4.2 Single DU Connections in GSM
This section describes how to connect the DU to the RUGs in a configurationwith a single DU. An example of connections are shown in Figure 28 and singleDU connections are described in Table 20.
Note: Only connect the DU to positions that are actually occupied by an RUand leave any other connections vacant. For example, do not connectthe RI F connector in the DU if there is no RU in position 6.

4.6 Multi Node DU Connections
This section describes how to connect the DUs in a multi node configuration.A multi node configuration can span across several subracks which mustbe connected with long cables between DU-RU and RU-RU. Use the sameCPRI and Coax cables as noted in the single node sections. An example ofconnections for multi node are shown in Figure 34.
