A gateway is a network device used to provide access between different types of networks. For instance, a gateway may provide access into an external network such as the PSTN, the Internet, or a pm WAN. A PSTN gateway has a LAN inter/ace on the inside and a PRI access transport line on the outside. It translates IP telephony frames into circuit-switched POTS traffic for the PSTN and vice versa.
