Front Panel Operation
Overview
This chapter describes how to use the diagnostic
control panel (DCP) of the 3800Plus modem.
Diagnostic Control Panels
There are two types of DCPs: the front panel on the
standalone 3810Plus modem, and the shared diagnostic
control panel (SDCP), an optional feature used with a
3811Plus modem installed in a COMSPHERE 3000
Series Carrier. Both DCPs have a 2-line, 32-character
liquid crystal display (LCD) and keypad through which
Top-Level menu branches are accessed to perform the
following:
• Initiate and disconnect dial operations
• Check modem status
• Set up configuration options
• Initiate diagnostic tests
• Access remote modems through the local modem’s
DCP
The LCD displays the result of any command initiated
using the DCP. Most of these operations can be performed
from an attached asynchronous DTE using the
AT command set.
