Background

CableSoft was formed in 1987 to develop and market Cabledesigner, a small system/network design software package. The company reorganized in 1990 as Cablesoft Engineering, shifting its primary emphasis towards engineering and testing. CSEI was fully incorporated in 1993. Although Cabledesigner 2.1 is no longer actively maintained or marketed, it is still a valid design package for small HFC networks and system extensions and is available as a free download. The program allows for HFC RF/AC network design including customized equipment files and full BOM generation. A ZIP file containing all necessary executable files, help files, and users manual in MS Word format is available on the 'downloads' page.
