WSE 20

Released

SONET/SDH Wideband Cross-Connect

container of VT/TUs. The contents

may be switched intact or switched as

VT/TUs.

• Provides fully automatic protection

FEATURES

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.

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.

• 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 and

6.21 (+/-0.67) µs for 622 Mbit/s links.

I/O AND GENERAL

• All high-speed ingress and egress links

are 1.2 V CML and are ELVDS-

compatible 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.

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.

• 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.

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.

• Provides a standard 5-signal IEEE

1149.1 JTAG test port for boundary

scan test purposes.

• Each SONET STS-1 or SDH

VC3/VC4-TUG3 may be independently

configured as a single unit and/or as a
