370512, 370466, 370360

A timing architecture for a delivery unit that interfaces telecommunications media to a switching matrix. The delivery unit is functionally partitioned into a number of application modules. Transport between the modules is handled by a bus control module, with ingress buses from the application modules to the bus control module and egress buses from the bus control module to the application module. The bus control module also distributes system timing signals to each application module on these buses. The application modules each have a common bus interface that derives common local timing signals. They also each have a common local timebase that derives additional local timing signals. The bus interface is also used to deliver synchronization signals back to the bus control module.

An apparatus and system are provided for delivering communication services such as video, data and telephony services to individual residential units. According to one embodiment, an optical network terminal (ONT) for providing communication services to a single residential unit comprises a passive optical network interface (PI) circuit, a residential service interface (RSI) circuit, and a power unit. The PI circuit receives optical signals from an optical fiber and transmits optical signals onto the optical fiber. The PI circuit is adapted to convert received optical signals containing voice information to electrical voice ATM cells, received optical signals containing data information to electrical data ATM cells, and received optical signals containing video signals to electrical video signals. The PI circuit is also adapted to convert electrical voice ATM cells and electrical data ATM cells to optical signals for transmission over the optical fiber;The RSI circuit that is adapted to convert the electrical voice ATM cells to a telephony format suitable for use at the residential unit and the electrical data ATM cells to a network format suitable for use at the residential unit. The RSI circuit is also adapted to convert telephony format information received from the residential unit to voice ATM cells and network format information received from the residential unit to data ATM cells.

A system for interfacing with a data bus is provided. The system includes an egress bus data interface that can receive a single incoming stream of STM data and ATM data. The egress bus data interface transmits a single incoming stream of STM data, and a single incoming stream of ATM. The system also includes an ingress bus data interface. The ingress bus interface receives a single outgoing stream of STM data and a single outgoing stream of ATM data. The STM data and ATM data are transmitted in a single outgoing stream.

A system for selecting one of two or more parallel planes of data is provided. The system includes a first data buffer that is connected to a first data bus that carries a stream of datagrams. The first data buffer receives and stores datagrams from the first data bus. The system also includes a second data buffer that is connected to a second data bus that carries a stream of datagrams. The second data buffer receives and stores datagrams from the second data bus. A selection controller connected to the first data buffer and the second data buffer analyzes the datagrams stored in the first and second data buffers, and selects one of the datagrams to be the primary datagram.

A data bus controller is provided. The data bus controller comprises an ingress interface that receives single data streams of encoded data. A multiplexer is connected to the ingress interface and combines the single data streams into a broadcast data stream of encoded data. An egress interface connected to the multiplexer transmits the broadcast data stream. An arbiter is connected to the multiplexer. The arbiter generates control data for controlling the multiplexing of the single data streams and transmits control data to the multiplexer.
