Automatic Number Identification or ANI, is a scheme that uses selcall for identification purposes. Typically a mobile radio will be configured to transmit a preconfigured selcall sequence when the user presses the ‘ push-to-talk ’ (PTT) button, which will automatically identify them to other devices listening on the same frequency on the ...
In electric power systems and industrial automation, ANSI Device Numbers can be used to identify equipment and devices in a system such as relays, circuit breakers, or instruments. The device numbers are enumerated in ANSI / IEEE Standard C37.2 Standard for Electrical Power System Device Function Numbers, Acronyms, and Contact Designations .
Key Code Qualifier is an error-code returned by a SCSI device. When a SCSI target device returns a check condition in response to a command , the initiator usually then issues a SCSI Request Sense command .
The detection of a RESET signal causes the processor to enter a system initialization period of six clock cycles, after which it sets the interrupt request disable flag in the status register and loads the program counter with the values stored at the processor initialization vector ($00FFFC – $00FFFD) before commencing execution.
