Information: 715-386-8861
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 requires no
programming, and can be used as a direct
replacement for the discontinued Proctor
model 46222 long loop adapter.

IMPORTANT: Electronic devices are susceptible to lightning and power station electrical surges
from both the AC outlet and the telephone line. It is recommended that a surge protector be
installed to protect against such surges.
Installation
* Note: To increase surge protection, and to give the long loop run an earth ground reference, fasten
a wire from the screw terminal to Earth Ground (grounding rod, water pipe, etc.).
Switch 1 Description
OFF Detects typical 20Hz AC ringing (factory default)
ON
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 Description
OFF OFF Ring OFF - Incoming ringing is not passed through the unit.
OFF ON The outgoing ring signal will “follow” the cadence of the incoming ring signal.
ON OFF A double ring signal will be “filled in” so the outgoing ring will look like one
longer ring signal (factory default).
ON ON
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.
Programming
There are three DIP switches on the LLA-1 printed circuit board to allow for different ringing protocols.

Operation
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 on-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 on-hook, the LLA-1 will release the system line.
