Has_AU3
The following table lists all valid contiguous concatenation settings:
Each AUG-1 time slot that is not part of a contiguous concatenated container, can
independently be configured to consist of a single VC-4/STS-3c SPE or three VC-3/STS-1’s
SPE. A Has_AU3 register per AUG-1 time slot determines the structure of that time slot.
In STM-1/OC-3 mode each line interface transports a single AUG-1. With the Has_AU3
register each AUG-1 can independently be configured to consist of a single VC-4/STS-3c
SPE or three VC-3/STS-1’s SPE. In STM-1/OC-3 mode, it is mandatory that the
TimeSlotIsConcatenated registers are set to the default master mode.
Another set of configuration registers is available for the Add and Drop Combus interfaces
when the AUG-1 contains AU-4’s. Four bits, Is_TUG_Structured, specify whether the
corresponding VC-4 contains TUG-3’s or C-4. This register is only applicable for the Combus
configuration and is a don’t care when the corresponding AUG-1 is part of a non-standard
concatenated structure or when the AUG-1 contains three AU-3’s.
When TUG-3 is mapped in VC-4/AU-4 or VC-3 is mapped in AU-3 an extra register is
provided to specify whether these containers contain TUG-2 or not. These configuration bits
are don’t care for the VC-4’s containing C-4.
