USB Powered 5-Port Gigabit Desktop Switch with
Port-Mirroring & PoE Pass-Through  (Patent Pending)
[Description]

Dualcomm's patent pending 5-Port 10/100/1000Mbps Gigabit Desktop Switch (DCGS-2005) offers several unique features that
differentiate it from other vendor's Gigabit desktop switches on the market.

  • "Power over Ethernet" Inline Power Pass-Through

    DCGS-2005 implements a set of ports for "Power over Ethernet" (PoE) inline power pass-through, which provides a low
    cost solution to "expand" a PoE uplink port into four downstream ports, one of which is capable of receiving the inline
    power from the uplink cable to power a connected PD (e.g. an PoE enabled IP phone).

    The "PoE pass-through" 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.

  • Port-Mirroring

    DCGS-2005 offers a unique and low cost solution for any network applications where port-mirroring is required. Port-
    mirroring used to be a feature in much more expensive managed switches requiring a series of software configurations,
    but DCGS-2005 makes it plug and play without any software manipulations at a much lower price point.

  • USB Powered

    DCGS-2005 is designed to be conveniently power-able by any USB port of a computer so that an otherwise heavy and
    bulky AC/DC power adapter becomes not necessary!
