Chapter 6 Broadband Table 8 Broadband: Add/Edit: Bridge Mode LABEL DESCRIPTION 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.This field is not available when you select UBR Without PCR. 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 This field is available only when you select Non Realtime VBR or Realtime VBR. Maximum Burst Size (MBS) refers to the maximum number of cells that can be sent at the peak rate.

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.This field is not available when you
select
UBR Without PCR
.
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.
This field is available only when you select
Non Realtime VBR
or
Realtime VBR
.
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.
This field is available only when you select
Non Realtime VBR
or
Realtime VBR
.
VLAN (These fields appear when the
Type
is set to
VDSL
or
Ethernet
)
Active
Select this option to add the VLAN tag (specified below) to the outgoing
traffic through this connection.
802.1P
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag
into a MAC-layer frame that contains bits to define class of service.
Select the IEEE 802.1p priority level (from 0 to 7) to add to traffic
through this connection. The greater the number, the higher the
priority level.
802.1Q
Type the VLAN ID number (from 1 to 4094) for traffic through this
connection.
