PEB2757AE:Tethys™ II 4x10G, 16x2.5G/622M/155M SONET/SDH Framer and Pointer Processor

Tethys™ II PEB2757AE is optimized for SONET/SDH applications as a full-duplex four channel (SFI4.2) or two channel (SFI4.1) STS-192/STM64 or mix of sixteen MUX/DEMUX channels of STS-48/STM-16 or STS-12/STM-4 or STS-3/STM-1 (in groups of four channels). The device has full framer functionality including pointer processing, and overhead termination; ideal for aggregation, ADM and DWDM applications. In the demultiplex ingress direction, Tethys™ II PEB2757AE accepts either two STS-192/STM-64 or 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 format. Tethys™ II PEB2757AE locates the incoming SONET/SDH frame, optionally de-scrambles the data, monitors the TOH and POH, and provides STS-1 level pointer processing. In addition, Tethys™ II PEB2757AE supports TOH and POH overhead transparency.

In the multiplex direction, Tethys™ II PEB2757AE accepts sixteen STS-48/STM-16 signals in serial 2.5 Gbit/s format. Tethys™ II PEB2757AE further provides corresponding functionality in the DEMUX direction.
