Applications

The Comdial Executech series was a line of digital key telephone systems aimed at small businesses that needed multi-line call handling without the complexity or cost of a full enterprise PBX. The 0816X controller serves as the central processing unit of the Executech system, connecting incoming PSTN lines and distributing calls to Executech-compatible digital keysets throughout an office. The system supports features common to 1990s-era business telephony such as hold, transfer, intercom, and music-on-hold via the dedicated music connection input. The two 50-pin expansion connectors on the bottom panel allow station cards or expansion modules to be added for additional telephone sets. Comdial Executech systems were widely deployed in professional offices, retail environments, and small call centers during the 1990s, and replacement or spare controllers are still sought by businesses and technicians maintaining legacy Comdial installations.
