Lessons Learned – Telephone System Failure
Year: 1993
Abstract: Description of Driving Event:
A new telephone system went into a total failure condition and remained that way for 10 1/2 hours. This failure resulted in the entire lab being without telephone service, external calls, internal calls and VMX service.
The investigative team concluded that a switch failure caused the system breakdown. A contingency plan containing emergency procedures for a telephone system collapse was created.
