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： The present disclosure generally pertains to systems and methods for swapping span power modules that are used for supplying power to network interface units (NIUs). A span power module in accordance with one exemplary embodiment of the present disclosure has logic capable of communicating with logic of another span power module. When one module is to be swapped for the other module, the module being swapped-in is configured to automatically disable the other module shortly after it has powered up and is supplying electrical power across a span line. The amount of time that both modules supply power to the span line is sufficiently small such that damage to electrical communication equipment receiving power from the span line is prevented.

摘要： In a signal transmission network, such as a data network, having a multiple access bus topology (12) in which many nodes reside and communicate over the same bus, and wherein electrically isolated and/or physically different signal transmission media (17,18,19) are encompassed by the bus (12), and wherein a common protocol is used across the entire network; a multidirectional repeater (10) repeats signals from any one of the signal transmission media to one or more of the other signal transmission media, thereby providing a contiguous logical bus across the different signal transmission media. The multidirectional repeater (10) uses logic transitions, e.g., the presence or absence of data, a change in a data or logic state, the presence or absence of a carrier, a change in a carrier frequency, or any other suitable indication that data is present on one of the signal transmission media (17,18,19) for determining when to repeat signals from that signal transmission media to other signal transmission media and for determining when to stop repeating signals. An interface (21,22,23) is provided between each signal transmission media (17,18,19) and the multidirectional repeater (10) to disable the transmission of data to the bus (12) so that only signals from one signal transmission media are being repeated at a time. The multidirectional repeater (10) determines which data to repeat when data is available on one or more signal transmission media.
