Open network management One to Eight Channels
Up to eight independent, non-compressed, full-duplex E1 channels are provided (depending on model). This capability provides an alternative to leased lines or traditional licensed radio for fast and easy connection of E1 capacity requirements.
Spread spectrum technology allows a license-free approach to accomplish medium-capacity spur connections quickly, often without regulatory licensing or coordination.
Full-Featured
Built-in orderwire provides an easy means for private telephone connections between radio sites. Open network management yields flexibility for operators with central equipment monitoring facilities. The one-piece indoor design, loopback functions, flexible power connections and external adjustments result in a system that is easy to install and maintain. Also, wide temperature operation allows users to install LYNX.sc in outdoor cabinets or shelters without additional air conditioning or heating.
Applications
LYNX.sc digital microwave radios are easily connected to voice, data or video sources. Outstanding system gain provides wireless point-to-point link distances greater than 80 km, line-of-sight. Hub and repeater configurations are also easily implemented.
Typical applications include cellular/PCS base station interconnect, rural telephone and remote data connections.
The LYNX.sc Product Line
The LYNX.sc family offers six models for full-duplex E1 (2.048 Mbps) wireless communications: 2.4 GHz E1, 5.8 GHz E1, 2.4 GHz 2 x E1, 5.8 GHz 2 x E1, 5.8 GHz 4 x E1 and 5.8 GHz 8 x E1. The LYNX.sc family also offers a similar line of T1 (1.544 Mbps) and fractional capacity (56 to 512 kbps) radios. Each model offers selectable frequency channel plans with excellent adjacent channel performance, resulting in easy installation of repeaters and hubs. In addition, the LYNX.sc provides a combination of several exclusive features, yielding increased flexibility and reliability as well as lower cost installation and maintenance.
Wide Operational Temperature Range
Windows 95™ GUI Easy to Install: Small dish or flat panel antennas can be used at both 2.4 and 5.8 GHz, along with low-loss coaxial cable to provide excellent performance for line-of-sight distances from less than 1 km to more than 80 km. The installation shown provides a rural telephone E1 extension using a 5.8 GHz 60 cm parabolic dish and 1 /2 inch coaxial cable, mounted on a telephone pole.
Hub Site Engineering: Using standard microwave radio path engineering practices, LYNX.sc radios can be integrated into hub sites, even in the presence of other spread spectrum and licensed microwave systems. This site illustrates seven LYNX.sc radios, all operating in the 5.8 GHz band, located at a hub site that also employs a variety of licensed microwave radios.
Cabinet Mounting: The LYNX.sc can be mounted in existing equipment cabinets, stand-alone cabinets or any weatherproof enclosure. Occupying only two rack mount units (with no outdoor mounted electronics) plus a -30 to +65 degree Celsius operating temperature range, the reliable LYNX.sc is very easy to install and maintain. The LYNX.sc is shown mounted in a telephone switch cabinet without air conditioning or heating.
Network Management: Utilizing an open architecture protocol, the LYNX.sc can be integrated into existing network management systems. OpenLYNX™ gives users a fast and intuitive system for control, diagnostics and troubleshooting of the radio network.
