Description



Features:

IMA
• Up to 16 xDSL links & up to 8 IMA groups with 1 to 16 links/IMA group1
• Supports symmetrical & asymmetrical operation
• CTC (common transmit) & ITC (independent transmit) clocking modes
• Pre-processing of RX ICP (IMA control protocol) cells
• IMA layer & per link statistics and alarms for performance monitoring with MIB support TC and UNI
• Supports mixed-mode operation: links not assigned to an IMA group can be used in TC mode
• ATM framing using cell delineation
• HEC (header error control) verification & generation, error detection, filler cell filtering (IMA) and idle/unassigned cell filtering (TC)
• TC layer statistics and error counts i.e. HEC errors with MIB support Standards Compliant
• ATM Forum - IMA 1.1 (AF-PHY-0086.001) & backwards compatible with IMA 1.0
• ITU G.804 cell mapping & ITU I.432 cell delineation



Application

Provides cost effective solutions to implement IMA and/or TC functions over xDSL transport facilities in broadband access networks. Typical applications are for trunking or subscriber access in:
• Integrated access devices
• Access multiplexers
• Next-generation DLC




Description

The ZL30226/7/ZL30228 device is targeted to systems implementing the ATM FORUM Inverse Multiplexing for ATM (IMA version 1.1 and 1.0) or UNI specifications. In the ZL30226/7/8 architecture, up to 16 physical and independent serial links can be terminated through the utilization of off-the-shelf xDSL chip sets. The ZL30226/7/8 can provide up to 10 Mb/s per link data rates for TDM serial transmissions for xDSL applications.

The ZL30226/7/ZL30228 device provides ATM system designers with a flexible architecture when implementing ATM access over existing line interfaces, allowing a migration towards ATM service technology. The ZL30226/7/ZL30228 device is compliant with the ATM FORUM IMA specifications for controlling IMA groups of up to 16 lines in a single chip. The ZL30226/7/8 can be configured to operate in different modes to facilitate the implementation of the IMA function at both CPE and Central Office sites. For systems targeting ATM over DSL with IMA and TC operating imultaneously, the ZL30226/7/8 device provides the ideal architecture and capabilities.

The ZL30228 provides up to 8 internal IMA processors and allows for bandwidth scaleability through the use of the UTOPIA MPHY, Level 1 and Level 2 specification at rates up to 52 Mhz.

The implementation of IMA as per AF-PHY-0086.001 Inverse Multiplexing for ATM (IMA) Specification Version 1.1 is divided into hardware and software functions. Hardware functions are implemented in the ZL30226/7/ZL30228 device and software functions are implemented by the IMA Core (Zarlink or user) software. Additional hardware functions are included to assist in the collection of statistical information to support MIB implementation.
