Everybody wants high speed internet access.
Monopolies die hard.
An ILEC can supply a splitter and provision ADSL over an existing line, but until recently, customers who brought their business to a CLEC were forced to pay for an additional phone line. Extra charges sting on a monthly basis, but more frustratingly, the extra hoop can necessitate a pointless wait for installation of an additional circuit. ADSL already supports analog voice frequencies by allocating digital data communications to higher frequencies, but VoDSL takes an alternate tack. VoDSL converts voice from analog to digital format, sending voice as just a fraction of its digital load. G.lite is generally considered unsuitable for the task.
