Overview
This chapter contains information for installing your
standalone DSU/CSU. It includes application examples,
cabling, and power-up information.
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 the synchronous data port (PORT 1). It
is connected to the T1 digital network through the
network interface. Some common applications for the
DSU/CSU are:
• Point-to-Point LAN interconnection (Figure 2-1).
• Fractional T1 network applications (Figure 2-2).
