摘要： A switch module for time switching telecommunications data includes an input circuit for selecting data samples from a time slot in an input frame of data samples. The selected data samples are arranged into groups of uniform size, each group consisting of at least two data samples. The groups of selected data samples are stored in an orderly manner, in each of as many storage entities as there are data samples in each group. Thereafter in accordance with a predefined sequence peculiar to each of the storage entities, the data samples are simultaneously read out, group by group. An output circuit selects data samples into a selected group of data samples from among each of the readouts of each of the storage entities and transmits each selected group into an output frame of data samples. Hence a sequence of the data samples appears switched in the output frame with respect to the sequence of the data samples as they were stored from the input frame. The switch module as described inherently provides for switching of data samples, the data samples being permitted to occur at a rate faster than a cycle time of switch module operation.

摘要： The present invention guarantees that voice data (and other information types) will switch within a predetermined time period. Systems and methods consistent with the present invention accomplish this guarantee by, among other things, establishing permanent virtual paths between each network element, guaranteeing each voice line a slot in a packet in each frame, employing both octet switching and packet switching, synchronizing the operation of the network elements to a reference clock, and providing several levels of network redundancy.
