The ADSL X5 integrates an ADSL 2/2+ modem, a router, an SPI firewall, and a four-port 10/100 Ethernet switch into a single cost-effective product. Four computers can plug directly into the X5. One or more of the Ethernet ports can be used to attach a switch, a hub, a wireless access point or any combination of those devices and provide high speed ADSL Internet access for up to 253 computers. The Model 5754 is compatible with older ADSL protocols as well as the newer ADSL 2/2+ standards for download speeds of up to 24 Mbps and extended distances at which high rates can be delivered. Advanced features of the 5754 include: Universal Plug and Play, a Stateful Packet Inspection (SPI) firewall, and an auto configuration option which automatically establishes protocol and encapsulation used by the ADSL service. The 5754 has Broadcom-based CPU/DSP chipset.
