Line Circuit
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 is provided for 16
channels on this card. The card can be used for Caller ID service. This is a -48V card.

Flashing1)
 Ringing signal is being transmitted. Busy Lamp keeps flashing 
in synchronizing with on/off of the ringing signal.
2) Dial pulses are being received. While dial pulses from a line are 
being received, Busy Lamp keeps flashing in synchronizing 
with the dial pulses coming from the line.
3) Line is in make-busy state.
Busy Lamp keeps flashing at 60 ipm.
