point of presence

(PoP) A site where there exists a collection of

telecommunications equipment, usually modems, digital leased

lines and multi-protocol routers. An Internet accessprovider may operate several PoPs distributed throughout

their area of operation to increase the chance that their

subscribers will be able to reach one with a local telephone

call. The alternative is for them to use virtual PoPs

(virtual points of presence) via some third party.
