In the demultiplex ingress direction, Tethys™ PEB1757E accepts either two STS-192/STM-64 or 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™ PEB1757E 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™ PEB1757E supports TOH and POH overhead transparency. In the multiplex direction, Tethys™ PEB1757E accepts sixteen STS-48/STM-16 signals in serial 2.5 Gbit/s format. Tethys™ PEB1757E further provides corresponding functionality in the DEMUX direction.
