2.2  DESCRIPTION

The Model 1004ABRC high speed, multipoint short range modem

rack card is a 

dual rack card incorporating two short range modems.

Both units support asynchronous data rates to 115.2 Kbps over 1 or 2
twisted pairs and support distances to 4000 feet (19 AWG @19.2
kbps). In addition, Model 1004ABRC’s unique data control feature
allows it to be used in multi-point environments without the use of hard-
ware control signals.

The Model 1004ABRC can handle up to 50 terminal drops in a

multipoint polling environment. Using transitions on the data line to
handle line contention, the Model 1004ABRC can be used in environ-
ments that need multi-port bus contention, but do not have control sig-
nals such as RTS or DTR. The Model 1004ABRC may be configured
for high or low impedance operation, and the unit can operate with or
without “echo”.

Filling one function card slot on Patton’s Model 1000R16 rack

chassis, the Model 1004ABRC is available with RJ-11 or RJ-45 rear
interface cards. For workgroup and desktop communications, the
Model 1004ABRC also fits in Patton’s 2, 4 and 8 slot ClusterBoxes™.
The combination of rack mount, ClusterBox™ and self-powered units
provides a completely integrated  “networking” solution.

NOTE:

Packages received without an RMA number will not be

accepted.
