Multiple models offer flexibility for varied applications from pri delivery and SIP trunking services to hosted IP PBX offerings. The total access 900E Series offers up to 24 fxs ports for analog Voice delivery, and three Ethernet interfaces (one Gigabit and two fast) for access to the total access 900e's router or WAN/LAN access. The total access 900E Series can be coupled with a NetVanta power over Ethernet (PoE) switch to provide connectivity to a variety of network devices and personal computers, as well as to power IP phones and wireless access points (waps).
