Common use of Fault Tolerance Clause in Contracts

Fault Tolerance. Following is a list of fault tolerant capabilities of the System. It is important to keep in mind that although this discussion treats a board as a single point failure, typically this is not accurate. Many of the boards contain identical functional blocks such as T1/E1 interfaces or voice transcoding circuits. In such instances, a board may be capable of functioning with some but not all of its capability. In other instances, performance of a board may degrade without an apparent failure. Critical circuitry is monitored as practical, and equipment alarms are generated so that a board may be replaced before an interruption of service occurs.
