PA-24LCBV
Line Circuit
1. General Function
The PA-24LCBV circuit card provides an interface between a maximum of 24-analog terminals and the
system with a range of 600 (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.
