Parameter	Specifies
Traffic-Shapers	Settings for shaping traffic on the interface. For details, see the
	APX 8000/MAX TNT/DSLTNT ATM Configuration Guide.
Cell-Payload-Scramble	Enable/disable scrambling and descrambling of the 48-byte ATM

	the far-end switch has disabled the corresponding functions.

Examples of DS3-ATM configurations

The following set of commands enables a DS3-ATM interface in slot 12 and assigns the nailed group number 111.

admin> read ds3-atm {1 12 1} DS3-ATM/{ shelf-1 12 1 } read

admin> set enabled = yes

admin> set line-config nailed-group = 111

admin> write

DS3-ATM/{ shelf-1 12 1 } written

Configuring redundant cards

When you are using two cards in a redundant configuration (as described in the hardware installation guide for your unit), both cards must use the same nailed group number to enable profiles to transparently use either card. After installing and cabling redundant cards, configure the primary card. For example:

admin> read ds3-atm {1 2 1} DS3-ATM/{ shelf-1 2 1 } read

admin> set enabled = yes

admin> set line-config nailed-group = 100

admin> write

DS3-ATM/{ shelf-1 2 1 } written

Next, configure the secondary card with the same nailed group. For example:

admin> read ds3-atm {1 3 1} DS3-ATM/{ shelf-1 3 1 } read

admin> set enabled = yes

admin> set line-config nailed-group = 100

admin> write

DS3-ATM/{ shelf-1 3 1 } written

If the primary card goes down, the TAOS unit switches over to the secondary card and reestablishes the link.
