The present invention relates to an interface and method for enabling interconnection of a host device and a small-formfactor pluggable module. The interface comprises a host device connector operative to receive a mating small-formfactor pluggable module connector and a switching device connected to the host device connector and operative to selectively switch at least one signal carried over the host device connector between at least two separate signal paths of the host device depending on a selected switching mode of the switching device.

A manner of managing data transmission and operating-mode transitions in a communication network. A network node having a transmitter and receiver is selectively transitioned into a Transmit state, where the Transmit state is a condition wherein the transmitter is turned on for data transmission only during timeslots provided for by a PBW (pre-allocation bandwidth) and remains off otherwise. The PBW and clock drift allowance permits the receiver to remain off during all or most of the Transmit state.

A transmitting device is provided which includes a plurality of input interfaces, each of which receives a signal from another device, a plurality of output interfaces, each of which transmits a signal to another device, a multiplexing unit which multiplexes the signals received by the plurality of input interfaces, a distributing unit which transmits the signal multiplexed by the multiplexing unit to each of the plurality of output interfaces, and a table storage unit which stores a switching table in which a transmission destination of each signal is defined. The output interface extracts a signal which the output interface is to transmit according to content of the switching table from each signal included in the signal multiplexed by the multiplexing unit, and transmits the extracted signal to a transfer destination according to the content of the switching table.

The subject matter described herein includes methods, systems and computer readable media for automatic, peer node transparent re-homing of time division multiplexed (TDM)-based signaling channels in an X user adaptation (XUA) signaling gateway. One exemplary method includes providing an XUA Signaling Gateway (SG) having a plurality of Signaling Gateway (SG) cards, a plurality of TDM network interface cards (NICs) and a plurality of packet NICs, and a switching matrix connecting the TDM NICs and the XUA SG cards. The method further includes configuring the switching matrix so that a first XUA SG card terminates a set of TDM-based signaling channels. The method further includes switching the set of TDM-based signaling channels from one of the TDM NICs to the first XUA SG card. The method further includes switching the set of TOM-based signaling channels, detecting failure of the first XUA SG card, and automatically reconfiguring the TDM switching matrix so that the set of TDM-based signaling channels is sent to a second XUA SG card of the plurality of XUA SG cards.

A packet forwarding unit such as a Digital Subscriber Line Access Multiplexer (DSLAM) receives Ethernet packets carrying real-time information and forwards the information therein on output lines such as Asymmetric Digital Subscriber Lines (ADSLs). The DSLAM includes a clock device having an extraction unit and an adaptive clock. The extraction unit analyzes received packets to select streams of received packets from one destination to one user, and the adaptive clock generates a reference clock signal according to the arrival times of packets in the selected streams. The clock signal is sent to time reference units in DSL modems for the output lines.

A data and voice communication system includes communication between a line card and an accelerator card. Voice, data, and control traffic is received from the line card and is transmitted to the accelerator card via a physical link having separate voice, data, and control logical channels. The separate voice, data, and control logical channels are represented by labeled data packets.

A call routing device in a communication network is re-entrant to permit a set of call routing rules to be applied more than once. A routing table in the routing device has entries to indicate that an incoming call should be rerouted to the routing device to permit additional call routing rule(s) to be applied to the incoming call. A routing table is provided with entries to indicate when an incoming call should be rerouted to the routing device and how call attributes should be created/modified to achieve call routing in one or more iterations of call routing processing using the routing table. The re-entrant routing device and routing table permits a wide variety of call attributes to be used to direct call routing processing using a routing table that can have a reduced number of entries. The re-entrant routing device and routing table permits a flexible configuration for call routing in communication networks while conserving routing device resources.

A new architecture capable of utilizing the existing twisted pair interface between customer premises equipment and an associated serving local switching office is used to provide a vast array of new services to customers. Using an intelligent services director (ISD) at the customer services equipment as an interface for the equipment to an existing twisted cable pair and a facilities management platform (FMP) at the serving local switching office as an interface to various networks and service opportunities, new services such as simultaneous, multiple calls (voice analog or digital), facsimile, Internet traffic and other data can be transmitted and received over the twisted cable pair by using digital subscriber loop transmission schemes. The new services include but are not limited to videophone, utility meter reading and monitoring, broadcasting and multicasting. The architecture provides for fault-tolerant, transparent interaction of components and services and supports a variety of standards for each level of the open systems interconnection layers and layers of TCP/IP. The FMP connects electronically or optically to the public switched telephone network, Internet backbone, a private Intranet as well as other possible network connections.
