PVC (Private Virtual Circuit) Settings

Option Description

VPI: (Virtual Path Identier) If instructed

to change this, type in the VPI value

for the initial connection (using PVC 0).

VCI: (Virtual Channel Identier) If instructed

for the initial connection (using PVC 0).

Your modem can support up to 8 PVCs.

For example, you could have one PVC

(8/35) for your Internet trafc, and

another PVC (9/35) for your VoIP trafc.

Contact your ISP for further details.

QoS: Default is UBR (Unspecied Bit Rate).

Change this setting if your ISP instructs

you to do so. The other settings are CBR

(Constant Bit Rate) and VBR (Variable

Bit Rate).

PCR: Divide the DSL line rate (bps) by 424

(the size of an ATM cell) to nd 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 Rate. Represents the

maximum number of cells accepted

over a period of time. When the cell rate

exceeds the MBS cells can be dropped.

CDVT: Cell Delay Variation Tolerance. If your

PVC is a CBR service you need to set

the PCR and CDVT parameters. Ask your

ISP what the best settings are for these

on their network.

Auto PVC: If enabled your modem will automatical-

ly detect your PVC (VPI/VCI) settings.
