Tethys鈩?4192 is optimized for SONET/SDH applica-
tions as a full-duplex four 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鈩?4192 accepts
four STS-192/STM-64 signals in SFI-4.2/SFI-4.1 format.
Tethys 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 supports TOH and POH overhead
transparency.
In the multiplex direction, Tethys鈩?4192 accepts four
STS-192/STM-64 or sixteen STS-48/STM-16 signals in
either 4 x 2.5 Gbit/s or serial 2.5 Gbit/s format. Further
Tethys provides corresponding functionality in the
DEMUX direction.
