H.248 Traffic Management Package Support

H.248 Traffic Management Package Support

The DBE supports the sustained data rate (tman/sdr), maximum burst size (tman/mbs), and policing (tman/pol) properties of the ETSI TS 102 333 Traffic Management (Tman) package.1 Support of these tman properties allows additional pinhole programming in the Tman package to inform the DBE how to police media and signaling flows. These tman properties can be assigned to both media and signaling flows. The DBE performs asymmetric flow policing.

The Traffic Management package is described in the “H.248 Traffic Management Package Support” section on page 5-1.

H.248.1v3 Support

H.248.1v3 Support allows the DBE to interoperate with an SBE, which requires H.248.1v3 or Media Gateway Controller (MGC) version 3. The DBE can only accept version 3 once it is configured to support version 3.

On contacting an SBE, the DBE advertises for H.248.1 version 3 and confirms the version received in the response from the SBE. If the SBE supports a lower version than was advertised, the DBE logs the event, disconnects from the SBE, and tries an alternative SBE until an SBE with H.248.1v3 is found. A new field, bcaGalEntMegacoVersion, is added to the MG-Abstraction Layer entity MIB.

DBE Restrictions

The following is a restriction of H.248.1v3 Support:

•The DBE rejects attempts to negotiate with the MGC to a lower version once the DBE is configured to support version 3.

Related Commands

The h248-versioncommand defines the version of the H.248 protocol which the DBE uses when forming associations with an H.248 controller.

H.248 VLAN Package Syntax-Level Support

The DBE provides syntax-level support of the H.248 VLAN package. The media gateway controller (MGC) can program up to two VLAN tags and associated Ethernet priorities, as defined in the H.248 VLAN package. The DBE can accept, store, and return VLAN tag and priority information, at the syntax level, for media streams.

DBE Restrictions

The following is a restriction of DBE support for the H.248 VLAN package:

•The DBE does not use the VLAN tag and priority information.
