FEATURES

GENERAL

? 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 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.

? Provides a device latency of 5.62 (+/-0.17) μs for 2.488 Gbit/s links and 6.21 (+/-0.67) μs for 622 Mbit/s links.
