DESCRIPTION
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.
Select CBR (Continuous Bit Rate) to specify fixed (always-on) bandwidth
for 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.
Cell rate configuration often helps eliminate traffic congestion that slows
transmission of real time data such as audio and video connections.
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.
(PPPoA and PPPoE encapsulation only)
This field is only available when PPPoE encapsulation is selected. Type
the PPPoE service name provided to you. PPPoE uses a service name to
identify and reach the PPPoE server.
This field is only available when PPPoE encapsulation is selected.
Select the checkbox to enable PPPoE pass through. In addition to the
Prestige's built-in PPPoE client, you can enable PPPoE pass through to
allow up to ten hosts on the LAN to use PPPoE client software on their
computers to connect to the ISP via the Prestige. Each host can have a
separate account and a public WAN IP address. PPPoE pass through is
an alternative to NAT for application where NAT is not appropriate.Disable
PPPoE pass through if you do not need to allow hosts on the LAN to use
PPPoE client software on their computers to connect to the ISP.
Enter the user name exactly as your ISP assigned. If assigned a name in
the form user@domain where domain identifies a service name, then
enter both components exactly as given.
Enter the password associated with the user name above.
This option is available if you select Routing in the Mode field.
A static IP address is a fixed IP that your ISP gives you. A dynamic IP
address is not fixed; the ISP assigns you a different one each time you
connect to the Internet. The Single User Account feature can be used with
either a dynamic or static IP address.
Select Obtain an IP Address Automatically if you have a dynamic IP
address; otherwise select Static IP Address and type your ISP assigned
IP address in the IP Address field below.
The schedule rule(s) in SMT menu 26 have priority over your Connection
settings.
