CRU clock and data signals. (In this mode the VSC8113 operates just like the VSC8111). The receive section
also contains a SONET/SDH frame detector circuit which is used to provide frame pluses during the A1, A2
boundary in the serial to parallel converter. This only occurs when OOF is high. Both internal and external LOS
functions are supported.
