I notice Cisco's new ME4600 ONT's come in two flavors, one (the
"Residential GateWay") with all the bells and whistles that you'd expect in
an all-in-one home router (voice ports, small ethernet switch, wifi access
point) and another (the "Single Family Unit") that looks a lot more basic
and is likely to be deployed as a bridge.
