Abstract
For use in a communications network capable of establishing a bonded call between first and second endpoints using at least two bonded communication channels, a subsystem for preserving a relative latency of the at least two bonded communication channels to allow the bonded call to be transferred to a third endpoint. The subsystem includes: (1) a buffer depth index detection circuit that detects learned values of buffer depth indices associated with the bonded call and stored at a first location and (2) a buffer depth index transmission circuit, coupled to the buffer depth index detection circuit, that transmits the learned values to a second location accessible by the third endpoint to allow the bonded call to be transferred to the third endpoint without requiring the third endpoint to relearn the values.
