Ethernet support for MII interface
Support for Ethernet MIB
ATM using twin UTOPIA interfaces allow secondary data SAR to be daisy-chained with device for data
connections
Packet over SONET support for 16-bit POS-PHY bus allowing interoperation with PHY at speeds up to 155
Mbps
Support for packets of up to 1500 bytes (plus MAC header) in Ethernet and up to 65535 bytes in ATM and
Packet Over SONET
Secondary UTOPIA port can be used in all modes allowing the same data support architecture to be used
independently of the link layer with minimal changes
Transmission of voice to secondary port allows H.110/PCM bridging when coupled with AAL5 SAR
Pin-out allows designs that support Ethernet, ATM and Packet over SONET with only software configuration
deciding on the link layer used
