Long Loop Adapter
(Off Premise Extensions)
2 1 S T C E N T U RY
May 6, 2005
Extend Analog PABX Station Loop Length
to 30,000 Feet
• Direct Replacement for Proctor model 46222 Long Loop Adapter
The Viking model LLA-1 provides long line and
off premise extension (OPX) capabilities for
PABX and KSU analog stations, ISDN terminal
adapters, channel banks, etc. The long loop
adapter converts any low talk battery voltage or
weak ringing analog line into a standard 48V
line with powerful 20HZ sine wave ring signal.
The LLA-1 is compatible with pulse dialing, touch tone dialing, hook switch flash features, CPC signaling, and Caller ID features. A ground screw terminal allows for
improved surge protection and as a earth ground reference for the regenerated line.
The long loop adapter is easy to install, requires no programming, and can be used as
a direct replacement for the discontinued Proctor model 46222 long loop adapter.

This equipment complies with Part 68 of the FCC rules and the requirements adopted by the ACTA. On the
bottom of this equipment is a label that contains, among other information, a product identifier in the format US:
AAAEQ##TXXXX. If requested, this number must be provided to the telephone company.
This unit is hard wired to the telco service using screw terminals as shown in the installation section.
The FIC for this equipment is OL13C.
The REN is used to determine the number of devices that may be connected to a telephone line. Excessive
REN's on a telephone line may result in the devices not ringing in response to an incoming call. In most but not
all areas, the sum of REN's should not exceed five (5.0). To be certain of the number of devices that may be connected to a line, as determined by the total REN's, contact the local telephone company. For products approved
after July 23, 2002, the REN for this product is part of the product identifier that has the format: US:
AAAEQ##TXXXX. The digits represented by the ## are the REN without a decimal point (e.g., 03 is a REN of
0.3). For earlier products, the REN is separately shown on the label.
If this equipment causes harm to the telephone network, the telephone company will notify you in advance
that temporary discontinuance of service may be required. But if advance notice isn't practical, the telephone
company will notify the customer as soon as possible. Also, you will be advised of your right to file a complaint
with the FCC if you believe it is necessary.
The telephone company may make changes in its facilities, equipment, operations or procedures that could
affect the operation of the equipment. If this happens the telephone company will provide advance notice in order
for you to make necessary modifications to maintain uninterrupted service.
If trouble is experienced with this equipment, for repair or warranty information, please contact Viking
Electronics, 715-386-8666, If the equipment is causing harm to the telephone network, the telephone company may request that you disconnect the equipment until the problem is resolved.
This equipment is not user repairable.
Connection to party line service is subject to state tariffs. Contact the state public utility commission, public
service commission or corporation commission for information.
If your home has specially wired alarm equipment connected to the telephone line, ensure the installation of
this equipment does not disable your alarm equipment. If you have questions about what will disable alarm
equipment, consult your telephone company or qualified installer.
It is recommended that the customer install an AC surge arrester in the AC outlet to which this device is connected. This is to avoid damaging the equipment caused by local lightning strikes and other electrical surges.
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference
when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the interference at his own expense.

There are three DIP switches on the LLA-1 printed circuit board to allow for different ringing protocols.
Switch 1
Internal View of the LLA-1
Detects typical 20Hz AC ringing (factory default)
Detects polarity reversal DC ring signaling.
Note: This mode is polarity sensitive. If connected in
reverse polarity, the LLA-1 will ring continuously. See the
diagram at the right for proper polarity.
Switch 2
Switch 3
Ring OFF - Incoming ringing is not passed through the unit.
The outgoing ring signal will “follow” the cadence of the incoming ring signal.
A double ring signal will be “filled in” so the outgoing ring will
look like one longer ring signal (factory default).
The outgoing ring signal will be “forced” to a full 2 seconds, no
matter what the incoming ring signal is. Note: Not recommended if Caller ID is being used.
DIP Switches
(shown in factory
default positions)
When the LLA-1 is sitting in the idle state, it provides -48VDC talk battery out the long loop screw terminals for the OPX
phones (or trunk input).
When the OPX phone goes off hook, the system line is seized, talk path is opened, and system dial tone is passed through
the LLA-1 to the OPX phone. Touch Tone or 10pps Pulse digits can now be dialed. If the system provides a CPC signal, it
will be passed through the LLA-1 to the OPX phone. When the OPX phone goes back in hook, the LLA-1 will release the
system line.
When ringing is detected from the system, the LLA-1's internal sine wave ring generator produces a 20Hz 105V AC ring
signal to the OPX phone. Re-ring cadence is selectable (see programming). If Caller ID data is received after the first ring,
it will be amplified and passed on to the OPX phone. When the OPX phone answers, the LLA-1 will answer the system line,
and provide talk path through the unit. If the system provides a CPC signal, it will be passed through the LLA-1 to the OPX
phone. When the OPX phone goes back in hook, the LLA-1 will release the system line.
The front panel LEDs operate as follows:
PWR LED - Lights steady when the unit is powered up, and winks off to show incoming ring signal detection.
RING LED - Lights to show re-ring cadence going out of the long loop to the phone.
IN USE LED - Lights when the phone is off-hook to show the line is in use.
CPC LED - Lights to show a CPC signal is detected and being re-generated out the long loop to the phone.
