No coax goes into Asterisk. Coax is just part of the network build-out
on the last mile for delivering IP to the customer. HFC is the
technology that bridges Ethernet over to a head-end UBR or similar piece
of broadband aggregation equipment over CATV and/or digital.
Imagine that you have an Asterisk PBX colocated somewhere and have a
VoIP handset at home on your DSL connection. The "DSL" part of the
equation doesn't touch either your phone or the PBX per se; it's just a
piece of the abstraction layer and mesh of networks, administrative
domains and physical-layer technologies that deliver IP from Asterisk to
you.
Coax is the same way.
