Configuring DS3-ATM Cards
Introduction DS3-ATM
The DS3-ATM cards (DS3-ATM and DS3-ATM2) support one 44.736Mbps interface for
connecting to one ATM switch. At a minimum, you must enable the line and specify a nailed
group. TAOS units use the nailed group to direct traffic to the interface.
Note: The DS3-ATM card is supported on the MAX TNT and DSLTNT platforms only. The
DS3-ATM2 card is supported on the APX 8000, MAX TNT, and DSLTNT platforms. Both
cards use the same configuration profiles, but at the time of this writing, the DS3-ATM2 card
does not support ATM-Frame Relay circuit configurations. Maximum performance with the
DS3-ATM2 card is achieved using RFC 1483 ATM-AAL5-CPCS-PDU encapsulation.
This chapter refers to both the DS3-ATM and DS3-ATM2 cards as DS3-ATM cards.
An example use of a DS3-ATM interface is shown in Figure 14-1.

Overview of DS3-ATM settings
A TAOS unit creates a DS3-ATM profile for each DS3-ATM interface detected in the system.
Following are the relevant parameters, shown with default values:
[in DS3-ATM/{ any-shelf any-slot 0 }]
name = ""
physical-address* = { any-shelf any-slot 0 }
enabled = no
