6.7.2 DCN Interfaces
MINI-LINK TN R3 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 89 on page 115 illustrates the different options, including ways
of connecting to the equipment for DCN configuration.

All clocks, used for example for time stamping alarms and events, can be
synchronized with a Network Time Protocol (NTP) server.
File Transfer Protocol (FTP) is used as a file transfer mechanism for
software upgrade, and for backup and restore of system configuration.
Domain Name System (DNS) enables the use of host names.
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.
