GENERAL DESCRIPTION
Tethys™ 4192 is optimized for SONET/SDH applications as a full-duplex four STS-192/STM-64 MUX/DEMUX with full framer functionality including pointer processing, and overhead termination; ideal for aggregation, ADM and DWDM applications. In the demultiplex ingress direction, Tethys™ 4192 accepts four STS-192/STM-64 signals in SFI-4.2/SFI-4.1 format. Tethys locates the incoming SONET/SDH frame, optionally de-scrambles the data, monitors the TOH and POH, and provides STS-1 level pointer processing. In addition, Tethys supports TOH and POH overhead transparency.
