PA-4CSID (CSINT)  : ZT (Zone Transceiver) Interface
1. General Functions
This card is a line circuit card which accommodates Zone Transceivers (ZTs) via the ISDN U interface. ZTs
are to be connected using NT1.
The main specifications and functions of this circuit card are shown below.
 A maximum number of four ZTs can be accommodated in one circuit card.
 Interface with the NT1 is based on the standard ISDN interface. (U reference-point Echo Canceller
method.
ANSI TI.601, Q.921 interface)
 Two B channels of each 32 kbps can be used in 2B+D with the total speed of 64 kbps.
 Sealing current (Maximum 15mA) can be supplied to protect cables from rusting.
 Equipped with ADPCM which enables the B-channel bit rate to change. (TSW-side: 64 kbps, ZT side:
32 kbps)

Note 1:
PAD control is shown below. Note that Echo Canceller, PAD 3 and PAD 4 are bypassed when the MODE
switch is set to “0”.
Note 2:Regarding speech communication, PAD values set on SW12-1 through SW12-6 are applied. In the other
cases (ex. data communication), PAD values are set according to the order of CPU.
