The CD-4COTB blade 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

Install the CD-4COTB blade into an available slot in the chassis.
(Refer to Figure 4-26 CD-4COTB Blade on page 4-66
the blade.)
 If the PZ-4COTF is to be used, install this prior to inserting the CD-4COTB
blade into the chassis.
When using the CD-4COTB blade for ground
start trunks, the PBX ground must be
connected as described in
the SV8100 Chassis,
Grounding on 19" Chassis on page 3-18
trunks to function correctly.
The trunk ports are polarity sensitive. Be
careful when wiring the trunks.
When connecting the RJ-61 cables to the
CD-4COTB blades, 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.
