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).

•Shared access to network-based services (Figure 2-2).

•Fractional T1 network applications (Figure 2-3).
