Various arrangements of a connection system are presented. The system can include radio cable ports. Each radio cable port may be communicatively connected with a different antenna of an antenna system. Each radio cable port may be keyed different such that only a particular keyed cable assembly can be mated with the radio cable port. The system can also include antenna cable ports. Each antenna cable port can be configured to be communicatively connected with a different radio of a radio system. Each antenna cable port may be keyed different such that only a particular keyed cable assembly can be mated with the antenna cable port. Each radio cable port is keyed in a same pattern as an antenna cable port with which the radio cable port is intended to be communicatively connected.

Method for topology determination in a mobile communications site, wherein the mobile communications site has n nodes each having m ports. In determining (S.sub.1), the number of existing nodes is determined. In designating, one of these nodes is designated as the master node and the others as slave nodes. In selecting, a slave node is selected as a test slave node and the communication of the other slave nodes is prevented. In testing, a test is performed to determine via which ports of the master node and via which ports of the test slave node a communication is possible. Thereafter, selecting and testing are repeated for the other slave nodes, wherein in the method step selecting, a different slave node is selected as the test slave node in each case. In the method step generating, a connection topology is then generated for the master node.
