Single Points of Failure and Redundancy

With the onset of Narrowbanding and Rebanding tasks before many public safety radio systems operators, it does present the opportunity to take a hard look at your legacy radio system/s that have been in use for many years and do a risk analysis as to single points of failure as well as look at redundant systems and how effective they are.

We often find visiting public safety answering points (PSAP’s) that good planning went into their respective voice, data and telephone systems however, the backup modes are either infrequently or never tested.

In trunked systems the main central controller should be backed up as it is the key to the operation of the networked system.

When we review routing of telephone circuits, such as commonly used T1’s used to link remote sites, we find in many cases that when there are multiple T1 circuits linking a remote site that the routing by the local exchange carrier is from the same central office or multiple central offices. If there is a failure of a circuit card at the central office, it obviously will render that one site out of service.

These are examples of some of the services we provide our customers.
