LONDON -- The ATM Forum Technical Committee has approved the UTOPIA Level 4 frame-based interface specification, which raises the speed of the ATM frame-based interface up to 10G rate. This is an important step in the development of ATM; the fastest data rate available today is 2.4Gbps. Several projects are currently in development which incorporate the UTOPIA Level 4 specification.

"Service Providers will be able to utilize a switch backbone that can be used with interchangeable linecards, allowing for 10Gbit pipes, Wave Division Multiplexing (WDM) up to 10Gbps and multiport linecards of up to 10Gbps," explains the ATM Forum's John Mick, Technical Chair, Physical Layer Group.
