virtual point of presence การใช้

By the spring of 1996, competition among the ILEC and CLECs was getting rough, and the phone companies began to offer virtual points of presence : they would trunk in phone lines to a central location which offered a telephone prefix which was local to various other parts of the city, which allowed customers to dial into a phone line which was in their local ( untimed ) calling radius without forcing the ISPs to operate remote POPs, physical offices with networking gear and modems, in various places around the city just to be able to offer customers local dialin numbers.
