Your ADSL line VPI and VCI setting
Your ADSL encapsulation type or multiplexing (Either LLC or VC. Check your ISP for detail)
Your ADSL Training Mode or Handshaking Mode (default is MMODE)
For PPPoA or PPPoE users, you also need these values from your ISP:
Your account Username
Your account Password
For RFC 1483 users, you may need these values from your ISP:
Your ADSL fixed Internet IP address
Your Subnet Mask
Your Default Gateway address
Your primary DNS IP address
Since multiple users can use the TDM-C504 ADSL2/2+ Modem Router, the TDM-C504 ADSL2/2+ Modem
Router can simultaneously support multiple connection types; hence, you must set up different profiles for
each connection. The TDM-C504 ADSL2/2+ Modem Router supports the following protocols:
PPPoE
PPPoA
1483 Bridged
1483 MER
1483 Routed
The WAN setup configuration page enable the user to create, save, delete and select connection profiles as
required. (In many cases, only one connection profile will be required and only one connection profile will be
used at one time).
Bridge Mode
ADSL router is bridge mode enabled by factory default. There is a 1483-bridged mode PVC 5/35 in system.
1483 Bridged: When 1483 Bridged mode is selected, the following screen will pop-up. A Bridged connection
basically disables the routing, firewall and NAT features of the 4 Ports ADSL2/2+ Router. In a 1483 Bridged
connection, the 4 Ports ADSL2/2+ Router acts as a modem or hub, and just transmits packets between the
WAN interface and the LAN interface. A 1483 Bridged connection assumes that another device is providing
the routing functionality that is now disabled in the 4 Ports ADSL2/2+ Router.
LLC and VC-Mux are two different methods of encapsulating the PPP packet. Contact your ISP to make
sure which encapsulation is being supported.
Channel:
VPI: Virtual Path Identifier is a virtual path used for cell routing that is identified by an 8-bit
field in the ATM cell header. The VPI field specifies this 8-bit identifier for routing.
VCI: A Virtual Channel Identifier is a virtual channel that is identified by a unique numerical
tag that is defined by a 16-bit field in the ATM cell header. The purpose of the virtual
channel is to identify where the cell should travel. The VCI field specifies this 16-bit
numerical tag that determines the destination.
Encapsulation: There are 2 Encapsulation type:
