Abstract
At a base repeater site which employs ethernet connectivity to a site controller, it is imperative that the site controller is capable of associating an ethernet address of a particular repeater with its physical loca- tion in the site racking network. This is required for station programming, to aid in Frequency planning, and in fault isolation. The described circuit network provides a means to automatically associate the base stations ethernet address with its location in the site antenna network. While the same result may be obtained manually, it would require much more time, increased risk for error, and cost. Furthermore, the described circuit network is capable of performing this association in a non-intrusive manner while the system is running, which is required for system growth or modifications.

The base station determines it's location within the site racking and antenna network by means of the described network connected to the RF distri- bution system power monitoring devices whose out- puts are routed back to the repeaters where the data is Iirrther analyzed. These output signals are nor- mally simply analog voltages representative of the forward and reflected power at the antenna port. The input path to the repeater is from the power moni- tor to an analog to digital converter located internal to the repeater. These converted signals are "read" by the control module to determine ifan alarm con- dition exists (e.g. high VSWR).
The described network adds a se...
