FEATURES
Single chip ATM and POS User-
Network Interface operating at 2488.32
Mbit/s.
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).
Processes bit-serial 2488.32 Mbit/s
STS-48 (STM-16-16c) data streams
with on-chip clock and data recovery
and clock synthesis.
Complies with Bellcore GR-253-CORE
jitter tolerance, jitter transfer and
intrinsic jitter criteria.
Provides termination for SONET
Section, Line and Path overhead or
SDH Regenerator Section, Multiplexer
Section and High Order Path
overhead.
Provides UTOPIA Level 3 32-bit wide
System Interface (clocked up to
104 MHz) with parity support for ATM
applications.
Provides SATURN POS-PHY
Level 3TM 32-bit System Interface
(clocked up to 104 MHz) for Packet
over SONET (POS), or ATM
applications.
Supports line loopback from the line
side receive stream to the transmit
stream and diagnostic loopback from
the line side transmit stream to the line
side receive stream interface.
Provides support for automatic
protection switching including a bi-
directional 4-bit LVDS 777.76 MHz
port.
Provides a standard five signal IEEE
1149.1 JTAG test port for boundary
scan board test purposes.
Provides a generic 16-bit
microprocessor bus interface for
configuration, control, and status
monitoring.
