Method and apparatus for translating differently-sized virtual tributaries organized according to a synchronous optical network (SONET) standard

摘要

A SONET virtual tributary reformatter has a drop encoder that receives incoming data of a second VT size mapped according to first VT size and provides the data in a format designed for the first VT size and also has an add decoder that receives outgoing data signals of the second VT size in the format of the first VT size and provides the outgoing data of the second VT size mapped according to the first VT size.
