Intellectual Property Rights
IPRs essential or potentially essential to the present document may have been declared to ETSI. The information
pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (http://webapp.etsi.org/IPR/home.asp).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee
can be given as to the existence of other IPRs not referenced in ETSI SR 000 314 (or the updates on the ETSI Web
server) which are, or may be, or may become, essential to the present document.
Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Telecommunications and Internet
converged Services and Protocols for Advanced Networking (TISPAN).
This technical specification was previously published as a Technical Report.

1 Scope
The purpose of the present document is to define guidelines with regard to the interaction of non-call related H.248
procedures and generic network management use cases and vice versa. More specifically, the interaction between the
following is considered:
• Control procedures at the H.248 interface. These are the procedures between Media Gateway Controllers
(primary and secondary) and their associated Media Gateways (primary, and secondary if available). These
procedures primarily utilize the H.248 ServiceChange and H.248 Audit procedures.
• Management procedures at the management interface(s) of H.248 systems (i.e. both Media Gateway
Controller and Media Gateway) to perform non call related tasks such as configuration management (start-up,
capability change, maintenance locking) and fault management (failure handling).
It is intended that these guidelines are then subsequently used in corresponding H.248 profiles to produce detailed
non-call related procedures. At the current time, the existing set of ETSI H.248 profiles ( [i.1], [i.2], [i.3] and [i.4]) lack
any such detailed procedures.
Specific management systems, architectures and protocols are outside the scope of the present document; only the
general requirements and Use Cases related to the management system shall be discussed.
1.1 Applicability
The present document is applicable to any network element that exhibits a H.248 interface and a management interface
(e.g. SNMP). The intent of the present document is to provide guidelines so as to facilitate a consistent set of behaviour
for non-call related procedures in the related H.248 profile specifications. Due to the general nature of the present
document, it is possible that some of the procedures herein will not be applicable to certain H.248 profiles - it is for a
specific profile itself to define which procedures are mandatory/optional/not applicable.
The present document assumes an IP-based transport for H.248 signalling. The IP transport may be provided by either
UDP or SCTP.
1.2 Relation to H.248 Standards
The present document is considered to be complementary to H.248 standards where there are discrepancies between the
present document and the correspondent ITU-T Recommendation H.248 series Recommendations, the procedures of
these ITU-T Recommendations (in particular ITU-T Recommendation H.248.1 [i.5] and its annex F on ServiceChange),
take precedence over those described in the present document.
