Typical applications are for trunking or subscriber access in: • • • Integrated access devices Access multiplexers Next-generation DLC Overview The ZL30226, ZL30227 and ZL30228 form a family of similar devices, differing mainly in the maximum number of serial links, and are collectively referred to as ZL30226/7/8. It should be noted throughout this document whenever reference is made to the number of serial links that the ZL30228 offers a maximum of 16 serial links (links 15:0), while the ZL30227 offers a maximum of 8 serial links (links 14, 12, 10, 8, 6, 4, 2 and 0), and the ZL30226 offers a maximum of 4 serial links (links 12, 8, 4 and 0). Pin and register compatibility has been maintained to offer interchangeability. Note: When creating IMA groups for ZL30226 the groups 0,1,2 and 3 should be used. Description The ZL30226/7/8 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 ZL30226/7/8 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 ZL30226/7/8 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 simultaneously, the ZL30226/7/8 device provides the ideal architecture and capabilities. The device 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 ZL30226/7/8 device and software functions are implemented by the IMA Co.
