H.248 Address Reporting Package

The package command enables the DBE to use the optional eroot package.

H.248 Address Reporting Package

The H.248 Address Reporting Package is described in the “H.248 Address Reporting Package” section on page 8-2.

H.248 Gate Information (Ginfo) Package Becomes Optional

This enhancement removes the stipulation that the Gate Information (Ginfo) package properties are required in the DBE H.248 profile. The DBE continues to support the Ginfo package properties as optional properties and supplies default values if values are not specified.

The Ginfo package properties are the following:

•bill_corr property is defaulted to a value of 24 zero bytes.

•gate_state property is defaulted to COMMITTED. The termination is maintained across system failover and H.248 association loss at all times after the initial termination add. Changes to committed gates are replicated to the redundant card immediately. Therefore omitting this property has a minor performance overhead on redundant systems.

•gate_side property is defaulted to SIDE_A for the first termination in a stream and to SIDE_B for the second termination in a stream.

DBE Restrictions

The following is a restriction of DBE support for the H.248 Gate Information Package Becomes Optional feature:

•If one of the Ginfo properties is omitted when adding a termination, you cannot later specify a value for that property value on an Add termination request. An attempt to do fails with error 421 indicating “Unknown action or illegal combination of actions.”

H.248 Segmentation Package Support

When an H.248 association is established over the User Datagram Protocol (UDP), the H.248 message can be too big to fit inside one UDP packet, and as a result, H.248-based segmentation is required. The H.248 Segmentation (seg) package, defined in H.248.1v3 Annex E, defines the following four properties to use when performing this segmentation:

•MGSegmentationTimerValue

•MGCSegmentationTimerValue

•MGMaxPDUSize

•MGCMaxPDUSize
