Engineering:Point of presence
A point of presence (PoP) is an artificial demarcation point or network interface point between communicating entities. A common example is an ISP point of presence, the local access point that allows users to connect to the Internet with their Internet service provider (ISP).[1] A PoP typically houses servers, routers, network switches, multiplexers, and other network interface equipment that connects an ISP to customers including OLTs (optical line terminals) for fiber internet,[2] and is typically located in a data center. ISPs typically have multiple PoPs. PoPs are often located at Internet exchange points and colocation centres.[3]
In the US, this term became important during the court-ordered breakup of the Bell Telephone system. A point of presence was a location where a long-distance carrier (IXC) could terminate services and provide connections into a local telephone network (LATA).[4]
