PA-4CSIC (CSINT)  : ZT (Zone Transceiver) Interface
1. General Functions
This circuit card is designed to provide the ISDN S interface to the Zone Transceiver (ZT).
Specifications and functions of this circuit card are shown below.
 A maximum of four ZTs can be accommodated in one 4CSIC circuit card.
 Interface with ZTs is based on the ISDN standard interface, though the multi-point connection of the
ZTs is not available.
