Configuring VDSL2 Bonding and Single-Wire Pair

Very-high-bit-rate digital subscriber line 2 (VDSL2) bonding combines two copper wire pairs to increase the capacity or extend the copper network's reach. For a customer, this means enhanced data rate and operation on longer loops. A single-wire pair enables you to configure profile 8a through 17a and ADSL on line 0, and profile 8a through 30a on line 1. VDSL2 bonding and single-wire pair are supported on C897VAB-K9 series router.

This chapter contains the following sections:

Restrictions

The following restrictions are applicable to VDSL2 bonding on the Cisco 800 Series Routers:

  • VDSL2 bonding is supported only on the C897VAB-K9 Series Router.

  • Even though C897VAB-K9 is a bonding SKU, bonding is not the default configuration. The ADSL mode and VDSL single-wire mode are supported in the default configuration. You should enable bonding using the line-mode bonding command.
  • The no line-mode bonding and default line-mode bonding commands change the configuration to 'single-wire' on Line 0, which is the default configuration.
  • The line-mode configuration is removed from the router whenever you change the operating mode. You have to run the command again in the new operating mode to configure bonding.

Configuring Bonding in Auto Mode

You can configure bonding either in auto mode or VDSL2. The default configuration is auto.

Perform the following tasks to configure bonding in auto mode:

          Configuration Examples

          The following example shows how to enable bonding in auto mode:

          router# configure terminal
          router(config)# controller vdsl 0
          router(config)# operating mode auto
          router(config-controller)# line-mode bonding
          router(config-controller)# exit

          The following example shows how to enable VDSL2 bonding:

          router# configure terminal
          router(config)# controller vdsl 0
          router(config)# operating mode vdsl2
          router(config-controller)# line-mode bonding
          router(config-controller)# exit

          The following example shows how to remove bonding:

          router# configure terminal
          router(config)# controller vdsl 0
          router(config)# no operating mode 
          router(config-controller)# no line-mode bonding
          router(config-controller)# exit

          The following example shows how to enable profile 8a through 17a on line 0:

          router# configure terminal
          router(config)# controller vdsl 0
          router(config-controller)# line-mode single-wire line 0
          router(config-controller)# exit

          The following example shows how to enable profile 30a on line 1:

          router# configure terminal
          router(config)# controller vdsl 0
          router(config-controller)# line-mode single-wire line 1 profile 30a
          router(config-controller)# exit

          The following example shows how to remove profile 30a from line 1:

          router# configure terminal
          router(config)# controller vdsl 0
          router(config-controller)# no line-mode single-wire line 1
          router(config-controller)# exit
