CONNECTING BLOCKS
Working With DDK Connectors
The system uses DDK-type connectors for extensions,
trunks and optional equipment. Using the optional DDK
Installation Cables (4-pin station cable=P/N 82490, 2-pin
C.O. line cable=P/N 82492) makes it easy to connect the
PCBs to standard 66M1-50 connecting blocks. The cables
available for the system are for CO lines (one-pair), keysets
(2-pair), and auxiliary options (one-pair). If desired, sepa-
rate DDK connectors without cable can be purchased. In
general,...

Punching Down a DDK Installation Cable
The DDK Installation Cables have 4-pin DDK connectors
installed on one end and are unterminated on the other. 
1.For each 66M1-50 block, punch down the DDK
Installation Cable in standard color-code order.
Refer to Figure 3-3 if you need help with the color
code.
2.  Make all wire connections required for any optional
cards installed.
