MODEL- 5651-00-00AF       VENDOR- ZOOM TELEPHONICS
    
FEATURES- X4 Ethernet/USB ADSL 2/2+ Modem
       External ADSL Modem/Gateway/Router/Firewall with Ethernet and USB 
        Interfaces.
       The Zoom Model 5651 ADSL X4 is a full-rate ADSL 2/2+ modem and a 
        powerful gateway/router/firewall in a single affordable product.
       The Model 5651 X4 delivers up to 24 Mbps data speeds over existing 
        telephone wires and is suitable for use in homes or small offices. 
        The Model 5651 is compatible with older ADSL protocols as well as 
        the new ADSL 2/2+ standards for higher data speeds and extended 
        distances at which high data rates can be delivered. The Ethernet
        interface on the X4 provides connection to a computer running most 
        operating systems, including Windows 95, 98, 98SE, 2000, XP and Me 
        as well as Linux, Unix and Mac Operating system. The X4 can also be 
        plugged into a hub or wireless access point to provide concurrent 
        Internet access for up to 253 networked computers. The USB port
        supports connection to a Windows computer.
       Security features include Network Address Translation (NAT), and 
        Stateful Packet Inspection (SPI). The NAT firewall hides computers 
        on the local area network from uninvited access through the 
        Internet. SPI assesses the protocol and packet addresses being 
        received to determine if the information should be passed through 
        the firewall to the connected computers. SPI and NAT protect 
        against Internet worms and Denial of Service attacks, some of the 
        most publicized forms of malicious intrusion from the Internet.
       Setup is easy using any authorized local or remote computers Web  
        browser and the intuitive graphical user interface. An auto 
        configuration option automatically establishes the protocol and 
        encapsulation used by the ADSL service. Simple Network Management
        Protocol (SNMP) is supported for remote maintenance by network 
        administrators.
       Zoom ADSL gateways are backed by a two year warranty and over 27 
        years of experience in the design and support of communication 
        products.
    Includes Ethernet/USB Modem, Ethernet cable, USB cable, Phone cable,
      CD-ROM, User manual, Power adapter, Filters and phone adapters.
