Semiconductor Solutions for
High Speed Communications
and Fiber Optic Applications
Tethys™ 448 is optimized for SONET/SDH applications
as a full-duplex sixteen STS-48/STM-16 or a mix of sixteen 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 incoming SONET/SDH frame, optionally de scrambles the
data, monitors the TOH and POH, and provides STS-1
level pointer processing. In addition, Tethys™ 448 supports 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 functionality in the DEMUX direction.

PRELIMINARY PRODUCT FLYER
Overview
Tethys™ 448 is a highly integrated device that implements full
duplex SONET/SDH processing at STS-48/STM-16, STS-12/
STM-4 or STS-3/ STM-1 rates. In the rest of this document,
only SONET terminology will be stated. However, SDH terminology applies equally well unless otherwise written.
Tethys™ 448 supports up to 40 Gbit/s bandwidth or 80 Gbit/s
full-duplex. It provides section, line, and path overhead processing and supports framing, scrambling/de scrambling,
alarm signal insertion/detection, bit interleaved parity
(B1/B2/B3) processing, path overhead processing, pointer processing and TOH and POH transparency. It also provides substantial performance monitoring of TOH/POH overhead for
receive direction with 1 second count accumulation.
On the line side, sixteen STS-48’s, or a mix of sixteen
STS-12’s and STS-3’s are supported. The interface utilizes
serial independent 2.5 Gbit/s links, serial independent
622 Mbit/s links or serial independent 155 Mbit/s respectively
for each interface. The STS-48, STS-12 and STS-3 interfaces
can be received at differing clock frequencies, depending on
the SONET line clock variation of ± 20 ppm. Similarly, the
STS-48, STS-12 or STS-3 outputs can be line timed to the
STS-48 inputs.
On the system/client side, sixteen STS-48 can be interfaced.
In this case, serial 2.5 Gbit/s is utilized for the respective interfaces.
The System side can support 16 independent STS-48 links.
The selection/configuration of the system and line side interfaces is completely independent.
All TOH (A1… E2) bytes can be added/dropped onto the parallel TOH/POH interfaces. This applies in both receive and
transmit directions.
All POH passing through the device can be added or dropped
onto the TOH/POH ports. The TOH and POH ports are physically shared.
Detected alarms like LOS, LOF, SEF, AIS-L can be dropped
onto the parallel Alarm Drop Interfaces. This applies in both
the receive and transmit directions. In addition, Tethys™ 448
can drop the payload concatenation configuration onto the
same interface.
In TOH Transparency mode, J0, B1, E1, F1, K1, K2, D1-D12,
S1, M0/M1 and E2 bytes are transparent through the device.
In POH Transparency mode, all POH bytes, including the B3
bytes, are transparent as is. TOH/POH transparency can be
implemented through the TOH/POH ADD/DROP ports using
the dropped overhead and bit error masks on these interfaces.
This applies to both the receive and transmit directions.
Published by Infineon Technologies AG
Tethys™ 448 can process any legal mix of flexible concatenated signals ranging from STS-1, STS-2c, STS-3c … up to
STS-48c. Each set of concatenated signals must fit inside an
STS-3, STS-12 or STS-48 boundary (depending on whether
the pointer processor is configured as an STS-3, STS-12 or
STS-48) and must be formatted as an STS-Nc frame as
defined in GR-253-CORE.
Tethys™ 448 provides the ability for certain frame structures to
be automatically detected and configured into the device. This
feature allows the user to interface to systems with unknown
standard payload concatenation configurations.
Various diagnostic features are provided. Framed PRBS-32
can be generated and checked on any channel via loopbacks.
Errors can be inserted into B1, B2, H1 and H2 bytes on a bitby-bit basis.
To support asynchronous timing between different physical
ports, Tethys™ 448 provides STS-1 level pointer processing
for sixteen STS-48 or a mix of sixteen STS-12 and STS-3
interfaces in the receive direction. On the line side receive
interface, all inputs can be asynchronous with frequency differences of ± 20 ppm.
The pointer processor on the receive side adjusts for these differences and outputs the STS-48, STS-12 or STS-3 streams
based on the line timed or system frequencies selected on the
system side. In the transmit direction, the system side ingress
ports and line side egress ports must be locked to the same
frequency.
Tethys™ 448 aggregates all STS-48 ports from the system
side to the line side in the transmit/multiplex direction. STS-3
and STS-12 rate streams received from the line side are
always multiplexed into the STS-48 rate streams on the system side. In the receive direction, the de-aggregation of physical ports is the reverse of the transmit direction aggregation.
To select the best timing available in the system, the S1 bytes
are processed and the system has the option to select either
timing from the line or timing from the local reference source.
On the system side, the receive outputs can be line timed to
their respective system side transmit inputs.
Tethys™ 448 generates and detects all SONET/SDH relevant
alarms and defects, including LOS, LOF, RDI-L, REI-L, AIS-P,
AIS-L and LOC on each line side and system side interface
PRELIMINARY PRODUCT FLYER
Applications
The application below shows how sixteen STS-48 signals can be connected to a Tethys™ 448 device.
In the transmit direction, Tethys™ 448 performs the
reverse operation.
Tethys™ 448 receives a serial independent 2.5 Gbit/s
format STS-48 frame from the optical device. It then performs framing, performance monitoring, and rate adaptation in the receive direction, and finally outputs a single
STS-48 2.5 Gbit/s differential pair to the STS-48 link
cross connect or the STS-48 optic transceivers.
TOH and POH interfaces may be added and dropped as
required through the respective Tethys™ 448 ports (not
shown).
