When a PVC has a token available, it can transmit cells at the rate of PCR. After a cell is
transmitted, the PVC loses the token it has accumulated.
In the case of multiple PVCs, CBR specified PVCs will have higher priority than
PVCs with UBR. For example, the CBR PVCs will take their bandwidth and the re-
maining
bandwidth will be split among the UBR PVCs. In the case of total PVC CBR
bandwidth exceeding ADSL upstream, the total upstream bandwidth will be shared
proportionally to the bandwidth allocated for each CBR PVC.
Peak Cell Rate:
This value specifies the maximum, and in some cases guaranteed, cell
rate for CBR and VBR-nrt. Peak Cell Rates are typically measured in Cells/Second,
however, the user entered value is in kbps and is then converted by the firmware.
Range: 0-32767
Default: 0
Sustainable Cell Rate:
It is the sustained rate at which a PVC enabled with VBR-nrt can
transmit ATM cells. Sustainable Cell Rate (SCR) can be considered as the true reserved
bandwidth for a PVC.
Range: 0-32767
Default: 0
Max Burst Size:
It is the number of cells a PVC enabled with VBR-nrt can transmit con-
tinuously at peak cell rate (PCR).
Range: 0-32767
Default: 0
5.2.2 DHCP Client
DHCP Client:
It is to enable or disable (default) the Router WAN as a DHCP client,
where the ISP would be the DHCP server. DHCP Client is generally used in the following
encapsulations: 1483 Bridged IP LLC, 1483 Routed IP LLC, 1483 Bridged IP VC-MUX,
1483 Routed IP VC-Mux, and Classical IP over ATM. This option is for non-static (dy-
namic) IP addresses.
Host Name:
When DHCP Client is Enabled, copy the ISP recognized Host Name here.
The Host Name can be up to 19 characters.
