TETHYS™ 4192 QUAD STS-192/STM-64 MUX/DEMUX GENERAL DESCRIPTION Tethys™ 4192 is optimized for SONET/SDH applica- tions as a full-duplex four STS-192/STM-64 MUX/ DEMUX with full framer functionality including pointer processing, and overhead termination; ideal for ag- gregation, ADM and DWDM applications. In the de- multiplex ingress direction, Tethys™ 4192 accepts four STS-192/STM-64 signals in SFI-4.2/SFI-4.1 for- mat. Tethys locates the incoming SONET/SDH frame, optionally de-scrambles the data, monitors the TOH and POH, and provides STS-1 level pointer pro- cessing. In addition, Tethys supports TOH and POH overhead transparency. In the multiplex direction, Tethys™ 4192 accepts four STS-192/STM-64 or sixteen STS-48/STM-16 sig- nals in either 4 x 2.5 Gbit/s or serial 2.5 Gbit/s format. Further Tethys provides corresponding functionality in the DEMUX direction.
