Company Overview
NATURE OF BUSINESS Linear Systems Ltd., is a developer and manufacturer of OEM communications products. Linear specializes in developing high speed WAN cards and software for use in data communications for satellite modern, T1, multiple T1, Fractional T3, DVB. Our products are used for general data communications and MPEG video transmission. Linear also produces an MPEG Transmission system and a Video conferencing system which use it's communications cards and software.
COMPANY BACKGROUND AND HISTORY Linear Systems Ltd., is a privately owned Canadian company which was formed in 1979 to provide computer and instrumentation support for the Potash Industry. Linear designed and installed custom computer control systems for monitoring concentration and transporting and storing potash.
Linear began to manufacture computer boards for Multibus computers, which were needed for potash applications, including real time calendar clocks, non-volatile memory, I/O boards, and serial communications cards. Linear began to market these boards to OEMs in 1981. In 1983 Linear began to market it's products in the USA through Computer Modules, Inc., a company located in California. Communications cards became a main product by 1990. Linear's boards were used in many applications including satellite receiving stations, the receiving station for the Galelao Probe, and early market testing for Video on Demand. In 1996, Linear Systems was registered to conform with the ISO 9001: 1994 quality system. As a result of this early experience with MPEG video, linear began to market computer boards and software specifically for this niche.
More recently, Linear has developed systems based on it's communications hardware and software. This includes the MPEG Shuttle, which is an MPEG transmission system for sending video over satellite or T1/E1 lines and a point to point Video conferencing system based on MPEG 1 which uses a single T1 line. Linear is currently expanding it's line of boards to support the DVB protocol and is extending it's line of WAN cards to support T3 and Sonet speeds.

TECHNOLOGY PROFILE Linear Systems Ltd. develops board level products for PCI and ISA bus computers. These boards are designed using surface mount, multi-layer technology and are designed for high volume manufacturing processes. Linear assemblies and tests it's cards at it's plant in Winnipeg.
Linear has developed WAN Network cards with standard daughter card (IM Module) interfaces which include EIA-530, RS-422, V.3, X.21, RS-449, RS-422 and HSSI. Linear has also developed a T1 interface IM Module. The WAN cards can accept two IM Modules which gives two channels per card. Data rates up to 13.3M bits/second are possible, DVB cards are also available for general data transport and for MPEG compressed video applications.
Linear has developed a comprehensive range of Windows NT 4 and Windows 95/98 drivers for the WAN cards, NDIS drivers provide standard interfaces for general purpose network applications. Specialized Kernel drivers for Win NT provide interfaces for HDLC framed data transport, or for MPEG Stream transport. Equivalent Win 95/98 VXDs have also been developed.
Linear has developed technology for transporting MPEG over satellite or T1 lines. This technology includes:
- Use of TCP/IP or UDP for MPEG or data transport in Network
applications
- Use of HDLC framing for MPEG transport from point to point
- Transmission of raw MPEG streams with no framing, half duplex
mode
- DVB transport of MPEG point to point half duplex.
Linear has developed new products based on it's MPEG networking technology.
- MPEG Conf: a full duplex MPEG Video conferencing over a single
T1 line
- MPEG Shuttle: a point to point MPEG transport system for
transmitting live video or video files from point to point.
- T1 Multiplexer: a system for transmitting a DVB MPEG stream
over multiple T1 lines, then converting back to DVB.
