Terayon was a manufacturer of broadband networking equipment, best known for its TeraJet DOCSIS cable modems and digital video processing systems.
Terayon Communication Systems was a technology company specializing in broadband data and networking solutions. Founded in the 1990s, the company became well-known for its DOCSIS-compliant cable modems, such as the TeraJet ECM series, and its advanced digital video processing equipment, including the CherryPicker statistical multiplexer. These products were instrumental in the early expansion of high-speed cable internet and digital television services.
In 2007, Terayon was acquired by Motorola, and its technologies were subsequently integrated into Motorola's Connected Home Solutions business (later acquired by ARRIS and then CommScope). As a legacy brand, Terayon products are no longer actively manufactured or supported by the original entity.

Common questions about manuals, registration, and support for this brand.
Terayon was acquired by Motorola in 2007. Official support for Terayon-branded products is no longer available as the company is defunct. Some support may be found through third-party forums or ISP archives.
Most Terayon modems can be reset by unplugging the power adapter, waiting for 30 seconds, and plugging it back in. Some models may have a small reset button on the back panel that can be pressed with a paperclip.
Terayon modems are legacy devices typically supporting older DOCSIS 1.0, 1.1, or 2.0 standards. They are likely incompatible with modern high-speed cable plans that require DOCSIS 3.0 or 3.1 equipment.
USB drivers for Terayon modems were designed for older operating systems like Windows 98, 2000, and XP. They are generally not compatible with Windows 10 or 11. It is recommended to use the Ethernet connection instead of USB whenever possible.
