You know you shouldn't (can't?) use the same interface for regular IP 
networking and TDMoE, right?  The TDMoE should have an address-less NIC 
to itself and _really_ shouldn't run through a hub (an xover would be 
ideal).  Bonding seems possible, since the bonding is done at a lower 
level than Asterisk knows about and just creates a virtual device.  
Because both sides just see one NIC with one MAC, the only problem I 
could anticipate would be increased latency, but I doubt it's as 
significant as the latency a switch creates.
