Abstract

The next generation trunking subscriber controller needs to solve the problem of incorporating a relatively large memory space at a moderate cost and in a small area. One way of achieving these goals is to use a IM BIT (128K x 8) static RAM to incorporate the product software and features, as well as the customer informa- tion. To retain this data at all times, a battery back-up circuit is used. However, because a failure in the battery back-up circuit could occur, destroying the firmware and customer information, an improved method for pro- gramming the two-way radios over the airways was devised.
