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:
