TETHYS™ 448 16 STS-48/STM-16 MUX/DEMUX GENERAL DESCRIPTION Tethys™ 448 is optimized for SONET/SDH applica- tions as a full-duplex sixteen STS-48/STM-16 or a mix of sixteen STS-12/STM-4 and STS-3/STM-1 MUX/DEMUX with full framer functionality including pointer processing, and overhead termination; ideal for aggregation, ADM and DWDM applications. In the demultiplex ingress direct ion, Tethys™ 448 accepts either sixteen STS-48/ STM-16, or a mix of sixteen STS-12/STM-4 and STS-3/ STM-1 signals in serial
2.5 Gbit/s or serial 622 Mbit/s or serial 155 Mbit/s for-
mat. Tethys™ 448 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™ 448 supports TOH and POH overhead transparency. In the multiplex direction, Tethys™ 448 accepts six- teen STS-48/STM-16 signals in serial 2.5 Gbit/s for- mat. Tethys™ 448 further provides corresponding functionality in the DEMUX direction.
