A single device provides 40Gb/s of non-blocking STS-1 connectivity (768x768 STS-1) with support for concatenated tributaries. All STS-12/STM-4 inputs and outputs are differential serial signals running at 622 Mb/s for efficiency in switch card and system backplane design. Backplane BER monitoring and deskew are integrated, and the connection matrix can be hitlessly reconfigured. Path AIS or UNEQ can be optionally inserted into all 768 outgoing STS-1 tributaries. A standard asynchronous CPU interface with event interrupts is also supported.

Multiple VSC9182 devices can be used in a three layer Clos architecture to construct larger switches, up to 1024 OC-48 ports. The VSC9182 is designed to interface directly with the VSC9186 10Gb/s Pointer Processor & Frame Aligner and VSC9180 2.5Gb/s Backplane Transceiver.
