The ADSL X5 integrates an ADSL 2/2+ modem, a router, a NAT firewall, and a four-port 10/100 Ethernet switch into a single cost-effective product. The X5 is compatible with older ADSL protocols as well as the ADSL 2/2+ standards for download speeds of up to 24 Mbps and extended distances at which high data rates can be delivered. The Models 5754 is identical in all ways other than the four-color package design.
