Extend Analog PABX Station
Loop Length to 30,000 Feet
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
Features
• 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

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

Programming There are three DIP switches on the LLA-1 printed circuit board to allow for different ringing protocols. Switch 1 Description Detects typical 20Hz AC ringing (factory default) Detects polarity reversal DC ring signaling.
- Page 3 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.
