| Released SONET/SDH Wideband Cross-Connect 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 25 Gbit/s. * Supports 10 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) s for 2.488 Gbit/s and 6.21 (+/-0.67) s for 622 Mbit/s links. PM5389 WSE 20 www..com * Provides fully automatic protection switching for Class 1 protection services including 1+1 protection, UPSR, SNCP, and static mesh protection services. * Provides hardware assists for Class 2 protection services including 1:N protection, BLSR-2/4, MSSPRING-2/4, and dynamic mesh protection schemes. I/O AND GENERAL * All high-speed ingress and egress links are 1.2 V CML and are ELVDScompatible with programmable pre-emphasis on transmit, equalization on receive, and support for both AC and DC coupled interfaces. * Each high-speed link supports SONET/SDH framed or unframed PRBS-23 or PRBS-7 generation and monitoring for off-line link verification. * Configured, controlled, and monitored using a generic 32-bit microprocessor interface. * Provides a standard 5-signal IEEE 1149.1 JTAG test port for boundary scan test purposes. SONET/SDH OVERHEAD ACCESSIBILITY * Supports extraction of the transport overhead (TOH) from the ingress ports (both high and low-speed) as well as the insertion of transport overhead into the egress ports via low bandwidth two-bit 77.76 MHz interfaces. APS FEATURES * Supports a hardware-based Automatic Protection Switching mechanism (MAPS) for centralized link protection control when operating with other PMC-Sierra devices such as the PM5369 TUPP 9953.
