DIU 2130 Quick Set-up
Before installing each DIU 2130 and associated DIM, the shelves,
power, controller cards (NCC, SCC, or NCM), and CSUs (NCC, SCC,
DIDCSU, or TAC 2010s) must be installed.
The Access System 2000 allows installation of a DIU 2130 and DIM
in any shelf/slot, except Slot 1 in Shelf 1 of each node—this slot is
reserved for the node controller.
The DIU 2130 is always a DCE device. The external customer data
equipment can be either DCE or DTE.
Installation Do the following before installing the DIU:
• Install all associated Access System 2000 shelves and power
supplies, as outlined in the AS2000: The Basics manual.
• Install and test the CSUs. Be sure all CSUs are configured
properly for operation with the DIUs.
The following CSU configuration options must be set before use
with DIUs:
• DIU Data Bus Assignment
• DIU Timing Mode
Configure the DIU module before connecting its DIM to the
customer data equipment.
Cables The cables required for DIU connection to the customer data
equipment depend on the type of interface selected (RS-449, V.35
or EIA 530) and the data equipment configuration, which can be
either DTE (data terminal equipment) or DCE (data communication
equipment). The DIU 2130 is always in a DCE configuration.
Configuring the
DIU 2130
For this example, an SCC 2020 is used with a DIU 2130 module in
the right side (slot 2) of a Dual-Line Shelf. The SCC 2020 connects
directly to the T1 circuit and provides CSU functionality. The DIU
2130 presents two synchronous serial interfaces for connecting the
Data Terminal Equipment (DTE) and provides DSU functions.
