PA-8RSTY

Register Sender Trunk

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.

This figure shows “Register Sender” function as an example.
