This Redundant Link provides a more reliable communication link for the redundant RNG config- uration used in the DataTAC 5000 wireless data net- work. With the current design, a network problem in the DataTAC 5000 could cause the RNG pair to synchronize improperly making the whole network unstable. One network problem is when a 1ObaseT repeater fails causing the RNGs to switchover. As soon as the failed 1ObaseT repeater recovers, the RNGs resume communication but fail to synchro- nize properly resulting in another switchover. If the 1ObaseT repeater fails intermittently the RNGs would also switchover intermittently! Each RNG switchover causes a DataTAC network service inter- ruption, which is undesirable. Having the Redundant Link, this unnecessary RNG switchover can be prevented so the DataTAC network can be mom reliable.
