Editing Leased line (section)

==Leased line alternatives==
Leased lines are more expensive than alternative connectivity services including ([[ADSL]], [[Symmetric digital subscriber line|SDSL]], etc.) because they are reserved exclusively to the [[leaseholder]]. Some internet service providers have therefore developed alternative products that aim to deliver leased-line type services ([[carrier Ethernet]]-based, zero contention, guaranteed availability), with more moderate bandwidth, over the standard UK national broadband network. While a leased line is [[full-duplex]], most leased line alternatives provide only [[half-duplex]] or in many cases asymmetrical service.
