DSL-500 ADSL Router User's Guide Print this page for your records VPI and VCI Settings Your Telephone Company will provide two numbers, a Virtual Path Identifier (VPI) and a Virtual Channel Identifier (VCI). You will need to enter these two numbers during the configuration of the Router. In order to ensure high quality of service and maximum performance, ADSL technology employs Asynchronous Transfer Mode (ATM) networks (via the DSLAM). ATM networks use Permanent Virtual Circuits (PVCs) to establish end-to-end software defined logical connections. The VPI and VCI are contained in the ATM cell header. These numbers help manage ATM network connections and identify logical links formed by PVCs. For convenient reference, you may want to record the VPI and VCI numbers here, as well as the MAC (Physical) Address of the Router. VPI, VCI and MAC Address VPI VCI MAC Address Global IP Address Your ISP will supply you with a unique global IP address that you must use if you choose to connect to the ISPs network using the RFC 1483 defined "Bridged Ethernet" encapsulation method. If you use PPPoA to define the connection to your ISP you do not need to assign a global IP address. This is explained further in chapter 3 in the discussion of Connection Method. Global IP Address Default Gateway IP Address Some ISPs require the use of a default gateway router. If this is necessary, your telephone company or ISP will provide the IP address of a device to be used for this purpose. Use the space provided below to record the IP address of the ISPs default gateway router. Default Gateway IP Address Print this page for your records v
