Abstract

Methods for bit-level control of dynamic bandwidth allocation are adapted for use in multi-node channelized transport systems. A single status bit is used to indicate the desired allocation status of each transport channel for which dynamic allocation is permitted or desired. The status bit has a first logic level indicative of a desire to have a first allocation status, such as allocated for data traffic, and a second logic level indicative of a desire to have a second allocation status, such as allocated for voice traffic. The status bit may be repeated multiple times within a frame to mitigate the effects of transmission errors. The values of the status bit or bits can be maintained across node boundaries without regard to the framing mechanisms or multiplexing techniques used by the transport system, thus permitting dynamic bandwidth allocation beyond the local loop.
