Select the method of encapsulation used by your ISP from the drop-down list box.
Choices vary depending on the mode you select in the Mode field.
If you select Bridge in the Mode field, select either PPPoA or RFC 1483.
If you select Routing in the Mode field, select PPPoA, RFC 1483, ENET ENCAP or
PPPoE.
Select the method of multiplexing used by your ISP from the drop-down list. Choices
are VC or LLC.
VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a virtual circuit.
Refer to the appendix for more information.
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.
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)
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.
The schedule rule(s) in the Prestige SMT menu 26 have priority over your
Connection settings.
Prestige will try to bring up the connection automatically if it is disconnected.
specify an idle time-out in the Max Idle Timeout field.
