Overview
This chapter contains information for installing your
E1 DSU/CSU. It includes application examples, cabling,
and power-up information.
Application Examples
The E1 DSU/CSU is designed to provide an interface
between the E1 digital network and the customer premises
equipment. The E1 DSU/CSU is connected to the
customer premises equipment through one of the
synchronous data ports (POR
T
s 1–
4) or the DTE
Drop/Insert port (DTE). It is connected to the network
through the Network interface (NETWORK). The most
common applications for the E1 DSU/CSU are:
• Point-to-Point LAN interconnection (Figure 2-1).
•
Shared access to network-based services
(Figure 2-2).
• Fractional E1 network applications (Figure 2-3).
• W
ireless/DACS (Digital Access and Cross-connect
System) applications (Figure 2-4).
Both voice and data applications are supported.
