configuration options must be set using either the
Diagnostic Control Panel (DCP) or the AT command set.
This chapter describes how to access and use the
Configure branch of the Top-Level menu via the DCP.

The Configure branch accesses the Edit Area which is

a work space where you view and change any
configuration options (straps). These configuration
options are loaded to the Edit Area from one of five
configuration option areas: Active (Operating),
Active (Saved), Customer 1, Customer 2, or Factory.

•

Active (Operating) is a configuration area
containing configuration options currently used by
the modem. When the modem is powered on or
when a save is performed, the contents of Active
(Saved) are loaded into Active (Operating). Any
changes made using AT commands directly affect
this configuration area.

•

Active (Saved) is a read from and write to
configuration option area containing the most
recently saved changes made to any configuration
options. In the event of power loss or reset, the
modem retrieves these settings from nonvolatile
memory.

•

Customer 1 and Customer 2 are two additional
read and write (changeable) configuration areas
where you can create and store additional
configurations for specific applications.

•

Factory is a read-only (unchangeable)
configuration area containing six sets of predefined
configuration options labeled Async Dial, Sync
Dial, Sync Leased (Answer/Originate), UNIX
Dial, Cellular (Mobile), and Cellular (PSTN).
These sets contain the most commonly used
configuration options for modems installed in these
hardware environments, and give you a head start
in configuring your modem. Factory default
settings are listed in Appendix G.

NOTE

If you are using AT commands,
a period of time can exist in
which the contents of Active
(Operating) and Active (Saved)
differ. Once you issue an
AT&W0 (write) command,
however, the two storage areas
are identical.
