DCP Configuration
Overview
After installing a 391x Series modem, its software 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 a power cycle 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 Sync Leased, Async Leased, TMp (Trellis Multipoint),
Async Dial, Sync Dial, and UNIX Dial. If Sync Leased or Async Leased is selected, you
must choose either Answer or Originate mode. If TMp is selected, you must choose either
Control or Trib (Tributary) mode. These sets contain the most commonly used
configurations options for modems installed into these hardware environments. These
predefined configuration options are intended to give you a head start and only require a
minimum of changes to the default settings. Factory default settings are listed in
Appendix F, Default Configuration Options.
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.
