Chapter 7 H.248 Services—Signaling and Control

Multi-Stream Terminations

•Requested address or port is already in use by another flow, or was in use by a recently deleted flow. Megaco error 510 “Insufficient Resources.”

DBE Restrictions

The following are restrictions of DBE support for this feature:

•The addresses and ports specified must fall within a valid address or port range configured on the DBE, and not marked as “MGC-managed.”

•The class of service of the port range must match the type of flow being allocated.

•Real-time Transport Protocol (RTP) flows cannot be set up to use odd-numbered ports.

Multi-Stream Terminations

This enhancement allows a single H.248 termination to contain multiple streams. Previously, only a single stream for each termination was allowed, which meant that multi-stream calls needed to be signaled using multiple pairs of terminations. This enhancement supports the new H.248.1v3 syntax in which several streams can occupy the same termination.

DBE Restrictions

The following is a restriction of DBE support for this feature:

•Auditing of per-stream statistics is only supported when using H.248.1v3. This is a restriction of the H.248 protocol.

Nine-Tier Termination Name Hierarchy

The Nine-Tier Termination Name Hierarchy feature adds support for a nine-tier termination name schema, where the multi-tier prefix is supplied by the media gateway controller (MGC), and the final element, the channel ID, is generated by the media gateway (MG). All MGCs that the MG is configured to contact must use the same termination name schema. A termination is the point of entry or exit of media flows relative to the MG. The MG understands how the flows entering and leaving each termination are related to each other.

This feature plays an important role in identifying the company, transaction service (such as voice or video), and termination attributes (such as access, backbone, etc.).

Restrictions for Nine-Tier Termination Name Hierarchy

•Only the final element may contain the CHOOSE ($) wildcard. The DBE will not extract any meaning from any elements of the termination ID. The exception: “ * “ is reserved for wildcard notation.

•Multi-tier prefixes can be less than nine tiers, but must have the same depth.
