Multiple phones
I am considering cutting off my landline service and running a dedicated system with MJ running in to a wall jack so I can use it anywhere in my house. The question I have is, my house is rather large and there is about 20 or so phones plugged in all over the place, is it possible to overload MJ?
even on a regular phone line you can only use a max of six phones,it takes 90 volts to ring a phone and 45 to use the phone,i have no idea but i would say a max of 2 phones will work if that.
LONG LOOP ADAPTERS
Ring Voltage Booster II Loop Current Booster
BOOST Loop Current and Ring Voltage
Our Loop Current Booster and Ring Voltage Booster II™ 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 or low talk battery / loop current. It's unlikely you'll need both, unless the pair is very long or the analog station port is particularly weak.
Because you only need to purchase the Booster that fixes the particular problem on the line, you'll save money.
The combination of both the Loop Current Booster and Ring Voltage Booster™ 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.
It's very difficult and expensive to amplify a 2 wire phone line if the volume is low. Our Boosters won't increase how loud the line is. More details on Circuit Loss are in our Loop Current and Circuit Loss Tech Bulletin.
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 on measuring AC ring voltage in our in our Ring Voltage Tech Bulletin.
RING VOLTAGE BOOSTER II™
Ring Voltage Booster II
NEW! 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!
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.

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�t 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�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™ 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.
Part Number: KIT8L Price: $99.95 ||| 3+ Price: $89.95

Re: Multiple phones
Why do you need so many phones? i live in a ~4500 sq foot house and we used to have a phone in all rooms (6) + 4 downstairs + 2 in the basement and 1 in the attic.... even that was way to much.. now have one phone per floor (2 on 2nd floor though) and its more then enough.napalm-fi wrote:I am considering cutting off my landline service and running a dedicated system with MJ running in to a wall jack so I can use it anywhere in my house.

Re: Multiple phones
Well, I cant disagree with you I probably could do with less phones but the house is considerably larger then 4500 sq feet with three stories and 25 rooms so I could never do with only one or two phones. So im guessing the only way to make this possible is with expensive boosters.kumar wrote:Why do you need so many phones? i live in a ~4500 sq foot house and we used to have a phone in all rooms (6) + 4 downstairs + 2 in the basement and 1 in the attic.... even that was way to much.. now have one phone per floor (2 on 2nd floor though) and its more then enough.napalm-fi wrote:I am considering cutting off my landline service and running a dedicated system with MJ running in to a wall jack so I can use it anywhere in my house.

With 20 telephones in 25 rooms of a 4500ft+ home, you need an EKTS (electronic key telephone system), not a ring booster. My preference is for Norstar systems, mostly because they require only one pair to each extension, but others have other preferences.
And, with such a large home you need to reconsider dropping POTS service. After all, MJ (or any other VoIP service) will not be compatible with your alarm panel.
