Task 7D: Install a Terminal via 7400A Data Sets
This task describes how to connect a terminal via 7400A Data Sets to Port B (DS
integration only) of the MFB. (This task can also be used for remote connection to
DS or CL integration.)
Refer to Figure 2-10, Connecting a Terminal to the MFB via 7400 Data Sets, when
performing this task.

NOTE:
You may use two 7400A data sets in this configuration. However, because
the 7400B data set is easier to set up and use, it is the one described in this
procedure on the terminal side. (The DEFINITY AUDIX system side of the
configuration requires the 7400A.) If you are using two 7400A data sets,
connect the second 7400A the same as the 7400B, but set the options as
described under
