ZL30226/7/8
4/8/16 Port IMA/TC PHY Device for xDSL
Data Sheet
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
1. ZL30226 supports up to 4 serial links with maximum 4 groups
to be used - groups 0, 1, 2, 3.
ZL30227 supports up to 8 serial links
ZL30228 supports up to 16 serial links
