Product Overview



  • Multi-purpose SONET/SDH VT/TU and SONET/SDH STS/STM cross-connect.
  • With a memory-switch architecture, implements a strictly non-blocking switch that supports a VT/TU level fabric of up to 45 Gbit/s.
  • Supports 18 high-speed Enhanced SONET Serial Interface (ESSI) CML links each independently configurable for STS-48/STM-16 at 2.488 Gbit/s or STS-12/STM-4 at 622.08 Mbit/s operation.
  • Supports 12 low-speed links operating at 51.84 Mbit/s. The frame alignment of the low-speed links is independent of the high-speed links.
  • Supports system frame synchronization using an external frame pulse or ESSI smart frame synchronization using the frame boundary of the receive links.
  • Compensates for differences in frame boundary arrival times between ingress ports using FIFOs and device level software configurable delay registers.
  • Each SONET STS-1 or SDH VC3/VC4-TUG3 may be independently configured as a single unit and/or as a container of VT/TUs. The contents may be switched intact or switched as VT/TUs.
  • Allows each SONET VT Group to be independently configured to carry VT1.5, VT2, VT3, or VT6 tributaries.
  • Allows each SDH TUG2 to be independently configured to carry TU11, TU12, or TU2 tributaries.
  • Typical Applications include:

  • SONET/SDH Add-Drop Multiplexer (ADM).
  • SONET/SDH Digital Cross-connect (DCC).
  • Multi-service Provisioning Platform (MSPP).
  • Multi-service ADM (MS-ADM).
  • Multi-service Switch (MSS).
  • Optical Access Mux.
  • Terminal Multiplexers.
