1. GENERAL

This practice is an installation and maintenance guide
for the ADTRAN Total Access OC-3 (List 3) Multi-
plexer common module with 28 DS1s and Dual DS3
Add and Drops. The Total Access OC-3 Multiplexer
(OC-3 MUX) is illustrated in Figure 1.

Revision History

This is the initial issue of this practice. Future revisions
will be noted in this subsection.
NOTE
References to common, but differing, param-
eters between the Total Access 3000 and the
Total Access 3010, such as number of slots,
will be conveyed by the convention a/b. The
"a" represents the Total Access 3000
parameter and the "b" represents the Total
Access 3010 parameter. For example, the
differing number of access slots in the two
platforms, 28 for the Total Access 3000 and 22
for the Total Access 3010, would be displayed
"28/22."
