LABEL DESCRIPTION
xDSL Port Setup Click xDSL Port Setup to go to the screen where you can configure DSL port
settings (see Section 13.5 on page 104 ).
PPVC Setup (STU-C mode only) Click PPVC Setup to open the PPVC Setup screen where
you can configure priority PVC settings for the DSL ports (see Section 13.9 on
page 113 ).
Port Use this drop-down list box to select a port for which you wish to view or
configure settings. This field is read-only once you click on a port number below.
Super Channel The IES-708-22A forwards frames belonging to VLAN groups that are not
assigned to specific channels to the super channel.
Enable the super channel option to have this channel forward frames belonging
to multiple VLAN groups (that are not assigned to other channels).
The super channel functions in the same way as the channel in a single channel
environment.
VPI Type the Virtual Path Identifier for a channel on this port.
VCI Type the Virtual Circuit Identifier for a channel on this port.
DS VC Profile Use the drop-down list box to select a VC profile to use for this channel’s
downstream traffic shaping.
US VC Profile Use the drop-down list box to select a VC profile to use for this channel’s
upstream traffic. The IES-708-22A does not perform upstream traffic policing if
you do not specify an upstream VC profile.
Note: Upstream traffic policing should be used in conjunction with
the ATM shaping feature on the subscriber’s device. If the
subscriber’s device does not apply the appropriate ATM
shaping, all upstream traffic will be discarded due to
upstream traffic policing.
