The Northern Telecom LOGIC 10 sets could be provided two station cable options:
- NE-D50QE Cord: The "NE" cable, which has a wiring pattern compatible with Northern Telecom equipment
- NE-D50QJ Cord: "WE/ITT" cable, which has a wiring pattern consistent with Western Electric/ITT equipment
For the most part, for Lines 1-5, the pin assignments are the same, and use the familiar wiring
used by e.g. 564 and 2564 sets.
The differences can be seen in the pin assignments for Lines 6-9, and can be seen in the "PLUG" columns
(highlighted in yellow) of these two tables provided directly from the Northern Telecom practices:
