AMIS Networking
As more advanced features have been added to the DOS®-based Stratagy systems, memory
management has become a critical issue in software development. Because of this, TAIS/TSD
looks toward feature interaction as a way to create more operating system memory when
developing new features. With the addition of the Call Record feature to the DOS-based products
with Release 3.3 software, the number of default Audio Messaging Interchange Specification
( AMIS) networking nodes has been reduced to 200. In addition, further restriction to the number of
AMIS networking nodes will be required to support Stratagy DK systems with multi-lingual
prompts.
The fewer AMIS nodes the system is configured for, the more operating system memory is
available for other features. The Stratagy systems reserve enough operating system memory to run
the number of AMIS nodes specified in the amis_max_nodes parameter in the Stratagy System
Configuration. Additionally, a system using more features and a higher configuration requires
more operating system memory. For example, an eight port Stratagy DK system with a high
amount of call traffic using the new Call Record feature requires more operating system memory
than a system with fewer ports and/or less traffic. Multi-lingual prompts have been specifically
identified as a feature that requires a reduction in the number of AMIS nodes to increase Operating
System (OS) memory for proper system operation.
Due to the number of feature configurations possible in a Stratagy system, it is not possible for
TAIS/TSD to accurately identify the correct number of AMIS nodes in each case. If the system
you are working on runs out of OS memory, the failure causes the system to continually reboot. To
correct this, the number of AMIS nodes must be reduced.
