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.
Table 4-33 CD-4COTA Maximum Upgrade Capacities provides the
maximum capacities for the 4COIU blades when they are upgraded.

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.
