In the demultiplex ingress direction, Tethys™ 4192 accepts two STS-192/STM-64 signals in SFI-4.1 format. Tethys locates the incomi ng SONET/SDH frame, optionally descrambles the data, monitors theTOH and POH, and provides STS-1 level pointer processing. In addition, Tethys supports TOH and POH overhead transparency. In the multiplex di rection, from the system interface, Tethys™ 4192 accepts two STS-192/STM-64 or eight STS-48/STM-16 signals in ei ther dual 4 x 2.5 Gbit/s or 8 serial 2.5 Gbit/s format. Further Tethys provides corresponding functionality in the DEMUX direction.
