This read-write object sets the Rx buffer size across a much richer set of options than the CDD-564's simple on/off control, from disabled(0) through several sizes ranging from +/-128 bits up to +/-32786 bits, as enumerated in the object's syntax. This buffer absorbs the slow clock drift between the recovered satellite timing and the terrestrial equipment's clock, and choosing its size is a tradeoff between added latency, since a larger buffer adds more delay to every bit passing through it, and resilience to clock drift or Doppler-induced timing variation, since a larger buffer tolerates more drift before slipping. On a link experiencing noticeable Doppler-related clock drift, an admin who observes periodic buffer-slip alarms with a small buffer size might increase it to a much larger size to accommodate the drift rate without slipping, accepting the added latency as a worthwhile tradeoff.
