PA-8LCBR
Line Circuit
1. General Function
The PA-8LCBR circuit card provides an interface between a maximum of eight analog voice terminals and
the system with a range of 1200 (0hm) inclusive of terminal resistance. This card 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
each channel. This card can be used for Caller ID service.
