Virtual Concatenation

Virtual concatenation (VCAT) is an inverse multiplexing technique creating a large capacity payload container distributed over multiple smaller capacity TDM signals. These signals may be transported or routed independently. Virtual concatenation has been defined for SONET/SDH, OTN and PDH path signals.

Alternate SONET/SDH concatenation techniques are contiguous concatenation and arbitrary concatenation.

Famous quotes containing the word virtual:

    Neither dead nor alive, the hostage is suspended by an incalculable outcome. It is not his destiny that awaits for him, nor his own death, but anonymous chance, which can only seem to him something absolutely arbitrary.... He is in a state of radical emergency, of virtual extermination.
    Jean Baudrillard (b. 1929)
