Dualcomm’s patent pending 10/100/1000Base-T gigabit network TAP (DCGS-2005) is a portable hardware device for capturing bi-directional inline traffic of an Ethernet link segment. It is usually used for network intrusion detection systems, VoIP recording, network probes for monitoring and trouble-shooting, and etc. DCGS-2005 implements PoE inline power pass-through between two inline ports, which allows DCGS-2005 to be placed inline between a PoE switch and PoE powered device such as an IP phone or access point without blocking the POE inline power from the PoE switch to reach the PoE powered device. DCGS-2005 is also designed to be conveniently powered by a USB port so that an otherwise heavy and bulky AC/DC power adapter becomes not necessary! DCGS-2005 can also function as a 5-port Gigabit Ethernet Switch.
