REV. 1.0.0
GENERAL DESCRIPTION
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.
