2.5 Configuration 4 - PBX to PBX
Configuration 4 is a data/voice/fax configuration that uses two DataTalkers to link two PBXs.
Using a single ISDN composite link, they connect a minicomputer and a PBX E&M trunk at the
local site to a remote PC on the data part of the network and a second PBX E&M trunk on the
voice/fax channel. The configuration is shown in Figure 2-4.

Figure 2-4. PBX to PBX Configuration
At both the local and the remote sites, connect the DATA/COMMAND connector on the
DataTalker to an asynchronous port on the computer; connect the DSU/TA DIGITAL jack on the
DataTalker to the jack for the ISDN service; and connect the VOICE/FAX CHANNEL 1 E&M jack
on the DataTalker to a PBX E&M trunk connector. When you are making an E&M connection,
you should also run a ground wire from the ground connector on back of the DataTalker or the
RackTalker rack to a ground connection on the PBX.
Before you install the DataTalkers, you must configure them. To configure a DataTalker, place
DIP switch position 3 in the down (closed) position and connect a command port device such as
a terminal or a PC to the DATA/COMMAND connector on the back of the DataTalker. Turn on the
DataTalker and PC and run your communications software in terminal mode. (Set it for direct
connection at a serial port speed of 19,200 bps or slower.) Press the ENTER key to establish
communications with DataTalker. The Main Menu will appear.
The Main Menu provides access to a series of configuration menus providing simple and
complete configuration information for each aspect of the DataTalker. From the Main Menu, you
can configure the unit, display statistics, reset various functions within the MMV, and run
diagnostic tests:
