Figure 4

Typical ATUC-4DMT-ISDN Direct-Connect Line Card Deployment

In direct connect deployments, Cisco ATUC-4DMT-ISDN line cards are a principal component of the
Cisco 6260 DSLAM normally located in a CO facility rack. You install from 1 to N (where N has any
value up to 30) line cards in a single Cisco 6260 DSLAM.

The network configuration consists of the following two principal hardware groups

•
