6.3 The More Connections Screen

The Device allows you to configure more than one Internet access connection. To configure
additional Internet access connections click Network > WAN > More Connections. The screen
differs by the encapsulation you select. When you use the WAN > Internet Access Setup screen
to set up Internet access, you are configuring the first WAN connection.

DESCRIPTION
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 rtVBR (real-time Variable Bit Rate) type for
applications with bursty connections that require closely controlled delay and delay
variation. Select nrtVBR (non real-time Variable Bit Rate) type for connections that
do not require closely controlled delay and delay variation.
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.
The Maximum Transmission Unit (MTU) defines the size of the largest packet allowed
on an interface or connection. Enter the MTU in this field.
For ENET ENCAP, the MTU value is 1500.
For PPPoE, the MTU value is 1492.
For PPPoA and RFC 1483, the MTU is 100-1500.
