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.
