(PoP) A site where there exists a collection of telecommunications equipment, usually modem s, digital leased lines and multi-protocol router s. An Internet access provider 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 PoP s (virtual points of presence) via some third party.
