Line Card Splitter Deployment
Figure 5
In DMT/ISDN line card deployments, you use CPE and CO splitters to separate the two signals.
DMT/ISDN splitters permit both telephone voice and data signals to be transported as data from and to
the CPE. You can install as many as 30 ATUC-4DMT-ISDN line cards in a single splitter-configured
Cisco 6260 DSLAM.
The network configuration consists of the two following principal hardware groups:
•
The CPE facility
•
The CO facility
