Hi All,
I have implemented Cable and DSL service providers and have seen =
that they use their own separate backbone.=20
The backbone for most cable ISP's is Hybrid Fiber Coax (HFC) where fiber =
will be laid from Headend till the nodes and nodes connects to customers =
using co-axial lines.
The backbone for DSL Service Providers is fiber which will be connected =
to DSL Access Multiplexers, which inturn connect to customers using =
twisted pair (layer 2 =3DATM).=20
In both the above cases the fiber backbone is common.=20
My question: Is it possible for a service provider to provide both Cable =
& DSL services through the same Fiber? Is it implemented anywhere ?
Regards,
Vamsi
