This read-write object's only defined value is disabled(0), which disables the receive buffer and implies the clock mode is set to 'Rx satellite.' Unlike the CDM-570's richer buffer-size table, this CDD-564 object exposes essentially an on/off control tied to clock mode -- the buffer, when enabled, absorbs timing jitter between the satellite-derived clock and the terrestrial clock, so disabling it ties the unit's timing directly to the satellite-recovered clock rather than smoothing it. In a 'Rx satellite' clock-mode configuration where the terrestrial side is expected to simply follow the satellite-derived timing, an admin would leave this at disabled(0) rather than trying to configure an elastic buffer that isn't meaningful in that mode.
