ANI or ALI controller down: When the host computer sees the PSAP equipment down and it does not come back up, the MMOC will report the trouble to the SSC/MAC; the equipment is down at the PSAP, a dispatch will be required.
PSAP link (circuit) down: The MMOC will provide the SSC/MAC with the circuit ID that the Host computer indicates in trouble. Although each PSAP has two circuits, when either circuit is down the condition must be treated as an emergency since failure of the second circuit will cause the PSAP to be isolated.
Any problems that the MMOC identifies from the Node location to the Host computer will be handled directly with the appropriate MMOC(s)/CCNC.
Note: The customer will call only when a problem is apparent to the PSAP. When only one circuit is down to the PSAP, the customer may not be aware there is a trouble, even though there is one link down, notification should appear on the PSAP screen. Troubles called into the SSC/MAC from the MMOC or other company employee should not be closed out by calling the PSAP since it may result in the customer responding that they do not have a trouble. These reports can only be closed out by receiving information that the trouble was fixed and by checking with the company employee that reported the trouble. The MMOC personnel will be able to verify that the trouble has cleared by reviewing a printout from the host.
When the CRSAB receives a subscriber complaint (i.e., cannot dial 911) the RSA should obtain as much information as possible while the customer is on the line.
For example, what happened when the subscriber dialed 911? The report is automatically directed to the IMC for subscriber line testing. When no line trouble is found, the IMC will refer the trouble condition to the SSC/MAC. The SSC/MAC will contact Customer Services E911 Group and verify that the subscriber should be able to call 911 and obtain the ESN. The SSC/MAC will verify the ESN via 2SCCS. When both verifications match, the SSC/MAC will refer the report to the SCC responsible for the 911 tandem office for investigation and resolution. The MAC is responsible for tracking the trouble and informing the IMC when it is resolved.

The reader is forgiven if he or she was entirely unable to read this document. John Perry Barlow had a great deal of fun at its expense, in "Crime and Puzzlement:" "Bureaucrat-ese of surpassing opacity.... To read the whole thing straight through without entering coma requires either a machine or a human who has too much practice thinking like one. Anyone who can understand it fully and fluidly had altered his consciousness beyond the ability to ever again read Blake, Whitman, or Tolstoy.... the document contains little of interest to anyone who is not a student of advanced organizational sclerosis."
With the Document itself to hand, however, exactly as it was published (in its six-page edited form) in Phrack, the reader may be able to verify a few statements of fact about its nature. First, there is no software, no computer code, in the Document. It is not computer-programming language like FORTRAN or C++, it is English; all the sentences have nouns and verbs and punctuation. It does not explain how to break into the E911 system. It does not suggest ways to destroy or damage the E911 system.
