ATM SETTINGS
The ATM Settings page is used to configure the settings between your
ADSL Router and the remote ATM PVC switch, including connection mode
(single or multiple service over one connection), and packet level QoS.
The ATM Settings parameters form a Traffic Contract that informs the
network what type of traffic is to be transported and the performance
requirements of the traffic.

TABLE
The Current ATM VC Table lists the current ATM settings configured on your

with it you may edit the connection parameters which are listed below.
◆ Select — Clicking the radio button associated with the connection
makes the parameters editable.
◆ VPI (Virtual Path Identifier) — Adds a VPI entry to the table. (Range:
0-255; Default: 0)
◆ VCI (Virtual Channel Identifier) — Adds a VCI entry to the table.

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.
