be software-configured. System configuration on a power-up can be accomplished with
the System Configuration (SC) command. Refer to Chapter 4. Configuration and
Operation for more information on the SC command.
T1 Interfaces
The two types of T1 interface that can be used in a D/I Mux III system include the Dual DSX-1
Interface, which transmits and receives a basic DSX-1 signal, and the Dual CSU Interface which
allows the D/I Mux III to perform the functions of a Channel Service Unit (CSU).
