Using The Modem; Incoming Calls; Outgoing Calls - Liebert 300 series Installation, Operaton & Maintenance Manual

The modem option
communicate with the "outside world" over any
standard analog telephone line. (Note that some
in-house commercial phone systems use digital
telephone lines designed to work with
nonstandard telephone equipment. The modem
in the UPS will not be able to communicate over
these lines.)
There are several ways to communicate with the
UPS using the modem; they are detailed
separately in the following sections:
Incoming calls
The UPS will answer incoming calls from
another modem any time the UPS control logic
has power, regardless of whether the load is on
or off. Almost any ANSI compatible terminal
equipped with a modem can be used as a remote
monitoring and/or control station.
Alternatively, you can use a computer (IBM-PC
or compatible, Macintosh, etc.) equipped with a
modem and communication software as a
remote station. Most PC communication
software programs provide an ANSI terminal
emulation mode which will work with the UPS.
Programs such as Procomm, Tel& and the
Microsoft Windows TEBM.EXE have all been
used successfully as remote monitoring stations.
Calling the UPS is no different than calling an
online service such as CompuServe, or a
computer bulletin board. The UPS is the host,
terminal (or PC) is the remote.
Because of the wide variety of terminals and
communication software products available, it is
not possible to provide step-by-step instructions

that some PC software
programs will work using
terminal emulation protocols.
Many protocols are based on the
basic ANSI set. Feel free to
experiment, you can't hurt the
UPS or the comuuter.
Configuring the UPS to Accept

Incoming Calls

Before the UPS will answer any incoming calls.
the Modem Mode setting must be set to either
IN or BOTH (see "Setting the Modem Mode"
on page 5-9). By default, the Modem Mode is set
to OFF.

Outgoing Calls

The UPS can be configured to dial up to 2
numbers. Either of these numbers can be a
pager or a modem. The UPS uses a priority
system based on the settings of the Modem
Mode and Call #2 Mode values (see "Setting
the Modem Mode" on page 5-9 when placing
the calls).
