System Hardware Manual
The PZ-4COTF consumes four trunk ports ranging between ports
001~200. The CN2 connector provides connection to four analog
trunk ports, which are polarity sensitive (tip-to-tip, ring-to-ring).
The power failure circuits (CN3), however, are not polarity sensitive.

Installation

To install the PZ-4COTF
1. Four spacers are included with the PZ-4COTF. Install the
plastic spacers on the CD-4COTB or CD-LTA blade. Make sure
to attach the spacers so that they extend out on the side of the
daughter board which has the CN1 connector.
2. Position the PZ-4COTF CN1 connector over the CN4
connector on the CD-4COTB or CD-LTA. Press the blade and
board together, ensuring the plastic spacers lock in place.
3. Install the PZ-4COTF blade (refer to
PZ-4COTF Daughter Board on page 4-70
When using the PZ-4COTF daughter board for
ground start trunks, the PBX ground must be
connected as described in
the SV8100 Chassis,

trunks to function correctly.
The trunk ports are polarity sensitive. Be
careful when wiring the trunks.
When connecting the RJ-61 cable to the
PZ-4COTF daughter board, note the position
of the Power Failure connector (CN3). Do not
confuse this connector as the trunk connector
(CN2).
Switching from Loop Start to Ground Start is
set in system programming.
Do not wire an RJ-11 directly to the
CD-4COTB interface. Use the appropriate
RJ-61 wiring when connecting to the
CD-4COTB.
