[Typical Applications]
Reuse of 10/100M IP phone in a Gigabit LAN
Using a PC to record IP Phone calls
Packet Sniffing. Monitoring traffic for a PoE powered Access Point (AP)
Sniffing 802.11 Access Point traffic by using Dualcomm DCGS-2005 USB Powered 5-Port Gigabit Ethernet Switch w/ Port Mirroring and PoE Pass-Through

Dualcomm patent pending 5-Port 10/100/1000Base-T Gigabit Switch TAP (DCGS-2005/DCGS-2005L) can be used as both a 5-Port 10/100/1000base-T gigabit Ethernet switch and a gigabit copper network TAP (Test Access Point). It offers several unique features that  differentiate it from other vendor's products and solutions on the market.

Power over Ethernet Inline Power Pass-Through

DCGS-2005/DCGS-2005L  is  implemented with a set of two ports to facilitate the pass-through  of Power-over-Ethernet (PoE) inline power between these two ports. This is a very useful feature that will allow a DCGS-2005/DCGS-2005L to be placed and connected in between a PoE switch and a PoE powered device such as a PoE enabled IP phone without blocking the PoE inline power from reaching the PoE powered device.

The PoE Inline power pass-through also makes it possible to reuse a 10/100 IP phone in a "Gigabit to Desktop" connection. Otherwise, a  more expensive IP phone with Gigabit ports has to be used to achieve end-to-end gigabit network connection.


DCGS-2005/DCGS-2005L offers a unique and low cost solution for capturing and monitoring network traffic by means of Port-Mirroring. Port-Mirroring used to be a feature found only in much more expensive managed switches requiring manual port configuration, but DCGS-2005/DCGS-2005L makes it plug and play and hassle free without going over your budget.

USB Powered

DCGS-2005/DCGS-2005L is designed to be conveniently powered by a USB port of a computer. To users, this means one less AC/DC power adapter to carry and one less AC outlet to hunt for!
