The ATA-175/175P is a two-port FXS voice, fax and modem over IP gateway, which provides user convenient telephony and data service. When network fails, with one port of PSTN backup, ATA-175P can pass calls to PSTN port automatically. ATA-175/175P built-in one WAN port and 4 LAN ports, user can integrate it with original network environment without extra switch or hub. ATA-175/175P’s IP Sharing function allows other computers or devices connect with network more easily.
