ITU-T H.248.11 PDF

This Recommendation describes a package for the ITU-T H.248.1 gateway protocol related to media gateway overload control. With the root termination implementing this package, a gateway is expected to report MG_Overload events to a media gateway controller.

The following MGC/MG characteristics are required for this package to work effectively:

1) The applications consist of individual point-to-point calls between two end users, and of calls involving several additional call legs (for example, a conference call where an MG hosts a conference bridge).

2) Point-to-point call set-up using an MG typically involves no more than two ADD commands requested by its MGC.

An example of the applications covered by such an MGC is real-time conversational voice transported using TDM, ATM, IP or frame relay.
