Subject: what might FTQ be in telecommunication ? FTQ - ????time quality ???
контекст: Команда FTQ Command (Access Level 2)
The FTQ command forces a selected value for the IEEE 1344 and IEEE C37.118 extensions time-quality output (useful for testing whether IEDs connected to the clock outputs are properly receiving and decoding these extended control function bits). To force a time-quality output, issue the command FTQ n, where n represents a time-quality value shown in Table 12. The ENABLED LED changes to yellow, and the remaining indicator LEDs show clock status based upon the selected time-quality value. To return to normal operation, issue the FTQ C (clear) command. The SEL 2407 forces and reports the time-quality values listed in Table 12 during this testing mode. To display the time quality, see DTQ Command (Access Level 2). Only use the FTQ command when the clock is in Satellite Lock or manual time mode.
