Time-of-Day Measurement (ToD-1pps)

The 7705 SAR can receive and extract time of day/phase recovery from a 1588 grand master clock or boundary clock and transmit the recovered time of day/phase signal to an external device such as a base station through an external time of day port, where available. Transmission is through the ToD or ToD/PPS Out port with a 1 pulse/s output signal. The port interface communicates the exact time of day by the rising edge of the 1 pulse/s signal.

The tod-1pps command specifies the format for the time of day (ToD) message that is transmitted out the ToD or ToD/PPS Out port and specifies whether the 1pps output is enabled.

CLI Syntax:

config>system>time
    tod-1pps
        message-type {ct | cm | irig-b002-b122 | irig-b003-b123 | irig-b006-b126 | irig-b007-b127} 
        output

Example:

config>system>time# tod-1pps
config>system>time>tod-1pps# message-type ct
config>system>time>tod-1pps# output
