CONVERTERS AND CONNECTIVITY
BE-1
Coax-to-Twisted Pair Converter (Balun) for E1
The BE-1 coax-to-twisted pair converter (balun)
enables any E1 equipment with an unbalanced
(coax) interface to operate over a twisted pair
connection instead of over more expensive coax
cables.
The BE-1 enables any E1 or ISDN equipment
with a balanced twisted pair interface to use
existing coaxial cables.
The BE-1 is a miniature, lightweight balun that
operates without AC or DC power and provides
insulation of up to 100V.

4, 8-Channel Programmable Sharing Devices
The RSD digital sharing devices enable any
combination of DCEs and/or DTEs to share a
modem, multiplexer or computer port in a
multipoint environment. RSD-1 supports up to
four DCEs/DTEs; RSD-10 supports up to eight.
They are completely transparent to the system
and the data, and operate with sync or async
equipment. The units generate timing signals
internally or operate with external clocks, either
from the main channel or from subchannel 1.
The main channel broadcasts information to all
subchannels in parallel. Subchannels contend to
transmit to the main channel by activating RTS/
DCD or by data transitions.
The devices can be configured to automatically
disable any channel that stays active for longer
than a preset time and blocks all other
subchannels.
Permanent disabling of a subchannel is possible
by setting the front panel switches.
Installation and configuration of the RSD units
are easy. All necessary crossover connections
are defined internally via a DCE/DTE switch, and
only straight-through cables are used to connect
the modems or terminals to the RSD-1 and
RSD-10. The interfaces are RS-232/V.24 and the
connectors are 25-pin D-type, female.
