FEATURES
High performance backplane interface
and cross-connect for 2.5G line cards in
SONET/SDH systems.
Provides one low-speed parallel
TelecomBus interface operating at
32 bits x 77.76 MHz.
Provides three high-speed multi-rate
serial backplane interfaces.
Supports CLOS and memory-based
switch fabric systems.
Supports linear, UPSR, and BLSR
protection strategies.
SWITCHING CAPACITY
Implements a 10G memory switch fabric
with STS-1/AU-3 switching granularity in
a single device.
Supports non-blocking anycast switching
between any of the serial or parallel
interfaces.
Provides two pages of connection
memory with software and hardware
controlled hitless page swaps at frame
boundaries.
Provides integrated delay management
that allows for arbitrary SONET/SDH
frame alignments on each ingress serial
link.
SERIAL PORT FUNCTIONS
Supports three RASIO 3G high-speed
serial backplane interfaces for interfacing
with SONET/SDH cross-connects,
framers, mappers, and other
TBSTM 2488 devices.
Each high-speed serial backplane
interface is capable of independent
operation at 4x622 Mbit/s scrambled
NRZ SONET/SDH, 4x777 Mbit/s Serial
TelecomBus, or 1x2488 Mbit/s
scrambled NRZ SONET/SDH.
High-speed serial RASIO compatible
with CML, LVDS, and LVPECL.
Supports nibble and di-bit slicing on
622 Mbit/s links for sliced switching
architectures.
PARALLEL PORT FUNCTIONS
Supports one 32-bit or four 8-bit
77.76 MHz TelecomBus interfaces to
interface with parallel TelecomBus
framers and mappers.
Integrated pointer interpreter reduces
complexity of external framers and
mappers by asserting payload, J0, and
J1 indications on the outgoing
TelecomBus interface.
Allows insertion and extraction of TOH
bytes through a dedicated low speed
serial interface.

TYPICAL APPLICATIONS
Provides Bit Error Rate (BER) monitoring
for all paths received on the TelecomBus
interface.
Detects signal degrade (SD-P) and signal
fail (SF-P) threshold crossing alarms
based on received B3 errors on the
TelecomBus interface.
ESSI FUNCTIONS
Automatically frames to the incoming
links based on standard A1/A2 framing.
Provides in-service link verification via bit
interleaved parity (BIP-8) of the B1 byte.
Optionally generates B1 byte on egress
flows.
Provides out of frame alignment status
information for each ingress port.
Provides per-link SONET-framed and
unframed PRBS-23 generation and
monitoring for off-line link verification.
Supports frame synchronization using
ESSI smart framing or a global frame
pulse input signal.
Compensates for in frame boundary
arrival times between serial interfaces
using FIFOs and device level software
configurable delay registers.
GENERAL

monitoring.
Standard 5-signal IEEE 1149.1 JTAG test
port for boundary scan board testing.
APPLICATIONS
