The connectors 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-

8COTAH 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-

8COTAH interface. Use the appropriate RJ-61

wiring when connecting to the CD-8COTAH.
