Station connection
The first 12 pairs on each amphenol are station ports (either 12 digital stations on the 612 or
DLC12 card or eight digital stations and four analog ports on the 684 port card).
All stations are connected using a single pair. Each port position is pre-numbered and fixed as
indicated in the 66 Block Wiring Diagram shown for each port card type.
Note:
The station runs can be up to 1,000 ft.
Digital stations
The digital station wiring is not polarity-sensitive. Only one phone can be connected per
digital port.
Analog ports
The analog ports do not require that tip-and-ring polarity be observed. The analog ports can be
used for 2500 type sets or for devices such as fax machines, modems, etc., that can be connected
via a normal tip-and-ring pair. Each analog port will support only a single analog device.
Station Numbering Plan
Each port card has 12 station interfaces. The station numbering plan starts with the first pair on the
first port card as 100 and ends at 183 on the 7th port card.
