method for the creation of a network of connection for signals belonging to the hierarchy sdh (synchronous digital hierarchy synchronous), and integrated circuits for the implementation of the method

摘要

the invention relates to a method and circuit semicustom for the creation of a network of connection for signals belonging to the hierarchy sdh (synchronous digital hierarchy synchronous)with special characteristics of system flexibility and proteggibilitu00e0 to breakups.commutabili signals are all dependent synchronous lower order in the etsi standard, that is to say, vc12, vc2, and vc3 (virtual container of level 12.2 and 3) and therefore the found is a possible implementation of the function the lpds (lower path connection) for the standard ccitt g783 for multiplatori compatible with the standard sdh.the found is a network of connection as a set of matrices to 2 stages.the first frame and the second space; the plot at the entrance of the stadium in time is modified with respect to that described by the standard to ensure the equalization of delay inintroduced on the stage storm tax interconnected system.
