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.

Dynamic Host Configuration Protocol (DHCP) is used to allocate IP
addresses in the DCN. The NE has a DHCP relay agent for serving other
equipment on the site LAN.
