PA-8RSTY
Register Sender Trunk
1. General Function
The PA-8RSTY circuit card is equipped with eight circuits of Registers and Senders. More specifically, this
card contains Dial Pulse Register (DPR), Push Button Receiver (PBR) for receiving digits from extensions
and/or the associated incoming trunks and Dial Pulse Sender (DPS), PB Signal Sender (PBS) for sending
digits to a distant switching system. In addition, this card has “Register Sender” function, by which inter-
digit pause can be changed and PB signals may be converted to DP signals and vice versa without
intervention of the CPU. The card can be used for caller ID service.
Note:
The PA-8RSTY card requires Series 7400 or later software.
