DS Carrier1

Mask0 represents tones 256~287

(256~511)

Mask1 represents tones 288~319

 

Mask2 represents tones 320~351

 

Mask3 represents tones 352~383

 

Mask4 represents tones 384~415

 

Mask5 represents tones 416~447

 

Mask6 represents tones 448~479

 

Mask7 represents tones 480~511

 

For example, use 0x00001000 in Mask1 to disable downstream carrier tone

 

307. Use 0x0000f000 in Mask1 to disable downstream carrier tones 304 to 307.

 

 

Apply

Click Apply to save your changes to the IES-612-51A’s volatile memory. The

 

IES-612-51A loses these changes if it is turned off or loses power, so use the

 

Config Save link on the navigation panel to save your changes to the non-

 

volatile memory when you are done configuring.

13.8 Virtual Channels

Defining virtual channels (also called Permanent Virtual Circuits or PVCs) allows you to set priorities for different services or subscribers. You can define up to eight channels on each DSL port and use them for different services or levels of service. You set the PVID that is assigned to untagged frames received on each channel. You also set an IEEE 802.1p priority for each of the PVIDs. In this way you can assign different priorities to different channels (and consequently the services that get carried on them or the subscribers that use them).

For example, you want to give high priority to voice service on one of the ADSL ports.

Use the Edit Static VLAN screen to configure a static VLAN on the IES-612-51A for voice on the port.

Use the ADSL Edit Port Channel Setup screen to:

•Configure a channel on the port for voice service.

•Set the channel to use the PVID of the static VLAN you configured.

•Assign the channel a high priority.

13.8.1Super Channel

The IES-612-51A forwards frames belonging to VLAN groups that are not assigned to specific channels to the super channel. Enable the super channel option to allow a 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. One port can have only one super channel.
