7 — Connecting to data devices
7.1
Data circuit connections
Data interface modules have one or two circuits that connect to data devices. Each
module connects to its data devices through a plug-in adapter module, called a
personality module. Personality modules are user-changeable, and are installed in
Slot 1 and Slot 2 connectors, located on the rear panel of the unit (Slot 2 is stacked
above Slot 1). Figure 7-1 identifies the data and personality module connectors. For
information on installing personality modules, see section 5.5.
Table 7-1 lists the data interface modules and their corresponding personality
modules. There are two V.35 personality modules, one for each variant of the
V.35 DCM.
