Designing for AT&T 62411
For additional information on the requirements of
AT&T 62411 and the design of an appropriate sys-
tem synchronizer, refer to the Crystal Semiconduc-
tor Application Notes "AT&T 62411 Design
Considerations - Jitter and Synchronization" and
"Jitter Testing Procedures for Compliance with
AT&T 62411."
13.7
Line Protection
Secondary protection components can be added to
the line interface circuitry to provide lightning
surge and AC power-cross immunity. For addition-
al information on the different electrical safety
standards and specific application circuit recom-
mendations, refer to the Crystal Semiconductor
Application Note "Secondary Line Protection for
T1 and E1 Line Cards."

Loop Selection Equations
The following equations indicate the different
states that various inputs have to assume to invoke
the various loopback functions available in the de-
vice.
...... RLOOP1 =TAOS1.LLOOP.RLOOP1
...... RLOOP2 =TAOS2.LLOOP.RLOOP2
...... LLOOP11 =LLOOP2.RLOOP2.RLOOP1 +
...... ..............TAOS1.RLOOP1
...... LLOOP12 =LLOOP2.RLOOP2.RLOOP1 +
