IP over ATM overhead

[Stephen Balbach <stephen () clark net>]

We are installing an ATM backbone connection and wondering what level 
of overhead can be expected. Ive read from %10 to %50 - this will be a 
LAN connection so we can assume almost no cell loss. Our provider has 
said on average %12 bandwidth is overhead. It will be a Cisco->Cisco LAN 
configuration. Thanks!
