VCI (Virtual Channel Identifier) — Adds a VCI entry to the table.
◆
(Range: 32-65535; Default: 35)
QoS — Selects packet level Quality of Service (QoS) for the connection.
◆
Options are:
UBR (Unspecified Bitrate): Configures a PVC with a Peak Cell Rate
■
indicating the maximum number of ATM cells that can be sent in a
burst.
CBR (Constant Bitrate): Configures a PVC at a constant bit rate.
■
This option may be required for connections that depend on precise
clocking to ensure undistorted delivery.
nrt-VBR (non-realtime Variable Bitrate): Configures a PVC at a
■
non-realtime variable bit rate. This option may be used for
applications not sensitive to changes in available bandwidth, such
as data.
rt-VBR (realtime Variable Bitrate): Configures a PVC at a real-time
■
variable bit rate. This option may be used for applications that have
a lot of variance in required bandwidth, such as voice.
PCR (Peak Cell Rate) — Configures the maximum allowable rate at
◆
which cells can be transported along a connection in the ATM network.
The PCR is the determining factor in how often cells are sent in relation
to time in an effort to minimize jitter.
◆ CDVT (Cell Delay Variation Tolerance) — Configures the maximum
amount of jitter permissable.
SCR (Sustainable Cell Rate) — Configures the average allowable, long-
◆
term cell transfer rate on a specific connection.
MBS (Maximum Burst Size) — Configures the maximum allowable
◆
burst size of cells that can be transmitted contiguously on a particular
connection.
Current ATM VC Table — The Current ATM VC Table lists the current
◆
ATM settings configured on your ADSL Router. By selecting the
connection using the radio button associated with it you can edit the
connection parameters.
