PRELIMINARY PRODUCT FLYER
Overview
TethysTM 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. TethysTM 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, TethysTM 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. TethysTM 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. TethysTM 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, TethysTM 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. TethysTM 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. TethysTM 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

Applications
The application below shows how sixteen STS-48 signals can be connected to a TethysTM 448 device. TethysTM 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. In the transmit direction, TethysTM 448 performs the reverse operation. TOH and POH interfaces may be added and dropped as required through the respective TethysTM 448 ports (not shown). Many other configuration options are possible that cannot be shown in this diagram. Please refer to the data sheet for more detailed information.
