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.
The trunk ports are polarity sensitive. Be
careful when wiring the trunks.
When connecting the RJ-61 cables to the
CD-4COTA blades, note the position of the
Power Failure connector (CN3). Do not
confuse this connector as the trunk connector
(CN2).
Do not wire an RJ-11 directly to the
CD-4COTA interface. Use the appropriate
RJ-61 wiring when connecting to the
CD-4COTA.
