Simultaneous Voice And Data At Analog Stations - AT&T Merlin II Feature Module 2 Data Communications Manual

Simultaneous Voice and Data at Analog Stations

The Master Planning Form shows which analog stations should have
simultaneous voice and data capability. The numbers of the station jacks to
which each of these stations should be connected are boxed on the form.
Note that the jack pairs are consecutively numbered jacks on the same
4-Line/8-Analog Voice Terminal (408) Module or 8-Analog Voice Terminal
(008) Module. Each pair includes an odd-numbered jack and the jack with
the next higher even number, such as jacks 15 and 16.
The fundamental wiring scheme that joins the required pairs
into one 4-pair cord is indicated in the wiring diagram of Figure 3-5.

Odd
At some point between the voice terminal and the odd/even jack pair, the
voice pair (5 and 4) from the even jack is joined with the other three pairs (4
to 8, 5 to 7) to make a complete 4-pair connection to the voice terminal.
To equip an analog station for simultaneous voice and data communication,
you need the following:
Analog voice terminal
General Purpose Adapter (GPA)
AT&T DATAPHONE
modular connection capability
Data terminal or computer
Cables and connectors for connecting the components
The connectivity diagram in Figure 3-6 shows a typical configuration for an
anaIog station with simulta.neous voice and data capability.
