ABSTRACT:
An NpR variable bandwidth control system comprises a class of systems specifically designed to control the access to a T1 link by traffic types that require different fractions of the transmission facilities simultaneoulsy. These systems can be incorporated into the software that is used to control DSC based T1 networks for special services. Essentially, wideband messages such as video signals are transmitted one at a time, whereas low bit rate data signals such as voice are transmitted in parallel. Such a form of transmission makes economical sense in the transmitting of such signals. A proportion p is applied to one of the group so that all data is equitably handled.
