The high-capacity protocol control information (PCI) adapter card for DTM can be used to build highly efficient service networks for content server providers. Network and service providers searching for new business opportunities can use DTM to build high-capacity marketplaces for content providers with high-capacity and reliability requirements such as Web hotels, MPEG2 providers, and public databases.

Benefits of using DTM as a content-server network include the following:

• DTM allows scalability in capacity from 512 kbps to transmission speeds close to the utilization of the fiber.
• DTM can use the fibers as shared medium, which allows for redundant topologies that are easy to expand.
• DTM provides isolated synchronous channels, which ensures service quality.
• DTM channels are unidirectional and resource usage is optimized for the traffic characteristics of content servers (asymmetric traffic load).
• Billing per usage of resources is possible.
