    • Comes with Regular 9V Heavy Duty Battery - Lasts an Incredibly long time!
    • NOTE: There is an RJ-11 Test on the Selector Switch that's not Implemented

    The ECONOMY Network Meter™ is really easy to use!

    Phone line and phone system problems are getting harder, and a meter is as important as ever for a phone man who needs to get problems fixed as quickly and efficiently as possible... before you replace the KSU!

    The ECONOMY Network Meter™ is at least as good at reading AC ring voltage as the $800 to $1,000 Triplett Model 5 or Sidekick T&N Meters, and it's accurate on all of the other ranges too - including DC ma (for loop current).

    I put 50VDC from a phone line into the Cable Tester and Remote RJ-45 jacks, as well as the meter's ohms range, and the meter still worked (no smoke!). Not all meters or cable testers can survive an accidental connection to a phone line - which is a real possibility when we're out in the field. With PoE (Power over Ethernet), a lot of CAT5 jacks in offices are going to have 48VDC on one of the pairs that can instantly destroy a cable tester without overvoltage protection.

    See the Ring Voltage Tech Bulletin for more information on ringing problems, and reading AC voltages on phone lines.

    NOTE: There has been a bug in all Fluke TS52PRO Butt-sets made since around the 20th week of 2011. The date code in the white area above the MUTE button would say 2011 through 0114.

    The bug only occurs if you have high loop current on the line. Maybe over 45 to 50ma, which you can see on the built-in display.

    If you turn on the speakerphone and go off-hook to dial a call, when the call is answered the call is immediately cut-off and the microprocessor in the butt-set reboots (the back-light comes on and all the characters are shown on the display). If you turn the speakerphone on after the other party answers the butt-set works fine.

    This bug doesn't make the butt-set unusable, but why buy an expensive speakerphone butt-set if you can't use the speaker when dialing out, if there is high loop current on the line?

    If you already have one of the defective butt-sets you can get one of our Loop Current Regulators and put it in-series with the line with high loop current, but that's not exactly convenient!

    Until recently Fluke refused to acknowledge the bug. They now refuse to fix it. If you send it to an authorized Fluke repair facility that can fix stuff under warrantly, they won't be able to fix it because Fluke won't give them the parts to fix it.

    We do have TS52PROs in-stock at this great price if you don't mind that one bug.

    Need to know what kind of Central Office the Phone Company is using?

    How about the address of the Central Office?

    Click Here to do a CO Lookup!  
    Click Here
    to do a CO Lookup!

    Use our CO Lookup to find out which Phone Company owns the CO,
    where the CO is, and how far it is from your customer's premise
    using our
     Map It!  feature.

    You'll also find all of the exchanges in that Central Office (the actual CO switch could have many exchanges, allowing it to go over 10,000 phone numbers), and find all of the other COs (colocated) at that address (there could be several).

    Keep in mind that with the advent of Portability, there is no way to tell whether a particular phone number has been ported to another Phone Company without asking your customer (if they know!). You could try dialing 0 for the Operator, but it seems like most are now in India, and don't know who they're answering the line for (they just say they're the Operator).

    If you use the local Phone Company's 1KC Tone on a phone number that's been ported to another Phone Company's switch, the readings probably won't be accurate. You'll need the 1KC Tone phone number in the CLEC's switch.

    We need your local Test Numbers!

    Our database will now list Test Numbers for each switch (1KC Tone and Silent Termination), when we have that information. If you know the test numbers for some of the COs in your area, you can look up that CO, and then enter the information into a form. We'll test them (we don't want to keep calling someone's Grandmother!), and put them in the list within a day or two.

    Since the database lists each CO individually, we need the information on specific COs. Although we can try to put general notes in the listing that will apply to an entire city, state or area code, the most useful information is specific test numbers for a particular CO. At this point, we don't have a lot of test numbers, but we're hoping that will change quickly!

    At most COs, the 1KC Tone is always the exchange code plus a particular last four digits. In the Chicago area, 9996 and 9940 are popular for the 1KC tone, and 9939 or 9995 for Silent Termination. 9997 or some other number is used to open a circuit automatically for a few minutes from the CO for testing in the field (to remove talk battery so you can test with a Kick Meter or Sidekick).

    If you know the common four digit station numbers that a particular Phone Company uses, you may be able to figure out the test number you need by trying those four digits with all the exchanges shown for that CO in CO Lookup (like XXX-9996). Since there are usually several exchanges working out of larger COs, the test numbers will only be on one of the exchanges.

    As an example, if you do a CO Lookup on the 630-295 exchange, you'll find that there are quite a few exchanges working out of that CO (they all have the same CLLI code). Neither 630-295-9996 or 630-295-9940 give you a 1KC Tone, but if you try each of the exchange codes in that CO, when you get to 630-980 you'll find that 630-980-9940 gives your a 1KC Tone.

    Note that on the list of exchanges working out of the same CO, there can be more than one area code in a Central Office. In the case of the CO that has the 630-295 exchange, there are several 847 area code exchanges. This is usually the result of area code splits, where the line between the two area codes went right through the area where a single Central Office served several cities.
