Technology Transfer for OEMs

Each MIDAS product is a Technology Transfer Package that gives you full control over your product design and direction. You can customize, add value or change form factor. You have full flexibility for your first and future products because MIDAS Gold Level Products include a complete Hardware Design Kit, Software Source Code Kit, and Object Code. You get fully functioning boards loaded with Object Code; schematics, Gerber files, board layout and component listings.

The MIDAS-UEN is one member of a growing family of MIDAS (Modular ISDN Data Access Solution) products that are designed specifically to meet the needs of OEMs and ODMs for fast development of low cost ISDN products. Other BRI and PRI MIDAS products are available for North America, Europe, Australia and Korea. Implementations include internal active and passive cards and external boxes.

*TeleSoft has established Gold and Silver Levels of fit and finish for its MIDAS Products. In achieving the Gold Level, the product has met applicable Telco Conformance Standards, passed interoperability tests with industry-leading devices and is ready for Beta test production.
