even if this is the case a 15mb line is overkill for all above usage
My ISP charges my mother the same price for 5 Mbps Internet at her residence as they charge me for 15 Mbps at mine; less the stupid $6.50 modem rental fee they started collecting last year. No tiers, just a limit due to DSL and wireline distance. -- Norman ~Oh Lord, why have you come ~To Konnyu, with the Lion and the Drum
Fusion℠ delivers our fastest residential broadband at up to 20Mbps and traditional home phone service with unlimited nationwide calling all for a single low price $39.95+$6.95 modem fee. and is not an intro rate according to the site.
home phone on TWC alone = $39.95 a month 15Mb line is $54 a month + modem 3Mb line is $39.95 + modem a month if not mistaken
so i would take a 5Mb line and home phone at that rate
the same level of phone service on ATT or verizon = $70+ a month.
