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 3810
Plus and 3820Plus
modems, 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
two-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.
