Diagnostic Control Panel
The Diagnostic Control Panel (DCP) is the user interface to the modem. It provides a
2-line, 32-character liquid crystal display (LCD), a keypad, speaker grill, and status
indicators.
A Shared DCP (SDCP) is used to manage carrier-mounted 3811Plus modems. The
Select key is used to connect the SDCP to a modem or other device in a specific
carrier and slot location. Press the Select key, then enter the modem carrier (1–8) and
slot (1–16) numbers. Once the modem is selected, operation of the SDCP is the same
as for the standalone DCP.
