The network infrastructure accounts for a significant portion of installation costs. Most SIP telephony systems rely on Power over Ethernet (PoE) using Cat5 cables. While this may seem like a simple and appealing solution, it comes with several drawbacks. PoE systems require costly PoE switches, an expensive 48-volt power backup, and a star-wiring configuration for the area stations.
Our goal was to eliminate the need for PoE switches and avoid the star-wiring architecture, helping to reduce costs. Instead of connecting area stations directly to Ethernet, installers can opt for a network interface card that allows both communication and power to run over a 4-wire cable. Up to seven stations, plus one separate network card, can be connected in a single loop.
For example, if you have two area stations on two different floors, all you need is: 2 SIP-SNAP stations with network cards, 1 separate network card, a 4-wire cable, an Ethernet cable connecting the separate network card to the switch, and a 24-volt power supply with backup.
