S/UNI®-2488
Preliminary
SATURN® User Network Interface for 2488 Mbit/s
FEATURES
• Single chip ATM and POS UserNetwork 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.

• 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 bidirectional 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.
APSIFP
• 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 3™ 32-bit System Interface
(clocked up to 104 MHz) for Packet
over SONET (POS), or ATM
applications.
