Sharing High-Speed Internet Access
ZyXEL P-2302R series is a broadband sharing gateway that allows the PCs on your home LAN to share resources and files with online peers, and to access the Internet through your existing DSL/Cable Router.
Enabling VoIP Phone Services
The two built-in standard phone jacks on the P-2302R series allows you to enjoy VoIP conversations while surfing the Internet. Since phone numbers given by service providers can be assigned to either each phone port individually or to two phone ports at the same time, the P-2302R series is equivalent to two phone lines, free of extra charge. This offers unprecedented flexibility and freedom for you to talk non-stop with high-speed broadband connection.

Easy to Install and Manage
Thanks to ZyXEL’s exclusive Auto-provisioning mechanism, allowing the service provider to manage and configure the unit remotely to reduce the complexity and cost of deployment of CPE to end-users. To extend your non-stop telephone or broadband reach, ZyXEL P-2302R series is the most affordable solution for you to take full advantage of your home or SOHO network.

Effective Network Bandwidth Management
The P-2302R series enables network administrators to allocate network resources while guaranteeing Quality of Service (QoS). Network Bandwidth Management increases productivity and efficiency by tailoring a system to specific demands such as time-sensitive VoIP and multimedia applications.

Robust, State-of-the-Art Firewall Security
The ICSA certified ZyNOS operating system ensures state-of-the-art Firewall performance and robust security from the P-2302R series.
