• Convert an analog KSU/PABX station to a
standard voltage OPX
• Provides 48 VDC talk battery
• Provides 20 HZ, 10 REN sine wave ringing
• Passes Caller ID information
• Passes hook switch flash
• DTMF
and pulse
dialing compatible
• Passes CPC signals
• Electrically isolates PABX station from
extended loop
• Provides additional lightning and surge
protection
• Selectable ring protocols
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 fea-
tures, 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.

• Turn a standard station into an on-premise or
off-premise extension (OPX)
• Give any low voltage line or station from an ISDN
terminal, KSU, PABX, etc. the talk battery and
ringing power of a standard C.O. line
• Convert a polarity reversal DC ring signaling line
to a typical 20Hz AC ringing line
