What would be needed in an SR last mile model is a substitute for the cable modem, in the way of an RF insertion/extraction transducer, miniaturized, of course, down to the size of a Reader's Digest, with RF and 100 BaseT Ethernet interfaces for premises appliances.
The element labeled "Fiber" below, shown between the head end and the home, would actually be a ring, one of whose tenants was another head end for redundancy purposes, as you noted.
The home transducer would take in fiber from the field, and import/export RF-modualted data of various forms, and it would optionally provide a Fast Ethernet interface connection via an 8-pin modular Cat 5 jack (RJ-45) for premises routers and PCs. The transducer would containt sufficient DSP smarts, and an additional RJ-11/12, to collectively support a voice telephony demarcation point:
'Net>-->HE-->Fiber-->Home-->Transducer-->RF I/O's and RJ45s-->Appliances

I hesitate to show SR on the left hand side of the router at this stage. That would be overly presumptuous, even more so than that which I've shown.
Something along these lines? If not, reply in kind. |
