GENERAL DESCRIPTION

• The S/UNI-9953 is a single chip ATM, POS and 10 Gigabit Ethernet User Network Interface operating at 9953.28 Mbit/s and 10.3 Gbit/s. The S/UNI 9953 is intended for use in OC-192c and high-density OC-48c POS/ATM applications as well as 10 Gigabit Ethernet WAN and LAN PHY port cards.

FEATURES

• Provides WAN Interface Sub-layer (WIS), Physical Coding Sub-layer (PCS), and Media Access Controller (MAC) functionality for OC-192c rate 10 Gigabit Ethernet WAN PHY datastream.

• Provides PCS and MAC layer functionality for 10.3 Gbit/s 10 Gigabit Ethernet LAN PHY datastream.

• 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).

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.

• Low power 1.8 V CMOS core logic with 3.3 V CMOS/TTL compatible digital inputs and digital outputs.

• Industrial temperature range (-40 °C to +85 °C).

• 1152 pin FCBGA package.

APPLICATIONS

• Edge and Core Routers.

• Multi-Service (Multi-Protocol) Switches.

• Internet POP and Transport POP L2 Ethernet Switches.

• SONET/SDH add/drop multiplexers and optical cross-connects.

• WAN and Edge ATM switches.

• Up-link cards.

• SONET/SDH ATM/POS and 10 Gigabit Ethernet test equipment.

• Emerging DPT, IPT, and GFP applications.
