PM5392 S/UNI®-9953-POS Advance SATURN® User Network Interface for 9.953 Gbit/s 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 OC192c and high-density OC-48c POS/ATM applications. • 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). INTERFACES • 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 16bit 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. • 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. 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).
