2.2. Feature Overview of R4 for DM3

IMPORTANT

The R4 API for DM3 is provided in a Dialogic software release that may contain additional restrictions than those listed here. A feature listed here as "supported" in R4 for DM3 may be listed in the Dialogic software Release Guide or Release Updates as "not supported" on DM3 boards. See these documents for details on additional restrictions, compatibility issues, and known problems.

The following is a summary of the features supported in R4 for DM3. The rest of this publication describes the differences between the R4 and the R4 for DM3 implementations.

NOTE

This release provides support for two types of routing configuration: fixed and flexible. Basically, fixed routing, which was the only configuration available in the first two System Releases containing R4 on DM3 (DNA 3.3 and SR 5.0), is a restricted routing, whereas flexible routing is compatible with the routing capabilities in the R4 API. These routing configurations are fully described in Section 12.1. Fixed and Flexible Routing Configurations.

Since the routing configuration affects the routing capability and resource management features that are supported, both routing configurations are documented in this Compatibility Guide. The routing information in this Compatibility Guide is presented under the assumption that flexible routing will be used. However, because fixed routing is an option, information on fixed routing is provided, although it is gathered entirely into Chapter 12. R4 on DM3 Resource Routing and Cluster Configuration.

The availability of flexible routing for a specific Dialogic product depends upon the Dialogic software release in which the product is supported. Fixed and flexible routing are supported on Dialogic products as indicated in the Dialogic software Release Guide and Release Updates, so refer to those documents for information on specific product support.

2.2.1. Basic System Features Supported

The following is a list of the system features that are supported in Windows:
