PEB1757E
TETHYS 2 STS-192/STM-64, 16 STS-48/STM-16, MUX/DEMUX
MARCH 2008
REV. 1.0.2
GENERAL DESCRIPTION
Tethys PEB1757E is optimized for SONET/SDH
applications as a full-duplex two STS-192/STM64 or
sixteen STS-48/STM-16 or a mix of sixteen STS-12/
STM-4 and STS-3/STM-1 MUX/DEMUX channel
device with full framer functionality including pointer
processing, and overhead termination; ideal for
aggregation, ADM and DWDM applications. In the
demultiplex ingress direction, Tethys PEB1757E
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
PEB1757E 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 PEB1757E supports
TOH and POH overhead transparency.
In the multiplex direction, Tethys PEB1757E
accepts sixteen STS-48/STM-16 signals in serial 2.5
Gbit/s format. Tethys PEB1757E further provides
corresponding functionality in the DEMUX direction.
