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 (PORTs 1– 4) or the DTE
