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