Chapter 6 WAN Setup Table 23 Network > WAN > More Connections: Edit: Advanced Setup (continued) LABEL DESCRIPTION ATM QoS Type 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-nRT (Variable Bit Rate-non Real Time) or VBR-RT (Variable Bit Rate-Real Time) for bursty traffic and bandwidth sharing with other applications. Peak Cell Rate 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. Sustain Cell Rate 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 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. MTU MTU 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. Packet Filter Incoming Filter Sets Protocol Filter For PPPoA and RFC, the MTU is 65535. Select the protocol filter(s) to control incoming traffic. You may choose up to 4 sets of filters. Generic Filter You can configure packet filters in the Packet Filter screen. See Chapter 12 on page 219 for more details.

ATM QoS Type
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-nRT
(Variable Bit Rate-non Real Time) or
VBR-RT
(Variable Bit Rate-Real Time) for bursty traffic and bandwidth
sharing with other applications.
Peak Cell Rate
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.
Sustain Cell Rate
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
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.
MTU
MTU
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, the MTU is 65535.
