Connection for COIDB Daughter Board
The 4COIU 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.
When using the CD-4COTB blade for ground
start trunks, the PBX ground must be
connected as described in
the SV8100 Chassis
Chassis Grounding on page 4-39
will not 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.
