TDM (E1) transport over ATM AAL1

Hi, I am starting to develop a project for TDM
transport (E1 at 2048k bits/sec) over ATM AAL1 using
embedded linux on PowerPC.
This application is defined in the ATM FORUM
specification 'af-vtoa-0078.000' (Circuit Emulation
Service Interoperability Specification)
I would like to know if anyone has experienced this
kind of application.
I am worried about the PowerPC performance, it would
have to route about 5.5k ATM AAL1 cells/sec, and the
adaptative clock recovery method.

Regards,
Robert.
