PEB2756AE:Tethys™ II 4x10G SONET/SDH Framer and Pointer Processor

Tethys™ II PEB2756AE is optimized for SONET/SDH applications as a full-duplex Quad (SFI4.2) or Dual (SFI4.1) 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™ II accepts four/two STS-192/STM-64 signals (SFI4.2/SFI-4.1 interfaces), locates the incoming SONET/SDH 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 direction, 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.
