OVERVIEW OF APPLICATIONS
This section summarizes a typical application of the
AK61584 in various environments, and discusses
what AK61584 options would normally be selected
in that application. See Figure 8.
AT&T 62411 Customer Premises Application
AT&T 62411 applies at the T1 interface between
the customer premises and the carrier, and must be
implemented by the customer premises equipment.
