58 System architecture
Software programs provide the system interface for maintenance, service
change, and traffic measurement. Each program is independent and
has its own specific set of commands and formats. These programs run
concurrently with normal call processing without interfering with system
traffic.
There are five main categories of nonresident programs:
• service change and print routines
• maintenance diagnostics
• traffic
• equipment data dump
• software audit
Service change and print routines
Service changes do not usually require hardware changes. Instead, the
service administration programs are used to create or modify all aspects
of the system from individual feature key assignments to complete system
configurations. There are also programs and print routines for retrieving
data from the system to check the status of office data assignments.
Maintenance diagnostics
These programs are the primary instrument for clearing system faults.
Individual programs are used for automatically or manually testing the
Common Equipment and IPE. The programs can be loaded into the
overlay area at the request of maintenance personnel, or as part of a daily
maintenance routine automatically initiated by the system at a specified
time. In addition, background and signaling diagnostic routines can occupy
the overlay area when it is not in use.
Traffic
All systems are equipped with traffic data accumulation programs. There is
also a resident traffic print program that examines the schedules, transfers
data from accumulating to holding registers in accordance with schedules,
and prints the traffic data. In addition, there is a traffic program used to
query and modify schedules, options, and thresholds.
Equipment data dump
After making service changes, the changes must be saved to disk in order
to save them. When the equipment data dump program is run, all the office
data in the read/write memory is written to the system disk. The program can
be run automatically during the midnight routine or on a conditional basis
(for example, a data dump would only occur if a software service change
has been made). It can also be run manually through the system terminal.
