摘要： 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.

摘要： A method for processing cells at a user-network interface with automatic identification of virtual circuit identifiers and a testing function is provided. The method includes distinguishing the source of the cell. When the cell is from a first source, the method tests the cell against at least one selected criteria. When at least one test determines the cell is invalid, the cell is marked. When the tests determine that the cell is valid, the method translates a virtual circuit identifier to a default setting and forwards the cell to a queue for further processing.

摘要： A distributed telecommunications switching subsystem (100) receives and distributes data packets passed between a plurality of switching subsystems or channel banks (102, 104, 106) and a data packet switch (110). Each channel bank (102) has a stored list of addresses. When a channel bank (102) receives a data packet, it compares the address of the data packet to its stored list of addresses, and transmits the data packet to another channel bank (104) if the address of the data packet does not correspond to any of the addresses in its stored list of addresses. The data packet is passed on until it reaches a channel bank (106) with a matching address or else it is appropriately handled by a last channel bank (106) in the chain. If the address of data packet matches an address in its stored list of addresses, the channel bank (102) passes the data packet through a subscriber interface card (120) to a customer premises equipment unit (108) corresponding to the address of the data packet.
