In the demultiplex ingress direction, Tethys™ II accepts four/two STS-192/ STM-64 signals (SFI4.2/SFI-4.1 interfaces), locates the incoming SONET/SD H frame, optionally descrambles the data, monitors the TOH and POH, and provides STS-1 level pointer processing. In addition, Tethys supports TOH and POH overhead transparency. In the multiplex directio n, Tethys™ II PEB2756AE accepts sixteen STS-48/STM-16 signals in serial 2.5 Gbit/s format. Tethys™ II PEB2756AE further provides corresponding functionality in the DEMUX direction.
