Configuring Unchannelized DS3 Cards (MAX TNT, DSLTNT)

Introduction to unchannelized DS3

The unchannelized DS3 slot card (UDS3), supported on the MAX TNT and the DSLTNT, is a
44.736Mbps communications circuit that can be used to concentrate incoming traffic on the
unit and direct it to a Frame Relay switch. Figure9-1 shows an example of an unchannelized
DS3 slot card application.
