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. -- Alex Balashov Evariste Systems Web : http://www.evaristesys.com/ Tel : (+1) (678) 954-0670 Direct : (+1) (678) 954-0671 Mobile : (+1) (678) 237-1775 _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
