Overview
The VSC9116 is an STS-192/STM-64 SONET/SDH transport overhead terminating transceiver. It may be used for combining four STS-48/STM-16 data streams at the drop side interface into a single STS-192/STM-64 data stream at the line side or passing through an STS-192/STM-64 data stream. The primary functional blocks in the VSC9116 include: an industrial compliant 16-bit, 622 MHz SONET- /SDH line interface (OIFSF-4), SONET/SDH section/line generation and termination of the STS-192/STM-64 line signal in compliance with ANSI, Bellcore, and ITU specifications, 4x4 cross-connection of any of the STS-48/STM-16 data streams in both transmit and receive direction, enhanced buffer capabilities for de-skewing STS-48/STM-16 data streams, SONET/SDH section generation and termination of the STS-48/STM-16 drop signals, four 4-bit (622 MHz mode) or 16-bit (155 MHz mode) SONET/SDH drop interfaces, dedicated ports for STS-192/STM-64 section/line overhead access of line interface data stream, dedicated ports for STS-48/STM-16 section overhead access of drop interface data streams, flexible synchronization of the STS-48/STM-16 drop devices, enhanced bit error rate monitoring of STS- 192/STM-64 line signal, an 8-bit microprocessor interface with 8 general purpose I/O ports, JTAG TAP controller. When combined with a high-speed mux/demux transceiver, this device provides a complete solution for migrating STS-48/STM-16 to STS-192/STM-64 interfaces in SONET/SDH, ATM, or POS applications.
