DIU2U (for U.S. only) 
 

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

Connection types  
 •   Fiber optic cable
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.
 •   Copper cable
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 3-30.
