I am a sub-partner/customer to an aggregator that is already connected to DCS. Do I need to do something?

In this case we will receive your data via the roaming connection already in place with the aggregator. Shall it meet DCS quality requirements and the offered commercial conditions are acceptable; your network will be configured for display on the front-ends managed by DCS. Thus, the process is shorter and benefits from the existing connection with the respective aggregator.
