PEB1756E - 16 STS-48/STM-16 MUX/DEMUX

General Description

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.

Key Features

  • Provides serial STS-48/STM-16, STS-12/STM-4 or STS-3/STM-1 links.
  • Differential CML 2.5 Gbit/s I/O interface to optics.
  • Differential CML 2.5 Gbit/s I/O interface to system/ backplane.
  • TFI-5 Support.
  • Processes SONET/SDH sixteen STS-48/STM-16 or a mix of sixteen STM-12/STM-4 and STS-3/ STM-1 on the line side interface.
  • Processes SONET/SDH sixteen STS-48/STM-16 on the system/client side serial 2.5 Gbit/s interface.
  • Provides line timing.

P1.0.0 TETHYS™ 448 16 STS-48/STM-16 MUX/DEMUX GENERAL DESCRIPTION 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.
