ATM VC
Virtual Circuit: VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) define a
virtual circuit.
VPI: The valid range for the VPI is 0 to 255. Enter the VPI assigned to you. This field may
already be configured.
VCI: The valid range for the VCI is 32 to 65535. Enter the VCI assigned to you. This field
may already be configured.
ATM QoS: Select CBR to specify fixed (always-on) bandwidth for voice or data traffic.
Select UBR for applications that are non-time sensitive, such as e-mail. Select VBR for burst
traffic and bandwidth sharing with other applications.
PCR: 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.
SCR: The Sustain Cell Rate (SCR) sets the average cell rate (long-term) that can be
transmitted.
MBS: 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
Encapsulation:
ISP: Select the encapsulation type your ISP uses from the Encapsulation list.
Choices vary depending on what you select in the Mode field.
If you select Bridge in the Mode field, select 1483 Bridged IP.
If you select Routing in the Mode field, select PPPoA, 1483 Bridged IP, 1483 Router IP or
PPPoE.
PPPoE/PPPoA
User Name: Enter the user name exactly as your ISP assigned.
Password: Enter the password associated with the user name above.
Encapsulation: select Bridge in the Mode field, select either PPPoA or RFC 1483.

Multiplex: Select the method of multiplexing used by your ISP. Choices are VC or LLC.
Connection: The schedule rule(s) have priority over your Connection settings.
Always on: Select Always on Connection when you want your connection up all the time.
Connect on Demand: Select Connect on Demand when you don't want the connection up
all the time and specify an idle time-out in the Max Idle Timeout field
Get IP Address: Choose Static or Dynamic
Static IP Address: Enter the IP address of ADSL Router in dotted decimal notation, for
example, 192.168.1.254 (factory default).
IP Subnet Mask: The default is 255.0.0.0. User can change it to other such as
25
