A promising next-generation version of service that could be availed from local exchange carriers (LECs) refers to streaming Internet protocol based television (IPTV) programs into subscriber premises via traditional copper pairs.;The present study addresses provisioning economically-budgeted and optimally-engineered bit rates (EBRs) in implementing IPTV technology in the local-loop via copper-pairs using the so-called (ADSL2/ADSL2+) technology (with high-speed/large bandwidth considerations plus copper-bonding for bandwidth sharing capabilities). Also studied is the way to extend the backhaul transport of IPTV on copper-lines (plus any other local-loop transmissions that may co-exist) onto an "all-optical" trunk of the inter-office facilities (IOFs) in the edge/core network cloud of the telcos. A model of a core network topology is analyzed for traffic considerations so as to decide on blocking probability at a specified egress node under different conditions of burstiness. The problems posed are analyzed via computations/simulations on Matlab(TM) (v6.5). Inferential remarks are gathered, conclusions are drawn and open-questions yet to be researched are indicated.
