Tethys™ 448 is optimized for SONET/SDH applications
as a full-duplex sixteen STS-48/STM-16 or a mix of six-
teen STS-12/STM-4 and STS-3/STM-1 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™ 448 accepts either 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™ 448 locates the incom-
ing SONET/SDH frame, optionally de scrambles the
data, monitors the TOH and POH, and provides STS-1
level pointer processing. In addition, Tethys™ 448 sup-
ports TOH and POH overhead transparency.
In the multiplex direction, Tethys™ 448 accepts sixteen
STS-48/STM-16 signals in serial 2.5 Gbit/s format.
Tethys™ 448 further provides corresponding functional-
ity in the DEMUX direction.
