6.5.2 ATM_MSG_CFG_STREAM – ATM Cell Stream Configuration
Synopsis
Message used to configure an ATM cell stream.
Format
Description
Processed by the module (once a module configuration message has been correctly processed) to configure
and activate an ATM cell stream (whether single TDM or IMA bundle).
After extraction of the message parameters (and in combination with the per module configuration options
described above), the module shall configure an ATM cell stream (as requested) and will activate the ATM cell
stream.
For the configuration of IMA bundles, TDM resources cannot be dynamically added or removed from an active
IMA bundle. To increase the bandwidth available via an IMA bundle, the bundle will have to be removed and
re-added.
The confirmation message (if requested) indicates success with a status value of 0.
