Overview
The
standalone 3810
Plus modem (Figure 2-1) is
capable of either dial or 4-wire/2-wire leased-line
operation; the standalone 3820Plus modem (Figure 2-1) is
capable of either dial or 2-wire leased-line operation.
Either modem is controlled using AT commands or the
diagnostic control panel (DCP). The DCP consists of an
LCD which displays selections, three function keys and
four directional keys which allow you to maneuver and
choose DCP selections, and a row of 13 LED status
indicators which display modem activity. For a better
understanding of DCP operation, refer to Chapter 3, Front
Panel Operation.
The rear of the 3810Plus modem contains an ON/Off
power switch, a low voltage power connector, an 8-pin
modular jack for leased-line connection, an 8-pin modular
jack for dial-line connection, a 4-pin modular jack for
network management, and a DB-25-S DTE connector.
The 3820Plus
has a single 8-pin modular jack which is
used for leased-line or dial-line connection.
