An international private leased circuit (IPLC) is a dedicated, point-to-point telecommunications link leased from a communications provider to connect customer sites in different countries, typically not routed over the public internet. In practice, lawyers encounter IPLCs in telecoms procurement, outsourcing and connectivity agreements as leased lines/private circuits carrying data and voice with agreed service levels.
The term is an industry description rather than a term defined in UK or Irish legislation or case law. Regulators treat IPLCs within the broader category of leased line/private circuit services (regulated by Ofcom in the UK and ComReg in Ireland).
Key legal features and contract points include: crossing one or more international borders; end-to-end or segment-based provisioning (often via partner carriers); specified bandwidth and routing; demarcation points; installation and maintenance duties; availability and latency SLAs and repair times; charges, minimum terms and early termination; and security, resilience and lawful-interception compliance. Cross-border carriage may raise additional data-transfer, export control or sanctions considerations depending on the jurisdictions transited.
Usage and meaning are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland, though local regulatory conditions and carrier licensing apply in each jurisdiction.
