PEB2756AE
TETHYS™ II QUAD STS-192/STM-64 MUX/DEMUX
OCT 2009
REV. 1.0.0
GENERAL DESCRIPTION
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.
APPLICATIONS
