ABSTRACT:
An alignment logic together with an MFI extractor are adapted to compensate for differential delays. The MFI extractor extracts the MFI disposed in the path overhead of each constituent time-slot. The alignment logic uses the extracted MFI to align corresponding data words (i.e., data words that are transmitted during the same time period) at the receiving end of virtually concatenated channels and that occupy different time-slots of the same channel. To perform alignment, the alignment logic stores each data word in a RAM location that is defined by an associated MFI. The data words so stored are aligned when read sequentially from their stored locations. The synchronization logic in the alignment logic synchronizes all the constituent time-slots.
