Line Circuit
1. General Function
The PA-16LCBJ-B circuit card, which is exclusively used in a µ-law system, provides an interface between
a maximum of 16 analog terminals and the system with a range of 600 (0hm) 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.
