One to Four Channels
Up to four independent, non-compressed,
full-duplex T1 channels are provided (depending on model). This capability provides an
alternative to leased lines or traditional licensed radio for fast and easy connection of
T1 capacity requirements.Spread spectrum
technology allows a license-free approach to accomplish medium-capacity spur connections
quickly, without FCC 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,
loop-back 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 50 miles, line-of-site.
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 five models
for full-duplex T1 (1.544 Mbps) wireless communications: 2.4 GHz T1, 5.8 GHz T1, 2.4 GHz 2
x T1, 5.8 GHz 2 x T1 and 5.8 GHz 4 x T1. The LYNX.sc family also offers a similar line of
E1 (2.048 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. |

| OpenLYNX™ Network Management System |
|
|
OpenLYNX™ implements an open
protocol for management of LYNX.sc radio networks using three elements:
- Embedded TBOS agent
- Windows 95™ graphical user interface (GUI)
- Wayside 9600 baud data channel with RS-232 ports
TBOS (Telemetry Byte Oriented Serial) is an open
standard for network management, originally developed by Bellcore for AT&T. The TBOS
protocol is a simple and reliable serial polling design. A TBOS agent embedded in every
LYNX.sc responds to any standard TBOS network manager.
The (optional) GUI is a Windows 95™-based
software package that includes a TBOS network manager. This program interprets the TBOS
information provided from a network of LYNX.sc radios and provides top-level status
(red/green/yellow), virtual front panels, alarm and status logs and remote controls of the
connected LYNX.sc radios. |

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 mile to more than 50 miles. The installation shown provides a rural telephone T1
extension using a 5.8 GHz 2 foot 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. |
|
|
|
|
|
|
|
The LYNX.sc is the
third generation of the LYNX family. Introduced by Western Multiplex Corporation in 1992,
the LYNX was the first T1/E1 spread spectrum radio in the world. LYNX, the world leader of
T1/E1 spread spectrum, has earned a reputation for ease of use and excellent reliability. |
