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-PHYTM
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) line-
side 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.
