[c-nsp] OT: Ethernet over DS3 or OC3 bridge

[Justin Shore]

Does anyone have any suggestions for a Ethernet to DS3 or OC3 bridge?  I 
need multiple DS3 support for the longer-term but a single DS3 would 
work.  I was looking at the Overture ISG 45 but it appears to only 
support a single DS3.

I couldn't find a DS3 bridge for RAD but I think the Optimux-155 is a 
OC3 bridge.

Basically I need an inexpensive way to transport Ethernet over TDM links 
for an Ethernet venture.  Our transport provider can't do Ethernet at 
this point in time and they've suggested DS3 in the mean time.  DS3 
interfaces are very expensive for 7200s.  I'm thinking a lower cost DS3 
to Ethernet bridge of some sort.  Suggestions?

Thanks
