Applications
The Toshiba DKS (Digital Key System) product line was a widely deployed business telephone platform used in small-to-medium businesses throughout the 1990s and early 2000s. The DKSUE424A served as the main system cabinet, housing the backplane, power supply, and interchangeable expansion cards that determined the system's line and extension capacity. PEKU1A cards provided digital extension ports for connecting Toshiba proprietary digital desk phones, while other cards handled central office trunk lines, voicemail integration, and system control functions. Replacement and spare cards for Toshiba DKS systems remain in demand for organizations still running legacy Toshiba PBX installations. This cabinet and its cards are suited for use as replacement parts, repair stock, or as a source of tested components for a working DKS system.
This Toshiba DKSUE424A Digital Business Telephone System (PBX) is being sold as-is for parts or repair. The system has not been tested and is not guaranteed functional. It includes two PEKU1A digital extension cards, RCTVBA3A, RCOV1A, RCOU1A, and RCTUBB3A expansion cards, and the RPSU280A power supply — all installed in the cabinet. The cabinet and cards appear physically intact with normal wear typical of removed office telecom equipment. Please view our photo set and contact us if you have any questions.
