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,
✔
you must use 6-wire, twisted-pair house cable to connect two data-paired station ports to
a 625A2-6 station jack,
✔
you must connect the SOHVA-capable analog multiline telephone to the 625A2-6 station jack using
a 6-wire line cord,
✔
you must take programming action to configure the station ports to support SOHVA operation.
Make the installation per the following procedure:
1. Identify two data-paired ports on an analog station connector block (identify an odd-numbered port and its
even-numbered counterpart such as ports 103 and 104).
2. Use 6-wire, twisted-pair house cable and make the following connections:
(a) connect pins 3 and 4 (the inside pair) of a 625A2-6 station jack to the voice pair of the odd-numbered
station port.
(b) connect pins 2 and 5 (the outside pair) of the 625A2-6 station jack to the data pair of the odd-numbered
station port,
(c) connect pins 1 and 6 of the 625A2-6 station jack to the voice pair of the even-numbered stration port,
(d) leave the data pair of the even-numbered station port vacant.
3. Using the Telephone Types programming selection from the stations programming menu, program the
odd-numbered station port to support the type of telephone that you will install there. Program the
even-numbered station port as UNDEFINED.
