Intraplex® NetXpressLX
Intraplex® NetXpress LX™
IP Audio Multiplexer
Unprecedented Flexibility in IP Audio Transport
The Intraplex NetXpress IP audio multiplexer has built its reputation for
reliability at the heart of some of the world’s most complex and geographically
widespread IP audio networks. Today, Harris introduces the NetXpress LX™
multiplexer — delivering the same high-performance IP audio platform in a
scaled down, more affordable package.
Supporting both unicast and multicast, and compatible with the existing
NetXpress, the NetXpress LX system opens up new possibilities in IP audio
network design.
Existing T1/E1 Multiplexer Conversion to IP
CM-30 IP interface module; can convert existing T1/E1 systems to IP
Compatible with Intraplex NetXpress systems
Wide variety of audio, voice and data interface modules
Optional echo cancellation for 2-wire voice circuits
Transport of two contact closures in each direction
Adjustable packet size
Programmable jitter buffer depth
Advanced Intraplex forward error correction
Quality of Service (QoS) priority tagging
Unidirectional or bidirectional unicast streaming
Forget about retiring perfectly good Intraplex systems when moving from T1
or E1 to IP. The new NetXpress LX IP interface module, the CM-30, can replace
the network interface module in existing Intraplex T1/E1 systems, converting
them to IP while keeping the existing chassis with all of its audio, voice and
data cards.
Unidirectional multicast streaming
Intraplex Reliability
Event logging
When the mission is critical, broadcasters turn to Harris® Intraplex audio
transport systems — the standard-bearer for dependable, great-sounding
audio links for “always on” applications.
Built upon the technology of the original NetXpress system, but with a form
factor matching that of our T1/E1 systems, the NetXpress LX multiplexer
provides the reliable and robust performance demanded by studio-totransmitter link (STL) and other fixed, full-time inter-facility applications.
Available in two sizes — a 3RU frame with capacity for up to 17 application
modules and a compact 1RU frame that can hold five application modules —
the NetXpress LX system can also work as an “edge” device along with the
NetXpress multiplexer in large, multisite networks.

Network statistics monitoring
The NetXpress LX multiplexer provides the superior support and long-term
value expected from Intraplex — broadcasting’s first choice for rock-solid,
full-time operation of IP audio, T1/E1 and 950 MHz audio and data links.
