Editing Leased line (section)

===In Italy===
In [[Communications in Italy|Italy]], leased lines are available at speeds of 64&nbsp;kbit/s (terminated by DCE2 or DCE2plus modem) or multiple of 64&nbsp;kbit/s from 128&nbsp;kbit/s up to framed or unframed E1 (DCE3 modem) in digital form (PDH service, known as CDN, ''Circuito Diretto Numerico''). Local [[telephone company|telephone companies]] also may provide CDA (''Circuito Diretto Analogico''), that are plain copper [[dry pair]] between two buildings, without any line termination: in the past (pre-2002) a full analog base band was provided, giving an option to customer to deploy xDSL technology between sites: nowadays everything is limited at 4&nbsp;kHz of bearer channel, so the service is just a [[plain old telephone service|POTS]] connection without any setup channel.

For many purposes, leased lines are gradually being replaced by [[DSL]] and [[metro Ethernet]].
