Technical specifications
This appendix covers the following technical specifications for the CC MIS system:
• real-time performance
•

reliability

• personal computer support
• power requirements
• environmental requirements
Real-time performance
CC MIS is a message-driven system. Messages received from the DMS-ACD translate into many
intertask messages that are used to drive the CC MIS Supervisor displays and other internal soft-
ware. The real-time performance of the system depends largely on two factors, the message arrival
rate (MAR) and the message service rate (MSR).
Reliability
Consistent configuration data
ACD configuration data in the DMS-ACD and in the CC MIS system are kept consistent with one
another. The DMS-ACD maintains a master copy of the configuration data. This data will be re-
quested by the CC MIS whenever it initializes for any reason, such as recovery after the failure of
the DATA LINK or the application software. If the DMS-ACD should initialize for any reason,
then CC MIS will take down the application software and request that the configuration data be
sent.
CC MIS has disk mirroring capability. Disk mirroring provides increased data protection and soft-
ware/data availability. Disk Mirroring is provided by RAID hardware.
Note:
CC MIS Maintenance Guide
Disk mirroring is a purchasable option.
