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) µs for 2.488 Gbit/s and
6.21 (+/-0.67) µs for 622 Mbit/s links.
PM5389
WSE 20
• 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 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.
• 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.
