5.7.2 DCN Interfaces
MINI-LINK TN R4 provides an IP based DCN for transport of its O&M data.
Each NE has an IP router for handling of the DCN traffic. A number of different
alternatives to connect and transport DCN traffic are supported. This diversity of
DCN interfaces provides the operator with a variety of options when deploying
a DCN. Figure 86 on page 115 illustrates the different options, including ways
of connecting to the equipment for DCN configuration.

The internal IP traffic is transported on nx64 kbit/s channels on the TDM bus in
the backplane. The internal channels are automatically established at power up.
