m multiple PSAP's, all of which
are receiving NO ALI, there is a problem with the Node or Node to Host
circuits or the Host computer itself. Before referring the trouble the
SSC/MAC should call the MMOC to inquire if the Node or Host is in
trouble.

Alarm conditions on the ANI controller digital display at the PSAP are
to be reported by the PSAP's. These alarms can indicate various
trouble conditions so the SSC/MAC should ask the PSAP if any portion of
the E911 system is not functioning properly.

The SSC/MAC should verify with the PSAP attendant that the equipment's
primary function is answering E911 calls. If it is, the SSC/MAC should
request a dispatch SSIM/I&M. If the equipment is not primarily used
for E911, then the SSC/MAC should advise PSAP to contact their CPE
vendor.

Note: These troubles can be quite confusing when the PSAP has vendor
equipment mixed in with equipment that the BOC maintains. The
Marketing representative should provide the SSC/MAC information
concerning any unusual or exception items where the PSAP should contact
their vendor. This information should be included in the PSAP profile
sheets.

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 wi
