Introduction
About the 5600 Series DSL Router
The SpeedStream TM 5600 Series Ethernet to ADSL router provides
ATM-based network access for home users, telecommuters, or remote
offices and are equipped with one Ethernet port and one Asymmetric
Digital Subscriber Line (ADSL) port. These internet sharing devices use
Discrete Multitone (DMT) technology to set data transmit rates. When the
unit is first powered on, it will “train” the line to get the best data
transmission rate.
The 5600 Series internet sharing device can be used as either a router or a
bridge. It is configured to operate as a router when it is first installed. To
use it as a bridge, you must log into the router and change the mode to
bridge mode.
Router Mode (factory default mode):
• Provides IP routing between a Local Area Network (LAN) and the Wide
Area Network (WAN).
• Can be configured to use
• PPP (factory default)
• RFC 1483 routed encapsulation
• RFC 1483 bridged encapsulation
Bridge Mode:
• Provides high-speed connectivity from an Ethernet LAN to the WAN
over the ADSL connection
• Uses RFC 1483 bridged encapsulation over ATM
Routing vs. Bridging
What is the difference between routing and bridging?
• Bridges determine where to send data packets between local area
network (LAN) segments based on the MAC address of the sending and
receiving computers or devices (nodes) on the network. The MAC
address is a unique identifier that is programmed into the network
