The Viking model LLA-4 provides four 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 four low talk battery voltage or weak ringing analog lines into standard 48V lines with powerful 20HZ sine wave ring signals.
The LLA-4 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 an earth ground reference for the regenerated lines.
The long loop adapter requires no programming, and can be used as a direct replacement for the discontinued Proctor model 46224 long loop adapter.
