IMUX 2000 T1/E1

April 2007
Designed specifically for the unique need of the harsh substation
environments, the IMUX 2000 T1/E1 Multiplexer incorporates spe-
cial design characteristics which allow it to meet ANSI / IEEE / IEC
standards for operation in harsh environments (RFI, SWC, EMI
and Fast Transient). The Drop-and-Insert through delay is less
than 25 microseconds, including the fiber heads (excluding the
communications medium). Along with the minimal through delay,
a software programmable Fast Reframing channel is available to
allow the multiplexer to reframe in less than 1 millisecond. The
DS0 squelching (patent pending) capability allows the Common
Logic Module to squelch (turn off) the output of a channel module
in the Multiplexer upon loss of synchronization. This feature pro-
vides security against false tripping on 4-wire analog transfer trip
channels and older digital equipment (with limited error checking).
These features in the IMUX 2000 T1/E1 Multiplexer, address the
critical time issues associated with protective relaying, making it
ideal to be used in the electric power utilities industry. In addition,
the multiplexer has the Transfer Trip and Current Differential inter-
faces required for the utility market.
With the increasing demand for faster, more efficient ways to man-
age the flow of traffic, customers need a communication infra-
structure that allows the system to advance as the technology
develops. That is why the IMUX 2000 T1/E1 Multiplexer, with its
unique harsh environments design, is the preferred choice of com-
munication for the Transportation Industry. The IMUX 2000 T1/
E1 multiplexer is designed to be used as part of a large traffic
management system working in conjunction with higher bandwidth
SONET/SDH networks or in stand-alone T1/E1 networks.
Applications for the product include: roadside signal acquisition
and transmission from vehicle loop detectors, compressed digital
video, camera control, toll collection, status and alarm reporting,
tunnel ventilation control, and voice and data traffic signal control
systems. The compact and robust design and the ability to work
under harsh conditions makes the IMUX 2000 T1/E1 multiplexer
the best multiplexer for transportation applications. The network
management software provides ease of maintenance with Win-
dows™ based GUI software. The optional SNMP based man-
agement reporting software can be used when integrated as part
of a larger enterprise system.
