Maintenance Guidelines
~~~~~~~~~~~~~~~~~~~~~

The CCNC will test the Node circuit from the 202T at the Host site to
the 202T at the Node site. Since Host to Node (CCNC to MMOC) circuits
are official company services, the CCNC will refer all Node circuit
troubles to the SSC/MAC. The SSC/MAC is responsible for the testing and
follow up to restoration of these circuit troubles.

Although Node to PSAP circuit are official services, the MMOC will
refer PSAP circuit troubles to the appropriate SSC/MAC. The SSC/MAC is
responsible for testing and follow up to restoration of PSAP circuit
troubles.

The SSC/MAC will also receive reports from CRSAB/IMC(s) on subscriber
911 troubles when they are not line troubles. The SSC/MAC is
responsible for testing and restoration of these troubles.

Maintenance responsibilities are as follows:

SCC@ Voice Network (ANI to PSAP)
@SCC responsible for tandem switch

SSIM/I&M PSAP Equipment (Modems, CIU's, sets)
Vendor PSAP Equipment (when CPE)
SSC/MAC PSAP to Node circuits, and tan
