To improve the efficiency of bandwidth usage over the CCITT I.463 standard, for switching systems having a granularity of better than 64 Kbps (e.g. 8 Kbps), in a system for performing rate adaptation for synchronized sub-rate channels in a manner geared to package sub-rate data in fragment size envelopes for integer multiples thereof), the width of a fragment is matched (ideally equal) to the granularity of the system's switch. This improves the efficiency of the rate adaptation process and maximizes the use of the system's switching and bandwidth capacity. In a system having m slots of bandwidth per frame, n fragments per slot and a switch granularity of x Kbps, x is less than 64 and each fragment is x Kbps wide. |
