Overview
This chapter contains information for installing your standalone DSU/CSU. It
includes application examples, cabling, and power-up information.
NOTE:
Installation instructions for the carrier-mounted DSU/CSU are located in the
ACCULINK 3151 CSU and 3161 DSU/CSU General Information Guide
and
the COMSPHERE 3000 Series Carrier Installation Manual .
Application Examples
The DSU/CSU acts as an interface between the T1 digital network and the
customer’s equipment.
The DSU/CSU is connected to the customer’s equipment through one of the
synchronous data ports (PORTs 1– 4) or the DTE Drop/Insert (DSX-1) interface. It
is connected to the T1 digital network through the network interface.
NOTE:
The DTE Drop/Insert (DSX-1) interface is only available on 2-port and 4-port
DSU/CSUs.
Some common applications for the DSU/CSU are:
„
Point-to-Point LAN interconnection ( Figure 2-1, Point-to-Point Application
Example ).
„
Shared access to network-based services ( Figure 2-2, Shared Access
Application Example ).
„
Fractional T1 network applications ( Figure 2-3, Fractional T1 Application
Example ).
