Dsl Splitter / Filter

From where could i purchase a DSL Splitter/Filter. . ?

Does it do any wonders on the PTCL DSL Service?

it only splits!

yes you can have one free of cost from your exchange

thanx

regards

It's sad that we don't have POTs Filter here in pak to cancel noise in phones and it also helps in increasing SNR Margin for xDSL
