International Classification:

H04L012/50

US Classification:

370/359000, 370/474000, 370/503000, 370/535000

Abstract:

In the inbound direction, a tributary processor () includes an SPE encoder/decoder for extracting a synchronous payload envelope (SPE) from an STS-1P signal. A path terminator () may extract DS3 signals or a matrix payload envelope (MPE) from the STS-1P SPE. A DS1/DS3 extractor () generates DS1 signals from either the DS3 or MPE signals. An MPE mapper () creates MPE signals from the DS1 signals. A wideband stage interface () converts the MPE signals into matrix transport format (MTF) signals for cross-connection in a wideband center stage matrix (). In the outbound direction, the wideband stage interface () receives MTF signals from the wideband center stage matrix () and generates MPE signals therefrom. The MPE signals are sent through the MPE mapper () in order to extract DS1 signals. The DS1 signals are converted to DS3 signals or another MPE mapping by the DS1/DS3 extractor (). The path terminator receives DS3 or MPE signals for conversion into an STS-1P SPE. The SPE encoder/decoder creates the STS-1P signals from the STS-1P SPE for transmission to the appropriate interfaced subsystem or network.

US Classification:

370/395100, 370/401000

Abstract:

An integrated multi-rate cross-connect system () includes a broadband subsystem () for processing optical and electrical telecommunication network signals. A wideband subsystem () processes wideband level electrical telecommunication signals from the network, from the broadband subsystem (), and from a narrowband subsystem (). The narrowband subsystem () processes narrowband level electrical telecommunication signals from the network and the wideband subsystem (). An administration subsystem () provides centralized control and synchronization to the broadband subsystem (), the wideband subsystem (), and the narrowband subsystem (). The wideband subsystem () is coupled to the broadband subsystem () and the narrowband subsystem () by internal transmission links () to allow for remote distribution of each subsystem. Each subsystem operates within its own timing island synchronized to a reference timing signal to facilitate component distribution.

International Classification:

G02B 6/36

US Classification:

385 76

Abstract:

A wall-mountable outlet comprising an enclosure and a faceplate mechanically coupled to the enclosure. An optical network terminal (ONT) is provided in the enclosure. In one example embodiment, the ONT comprises an optical-electrical (O-E) data module, and the O-E data module comprises an O-E converter. The O-E data module can further comprise a switch arranged to selectively couple at least one signal with the O-E converter. The O-E data module further can comprise a Passive Optical Network (PON) controller interposed between the O-E converter and the switch.

Abstract:

An integrated multiple cross-connect system (10) having remotely located components interconnected by integrated office links is provided. The system (10) includes a broadband matrix (20), at least one remotely located high speed line terminating equipment (30, 32) coupled to a telecommunications network, and an integrated office link (34, 36) interconnecting the broadband matrix (10) and high speed line terminating equipment (30, 32), the integrated office link (34, 36) carrying duplex transmission of an IOL-N signal of N multiplexed STS-1P optical signals at an OC-N rate, the STS-1P signal including data payload and overhead fields. Further included is a remotely located wideband matrix (22), a second integrated office link (40) interconnecting the broadband matrix (20) and the remotely located wideband matrix (22), and at least one remotely located low speed line terminating equipment (54) coupled to a telecommunications network, where the wideband matrix (22) and low speed line terminating equipment (54) are interconnected by a third integrated office link (59). Fault coverage information including a cross-connect channel identification code and a parity value are among the IOL overhead fields. The fault coverage information in the IOL overhead fields are monitored at selected points along a transmission path.
