Local Access 6
Figure 6-1 shows the system has two EIA-232-D compatible interfaces for a CIT.
The front access interface is configured as data communications equipment
(DCE) for direct CIT access (CIT 1). The rear access CIT interface (CIT 2) is
configured as data terminal equipment (DTE) to allow a permanent modem
connection without requiring a null modem. However, a null modem is required
when connecting a CIT directly to the rear access DTE interface. CIT access via a
modem connection is identical to local CIT access.
