[asterisk-biz] Anyone experienced in cable telephony?

[C. Savinovich]

 Excellent, exactly what I wanted to figure out.  So I assume that the good
cable telephony service provided by say Optimum, which provides a telephony
service basically independent from its internet service, is due to basically
the setup of a VLAN, with say Cisco routers, just like any other VLAN
partitioning rules...  in other words...there is no special model Cisco
equipment specific to partitioning cable networks and telephony networks,
that I should know of?

Usually when you run a cable network, this is a bus wired system, there is a
main trunk line with passive splitters or "taps" these taps bleed off a
small amount of the total power available for a street or neighborhood,
these larger cables are also pulled together similarly in some instances or
with active equipment. Once it makes it to the head end, a box pulls off the
IP network signals and converts it to Ethernet so you can then pull it right
into asterisk or send the media to TDM media gateways with out too much
trouble
