58 System architecture
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.
The data dump program is also used to install a new generic version or
issue and capture protected data store information (such as speed call
lists) that may be changed by a user.
Software audit
This program monitors system operation and gives an indication of the
general state of the system operation. The program is concerned mainly
with the system software. When a software problem is encountered, the
program attempts to clear the problem automatically.
Configuration options
Large Systems offer the following configuration options to support
increased system redundancy:
• “Fiber Remote IPE” (page 58)
• “Carrier Remote IPE” (page 61)
•
“Branch Office” (page 62)
•
“Geographic Redundancy” (page 62)
Fiber Remote IPE
Large Systems can be configured in a distributed system to support
remote subscribers, using Remote IPE modules or small cabinets.
Fiber-optic links are used to connect the Remote IPE modules and small
cabinets to the PBXs.
