If your job includes frequent testing of Gigabit Ethernet links and PoE ports that supply power to VoIP phone systems, then you need the BLACK BOX Veri-Net VoIP. This advanced tester offers Gigabit- over-copper-link testing as well as VoIP/PoE detection. It even measures the voltage supplied by the VoIP or PoE port to ensure that it's adequate. In addition to verifying whether there's correct power, the Veri-Net VoIP also detects and transmits Link signals, testing the VoIP or PoE port to determine the speed and duplex mode. If there's a duplex mismatch between equipment ports, you'll know it. And, so you can accurately map your network, the tester enables you to identify which port on a connected hub or switch corresponds to a particular wall outlet.Just insert the Veri-Net VoIP's plug into the RJ-45 port of a hub, switch, network interface card (NIC) or wall outlet and press its TEST button. The tester then begins scanning the wire pairs for voltage. An included RJ-45 coupler enables you to attach the tester to a UTP or an STP cable.
