To physically wire components together to form a system or subsystem rather than using switches, plugs, or connectors. Early electromechanical key telephone systems (KTSs), for example, were hardwired and, therefore, both limited in feature content and highly inflexible. In contrast, contemporary electronic common control (ECC) systems are microprocessor-based, software-controlled, and, therefore, easily upgradeable and highly flexible. See also ECC, KTS, and software.
To build a function into a system with hardware, rather than software. Hardwired logic is fixed, i.e., inflexible, and cannot be reprogrammed. See also hardware and software.
