1. General Function 
The PA-16LCBY circuit card provides an interface between a maximum of 16 analog voice terminals and
the system with a range of 1200 (Ohm) inclusive of terminal resistance. This card also can send “Stutter
Dial Tone,” which is not a continuous tone, to an associated terminal which has no Message Waiting Lamp
(MWL) instead of activating the MWL if required. In addition, polarity reverse function...
