Remote Maintenance R-7
R-7 Remote Maintenance
General Description
This feature allows office data changes or reassignments to be performed without a site visit by service personnel,
and can be used to detect fault tendencies before they affect service. One REMOTE MAINTENANCE center can
service an unlimited amount of systems, thus reducing the amount of personnel needed to maintain each site.
Operating Procedure
The operation of this feature involves the use of the MAINTENANCE ADMINISTRATION TERMINAL (MAT)
[M-18].
Service Conditions
1. The following additional equipment is required for this feature:
a.) a modem at the maintenance center, and one at each remote site,
b.) a dedicated or non-dedicated telephone line for each remote site.
2. The following operations can be executed from the REMOTE MAINTENANCE location:
a.) list of all system data (line, trunk, etc.)
b.) retrieval of fault data
c.) retrieval of traffic management information
d.) testing of system operation
e.) deletion or addition of system data (line, trunk, etc.) using a pre-programmed security password
3. The following three facility methods are available to interface with a remote test location:
a.) dedicated connection
b.) dial-up connection - TIE Line
c.) dial-up connection - CO Line
4. Maintenance testing can be performed at a remote central facility, using the MAT [M-18] to evaluate a
trouble report, prior to the dispatching of a repair person to the customer location.
5. Two MATs can access a system simultaneously, provided they are not using the same command at the
same time.
Interactions
AUIDN must be assigned before allowing the password function in the ASYD command. If password is allowed in
ASYD before AUIDN is assigned, Error Message 0550 “Password not yet assigned”, will be displayed.
