摘要： A timing architecture for integrating broadband, wideband, and narrowband subsystems (14-18) employs a broadband time base (100) having a first frequency, a wideband time base (102) having a second frequency, and a narrowband time base (104) having a third frequency. The broadband, wideband and narrowband time bases (100-104) are independent from one another when the integrated subsystems (14-18) are not co-located. Frequency justification is provided at the interfaces between the broadband and wideband time bases (100, 102), and between the wideband and narrowband time bases (102, 104). Phase alignment circuitry and methods are used to adjust the phases of signals wherever signal multiplexing and redundant equipment switching are provided within the time bases (100-104).

摘要： An integrated multi-rate cross-connect system (10) includes a broadband subsystem (14) for processing optical and electrical telecommunication network signals. A wideband subsystem (16) processes wideband level electrical telecommunication signals from the network, from the broadband subsystem (14), and from a narrowband subsystem (18). The narrowband subsystem (18) processes narrowband level electrical telecommunication signals from the network and the wideband subsystem (16). An administration subsystem (12) provides centralized control and synchronization to the broadband subsystem (14), the wideband subsystem (16), and the narrowband subsystem (18). The wideband subsystem (16) is coupled to the broadband subsystem (14) and the narrowband subsystem (18) by internal transmission links (30) 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.

摘要： A grooming device (18) includes an inbound crosspoint switch (30) that combines proprietary STS-1 signals from any of a plurality of optical terminators (16) into a grouped set of output signals for transmission to a broadband matrix subsystem through dedicated matrix interfaces (20). The inbound crosspoint switch (30) includes a crosspoint matrix (72) that receives each of the plurality of input signal lines at each output signal port and selects which input signal line is connected to which output signal port as determined by a microprocessor controller (78). Each output signal port has a register (90) for storing information as to which input signal line is to be connected to that port. A decoder (92) generates a control signal from the information stored in the register (90) to drive a multiplexer (94) for selection of the appropriate input signal line.

摘要： In the inbound direction, a tributary processor (32) includes an SPE encoder/decoder for extracting a synchronous payload envelope (SPE) from an STS-1P signal. A path terminator (62) may extract DS3 signals or a matrix payload envelope (MPE) from the STS-1P SPE. A DS1/DS3 extractor (68) generates DS1 signals from either the DS3 or MPE signals. An MPE mapper (70) creates MPE signals from the DS1 signals. A wideband stage interface (74) converts the MPE signals into matrix transport format (MTF) signals for cross-connection in a wideband center stage matrix (22). In the outbound direction, the wideband stage interface (74) receives MTF signals from the wideband center stage matrix (22) and generates MPE signals therefrom. The MPE signals are sent through the MPE mapper (70) in order to extract DS1 signals. The DS1 signals are converted to DS3 signals or another MPE mapping by the DS1/DS3 extractor (68). 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.
