Modem Communicator
The Modem Communicator is a two-way local rail module that performs a variety of
off-premise communications functions for the EST3 system unavailable on any
other system. The module has provisions for supervising two loop-start telephone
lines. It features a modular jack for telephone line connections, as well as database
download from a PC. The Modcom’s configuration and firmware can also be updated
from any network node.
Modcom series modules occupy a single local rail space and can be mounted in any
node on the network. Any EST3 Control/Display module can be mounted on the face
of a Modcom series module. Power for the Modcom is supplied by the EST3 system
supply.
The Modcom provides an enhanced level of survivability in the event of a network
CPU failure by notifying the Central Monitoring Station of the failure and entering a
degraded mode of operation. In degraded mode, the Modcom can transmit a default
fire alarm message during a fire alarm condition.
Two versions of the Modcom are available:
3-MODCOM - This internal modem is a V.32bis 14.4K baud full duplex modem. The
modem permits the remote upload and download of system data via a telephone
line.
3-MODCOMP – In addition to all modem and dialer (DACT) functions of the 3-MODCOM,
the 3-MODCOMP can dial directly into paging systems using Telelocator Alphanu-
meric Protocol (TAP). Alphanumeric system data can be sent to a single pager or
groups of pagers. Some pager services can
forward messages via e-mail and Fax.
Each Modcom can buffer up to 500 events in its event queue. It reviews all
active events in the queue and identifies the highest prior-
ity event and dials the associated receiver. The Modcom then
identifies all other events in the queue that are destined to
the same receiver as the highest priority event. All event
information for that receiver is then transmitted. The next
high priority event is identified and the process repeated.
The Modcom series has been designed for installation on the same phone
lines with other devices such as faxes and answering machines. The module
makes its first dial out attempt on either of the two phone lines that is not in
use. This prevents unnecessary interruption of calls in progress by the line
seizure relays. In the event that both lines are busy, the module seizes one of
the busy lines. A fixed DACT testing time can be set at an off-hour, e.g. 2:00am,
again minimizing interruptions.
The answering machine override feature permits Modcom modules to be
installed on a standard telephone line. The Modcom series also has the ability
to detect Type 2 and Type 3 distinctive ringing patterns, permitting it to share
its phone lines with other devices and still have a unique phone number for
incoming calls.
