Product Overview

Features

  • Implements a single chip 12-channel ATM or a bit- HDLC User Network Interface operating at 44.736 Mbit/s, 34.368 Mbit/s, and 6.312 Mbit/s. As an ATM interface, it conforms to ATMF-95-1207R1, ATMF-94-0406R5, and AF-PHY-0029.000. For either interface, each line of the S/UNI 12xJET can be individually configured for the desired rate and data formats.
  • Implements a single chip ATM and packet process capable of processing rates up to STS-12c/STM-4-4c payloads.
  • Synchronizes and desynchronizes DS3 and E3 serial streams to or from SONET/SDH payloads, accommodating plesiochronous timing offsets between the line and system timing references, through appropriate processing of bit stuffing and (for desynchronization) pointer movements.
  • Provides a duplex 8-bit 77.76 MHz STS-12/STM-4 line side interface for direct connection to external clock recovery, clock synthesis and serializer-deserializer components.
  • Provides a duplex 8-bit 77.76 MHz TelecomBus-compatible interface, which may be combined with three other S/UNI 12xJET devices to form a 32-bit 77.76MHz STS-48/STM-16 TelecomBus compatible interface.
  • Provides support for SMDS, bit-HDLC and ATM mappings into T3, E3, J2, E1, T1 and arbitrary cell rate transmission systems.
  • Provides termination for SONET Section, Line and Path overhead or SDH Regenerator Section, Multiplexer Section and High Order Path overhead.
  • Implements the ATM Forum User Network Interface Specification and the ATM physical layer for Broadband ISDN according to CCITT Recommendation I.432 on arbitrary SONET/SDH payloads including STS- 1/STM-0/STS-3c/STM-1/STS-12c/STM-4-4c payloads.
  • Implements the Point-to-Point Protocol (PPP) over SONET/SDH specification according to RFC 2615 and RFC 1662 on arbitrary STS-1/STM-0 payloads.
  • Implements ATM Direct Cell Mapping into DS1, DS3, E1, E3, and J2 transmission systems according to ITU-T Recommendation G.804.
  • Implements bit HDLC Mapping into DS1, DS3, E1, E3, and J2 transmission systems according to ITU-T Recommendation G.804.
  • Implements the Physical Layer Convergence Protocol (PLCP) for DS1 and DS3 transmission systems according to the ATM Forum User Network Interface Specification and ANSI TA-TSY-000773, TA-TSY- 000772, and E1 and E3 transmission systems according to the ETSI 300-269 and ETSI 300-270.
  • Provides on-chip DS3, E3 (G.751 and G.832), and J2 framers.
  • May be configured to be used solely as a DS3, E3, or J2 Framer.
  • Compatible with PMC-Sierra T1/E1 frame/line interface chips for DS1 and E1 applications.
  • Provides programmable pseudorandom test pattern generation, detection, and analysis features.
  • Provides integral transmit data link and receive data link HDLC controllers with 128-byte FIFO depths for each serial channel.
  • Provides support for an arbitrary rate external transmission system interface up to a maximum rate of 52 Mbit/s, which enables any mix of the S/UNI 12xJET's 12 channels for bit-HDLC processing or ATM cell delineation.
  • Provides performance-monitoring counters suitable for accumulation periods of up to 1 second.
  • Provides a 16-bit microprocessor interface for configuration, control and status monitoring.
  • Provides a standard 5-signal P1149.1 JTAG test port for boundary scan board test purposes.
  • Low power 3.3 V / 1.8 V CMOS technology with 5 V tolerant inputs.
  • Available in a high density 580-pin TSBGA package (35 mm x 35 mm) with 1 mm ball pitch.
  • Typical Applications include:

  • Multi-service, ATM, SMDS switches, multiplexers and routers.
  • SONET/SDH Mux E3/DS3 tributary interfaces.
  • PDH Mux J2/E3/DS3 line interfaces.
  • J2/E3/DS3 Digital Cross Connect interfaces.
  • J2/E3/DS3 PPP Internet Access interfaces.
  • J2/E3/DS3 Frame Relay interfaces.
  • SONET/SDH ADMs with data processing capabilities.
  • Channelized OC-12 line interfaces in IP routers and Multi-service switches.
