GENERAL DESCRIPTION

? The S/UNI-9953-POS is a single chip ATM, POS User-Network Interface operating at 9953.28 Mbit/s. The S/UNI 9953-POS is intended for use in OC-192c and high-density OC-48c POS/ATM applications.

FEATURES

? Supports framing, scrambling/

descrambling and pointer processing

for the following:

? STS-192c (STM-64-64c).

? 4 x STS-48c (4 x STM-16-16c).

? STS-192 (STM-64) channelized

down to STS-48c (STM-16c).

? Supports alarm signal

insertion/detection, B1/2/3 processing

and insertion/termination of SONET

Section/Line/Path overhead bytes (or

SDH equivalents).

? Provides ATM and POS payload

processing for:

? STS-192c (STM-64-64c)

? 4 x STS-48c (4 x STM-16-16c).

? STS-192 (STM-64) channelized

down to STS-48c (STM-16c).

INTERFACES

? Provides SATURN? POS-PHY?

Level 4 16-bit LVDS System-side

Interface (clocked at 700 MHz

nominal).

? Directly connects to optics via 16 bit by

622 MHz OIF SFI-4 (OIF99.102) lineside interface.

POS/ATM

? Implements the ATM Forum User

Network Interface Specification and

the ATM physical layer for Broadband

ISDN according to CCITT

Recommendation I.432.

? Implements the Point-to-Point Protocol

(PPP) over SONET/SDH specification

according to RFC 2615(1619)/1662 of

the PPP Working Group of the Internet

Engineering Task Force (IETF).

GENERAL

? Provides internal FIFOs (16 KB

ingress, 20 KB egress) to

accommodate system latencies.

? Provides line-side and system-side

loopbacks for system level diagnostic

capability.

? Provides support for automatic

protection switching (APS) via two 16-

bit LVDS 777.76 MHz ports.

? Provides a generic 16-bit

microprocessor bus interface for

configuration, control and status

monitoring.

? Standard 5 signal P1149.1 JTAG test port.

? Low power 1.8 V CMOS core logic with

3.3 V CMOS/TTL compatible digital

inputs and digital outputs.

? Industrial temperature range (-40 °C to

+85 °C).

? 1152 pin FCBGA package.

APPLICATIONS

? Edge and Core Routers.

? Multi-Service (Multi-Protocol) Switches.

? SONET/SDH add/drop multiplexers and optical cross-connects.

? WAN and Edge ATM switches.

? Up-link cards.

? SONET/SDH ATM/POS test equipment.

? Emerging DPT, IPT and GFP applications.
