Methodology and corresponding apparatus ensure the integrity of utility metering data during power outages while providing improved memory integrity. An initial step includes determining and storing an energy top value that is representative of metered energy, and also includes establishing an update pattern. Accumulated energy is then monitored until a predetermined energy threshold is crossed, at which point a selected state in the update pattern is stored into one of a plurality of energy increment cells. Such stored value can be validated at some point after the data read. The steps of monitoring accumulated energy and storing a selected value / state of the update pattern into additional energy increment cells continue until each of the plurality of energy increment cells is updated with a new value. Upon completion, the energy top value is updated with a new energy total and the process of cycling through each energy increment cell is repeated.

A communications system connects one or more BTS hotels with several remote access nodes on a transmission ring. Each operator has one or more separate optical wavelengths. Signal flow around the ring can either be uni-directional or bi-directional. Each optical wavelength (or wavelength pair) contains the wireless signal traffic for all remote nodes in the ring for the operator using that particular wavelength in digital form. At each node, the incoming signals are electrically demultiplexed and appropriate signals for that node are extracted for conversion to RF. These signals are copied rather than cut so that they are also available at following remote antenna nodes, thereby enabling simulcast operation.
