Introduction
The DIU2U (Digital Interface Unit 2 Universal) trunk module connects two digital trunks to Hi-
Path 3800 and in this way provides two primary rate interfaces (PRI) ISDN via T1 interfaces.
Connection types

The fiber optic cable is only connected via the front panel. The opto-electronic converter
AMOM must be used to connect a fiber optic cable to the 15-pin Sub-D jacks on the front
panel.

The copper cable is connected to T1-CSU (Customer Service Unit) or DSU (Data Service
Unit) via the adapter cable (C39195-A7269-B625) shown in Figure 3-41.
