DESCRIPTION
Press [SPACE BAR] to select the method of multiplexing used by your ISP.
Choices are VC-based or LLC-based.
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a
virtual circuit. The valid range for the VPI is 0 to 255. Enter the VPI
assigned to you.
The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for local
management of ATM traffic). Enter the VCI assigned to you.
voice or data traffic. Select UBR (Unspecified Bit Rate) for applications
that are non-time sensitive, such as e-mail. Select VBR (Variable Bit
Rate) for bursty traffic and bandwidth sharing with other applications.
Divide the DSL line rate (bps) by 424 (the size of an ATM cell) to find the
Peak Cell Rate (PCR). This is the maximum rate at which the sender can
send cells. Type the PCR here.
The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that
can be transmitted. Type the SCR, which must be less than the PCR. Note
that system default is 0 cells/sec.
Maximum Burst Size (MBS) refers to the maximum number of cells that
can be sent at the peak rate. Type the MBS, which is less than 65535.
(PPPoE and PPPoA only) Enter the login name given to you by your ISP.
(PPPoE and PPPoA only) Type your password again for confirmation.
(ENET ENCAP only) Enter the gateway IP address provided by your ISP.
(PPPoE and PPPoA only) Specify an idle time-out. The default setting is 0,
which means the Internet session will not timeout.
If your ISP did not assign you a fixed IP address, press [SPACE BAR] and
then [ENTER] to select Dynamic, otherwise select Static and enter the
IP address and subnet mask in the following fields.
This field is enabled if the IP Address Assignment is Static. Enter the
(fixed) IP address assigned to you by your ISP (static IP address
assignment is selected in the previous field).
