2.2 Installing Station Boards In The Equipment Cabinet
1. Normally you should first disconnect the optional battery back-up assembly from the main cabinet power
supply and then disconnect the AC power cord from the AC outlet; however, when necessary, you can install
a station board in an operating system. If you must do this, connect one end of a standard telephone handset
coil cord to the precharge port on the power supply. During step 5, you will connect the other end of this coil
cord to the precharge...

3.0 Connecting The Stations
Connections between the telephone stations and the common equipment station boards are typically via type
66M-xx connector blocks that are cable connected to 50-pin male connectors on the station boards.
The American Wire Gauge (AWG) size of the station wiring determines the maximum distance allowed from the
common equipment to the stations. The following chart details this relationship.

3.3 Detailing Station Call Announce Parameters
The DXP Plus systems place no limits (other that the distance constraints stated previously) on telephone
placement and arrangement within the system; however, when placing telephones that require call announcing
capability, consider the parameters detailed in this call announce matrix table.

How logical number and physical location relate to one another
The logical number of a station or line corresponds to its relationship to other stations or lines in the system but is
not dependent upon the board’s placement in the cabinet. The physical location of a station or line corresponds to
the order of the system’s board slots. The main cabinet contains slots 1–9, the upper expansion cabinet contains
slots 10–20, and the lower expansion cabinet contains slots 21–30. Therefore, even if the first...

4.0 Installing Subdued Off-Hook Voice Announce
Wiring For Analog Stations
An analog multiline telephone has subdued off-hook voice announce (SOHVA) capability built into it. This
telephone contains a 6-position, 3-pair station jack for SOHVA connection.
To enable SOHVA as a system feature for analog stations,
4you must use 6-wire, twisted-pair house cable to connect two data-paired station ports to
a 625A2-6 station jack,
4you must connect the SOHVA-capable analog multiline telephone to the 625A2-6...
