Pros / Cons

The 3Com IntelliJack Switch NJ220 is an in-the-wall, managed Ethernet switch that easily quadruples LAN infrastructure connections. Four switched ports and up to two pass-through ports connect a variety of devices via one wall outlet, making it more cost-effective than pulling additional wiring. This unique networking platform is ideal for hard-to-wire spaces such as asbestos-insulated walls, older buildings, dormitories, and modular cubicles.
