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.
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.
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.
Implemented in 1.2 V core and 2.5 V
I/O 0.13μm CMOS technology. Inputs
are 3.3 V tolerant.
Packaged in a 672-ball FCBGA
top-hat, 27 mm x 27mm.
