TETHYS™ 4192 QUAD STS-192/STM-64 MUX/DEMUX
GENERAL DESCRIPTION
Tethys™ 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 ag-
gregation, ADM and DWDM applications. In the de-
multiplex ingress direction, Tethys™ 4192 accepts
four STS-192/STM-64 signals in SFI-4.2/SFI-4.1 for-
mat. Tethys locates the incoming SONET/SDH
frame, optionally de-scrambles the data, monitors the
TOH and POH, and provides STS-1 level pointer pro-
cessing. In addition, Tethys supports TOH and POH
overhead transparency.
In the multiplex direction, Tethys™ 4192 accepts four
STS-192/STM-64 or sixteen STS-48/STM-16 sig-
nals in either 4 x 2.5 Gbit/s or serial 2.5 Gbit/s format.
Further Tethys provides corresponding functionality
in the DEMUX direction.
