HI AIX-Experts

I've got a Q.:

Info Explorer say's :
The Turboways 100 adapter provides 100 Mbps, full duplex connectivity for
Micro-Channel Bus-based
servers or clients using permanent virtual circuits (PVCs) and switched
virtual circuits (SVCs). The PVC
and SVC implementation is compliant with "ATM Forum UNI 3.0" specification.
 Similarly, Turboways 155
adapters provide 155 Mbps, full duplex connectivity to ATM networks. The
adapters support a maximum
 of 1024 virtual circuits.

atmstat -d atm0 say's :


General Statistics:
-------------------
No mbuf Errors: 0
No mbuf Errors: 0
Adapter Loss of Signals: 0
Adapter Reset Count: 0
Driver Flags: Up Running Simplex
Virtual Connections in use: 4
Max Virtual Connections in use: 7
Virtual Connections Overflow: 0

And now my question : Adapter is able to run duplex, NDD is running simplex
 ???
Why ? Is it important to performance ? How to change it ?

regards and thanx for any help
