“Enable”
.
Type:
Connection Type :
CLIP
.
PVC Settings:
VPI:
Virtual Path Identifier is a virtual path used for cell routing that is identified by an eight bit field
in the ATM cell header. The VPI field specifies this eight bit identifier for routing.
VCI:
A Virtual Channel Identifier is a virtual channel that is identified by a unique numerical tag that
is defined by a 16-bit field in the ATM cell header. The purpose of the virtual channel is to identify
where the cell should travel. The VCI field specifies this 16 bit numerical tag that determines the
destination.
QoS:
Select the
Quality of Service
(QoS) type. If in doubt leave as default.
PCR:
Peak Cell Rate. This is an ATM (Asynchronous Transfer Mode) term to describe the rate
cells per second that the source device may never exceed. Available only when VBR QoS is
chosen.
SCR:
Security Cell Rate. This is an ATM (Asynchronous Transfer Mode) term to describe the
security cell transmitted per second.
MBS:
Maximum Burst Size. A term used in ATM (Asynchronous Transfer Mode) to specify the
maximum number of cells which can be transmitted at the contracted PCR (Peak Cell Rate).
Available only when VBR QoS is chosen.
CDVT:
Cell Delay Variation Time. The Cell Delay Variation is a term used in ATM (Asynchronous
Transfer Mode) to describe the time difference that is acceptable between cells being presented at
the receiving host. Available only when VBR QoS is chosen.
Auto PVC:
Click to enable Auto PVC features. Auto PVC allows detection of virtual channels via
the built-in mechanism for communicating ATM Layer information from DSLAM to the 4 Ports 11g
Wireless ADSL2/2+ Router.
