This Recommendation 1 describes a lightweight directory access protocol (LDAP) schema to represent non-standard multimedia communications endpoints, and is meant to provide a very basic framework for representing these elements in a directory. It is an auxiliary class related to [ITU-T H.350] and derives much of its functionality from that architecture. Implementers should review [ITU-T H.350] in detail before proceeding with this Recommendation.

This Recommendation 1 describes a simple lightweight directory access protocol (LDAP) and ITU-T X.500 schemas to represent call forwarding and call preference information in an ITU-T H.350 directory. It is intended to represent addresses to which calls should be forwarded in the case that an endpoint does not answer a call. It can direct calls to simple ITU-T H.320, ITU-T H.323 or session initiation protocol (SIP) addresses, or complex forwarding schemes such as time of day preferences, web pages, electronic mail or other applications. Implementers should review [ITU-T H.350] in detail before proceeding with this Recommendation.

This Recommendation 1 describes a lightweight directory access protocol (LDAP) schema to represent ITU-T H.320 endpoints. It is an auxiliary class related to [ITU-T H.350] and derives much of its functionality from that architecture. Implementers should review [ITU-T H.350] in detail before proceeding with this Recommendation. Its attributes include basic ITU-T H.320 address elements. These addresses can be downloaded to an endpoint for automatic configuration or published to white pages to create user dialling directories

This Recommendation 1 describes a lightweight directory access protocol (LDAP) schema to represent ITU-T H.235 elements. It is an auxiliary class related to [ITU-T H.350] and derives much of its functionality from that architecture. Implementers should review [ITU-T H.350] in detail before proceeding with this Recommendation. Its attributes include ITU-T H.235 identity, password and certificate elements. These aliases can be downloaded to an endpoint for automatic configuration or accessed by a gatekeeper for call signalling and authentication.

This Recommendation describes the requirements and the mechanisms for object mapping using IPv6 in next generation networks (NGNs). This Recommendation covers the following: Basic concept and requirements of object mapping using IPv6; Mapping architecture and relationships between identifiers; Mechanisms for object mapping using IPv6. This Recommendation does not intend to develop any specific protocols for object mapping. As many new types of devices (i.e., objects) are connected to networks, this Recommendation assumes that IPv6 plays a key role in object-to-object communications. The objective of this Recommendation is to provide guidelines for mapping of information on objects for providing end to-end connectivity in IPv6-based NGN.

The present Recommendation describes the subsystem configurations and benchmarks to establish a performance benchmark for an initial release of a PSTN/ISDN emulation subsystem (PES). The same tests can be used also for legacy PSTN/ISDN networks or for interworking tests between a PSTN/ISDN emulation subsystem and legacy PSTN and ISDN. The metrics measured and reported are for performance of this subsystem under a communications application load. This Recommendation covers the second of the following four performance aspects: Core Concepts;Subsystem configurations and benchmarks;Traffic sets and traffic profiles;Reference load network quality parameters.

A passive optical network has a shared medium in the upstream direction, and the passive ODN combines all ONU outputs towards the OLT. Therefore, an ONU that is not transmitting in a manner consistent with parameters specified in the standard can threaten all upstream transmissions on the PON causing interference and disrupting communications of all ONUs on the PON. An ONU that transmits optical power up the PON in violation of the parameters of the standard is called a "rogue ONU". This kind of situation is not unique to PONs, as many wireless and RF-based systems use the same shared channel scheme. However, under certain hardware and software conditions (attributed to circumstances including design, manufacturing, device failure, environmental, external, or other influences), an ONU may exhibit behaviour that disrupts the operation of other ONUs on the same PON. Such rogue ONU behaviour can cause performance issues or outages for one or more ONUs on the PON. Also, diagnosing and isolating the offending ONU can be difficult since the affected ONUs are not always the ONUs causing the disruption. This Supplement raises the awareness of rogue ONU behaviour and provides system designers and implementers with techniques and tools to facilitate the prevention, detection, isolation, and removal of the offending ONU to avert or minimize service interruptions to other ONUs on the PON. This treatment distinguishes a rogue ONU from a unit that intentionally or maliciously transmits optical signals that are not in accordance with the standard. In the strictest sense, these devices or intentional jammers are not ONUs, since they are not following the ITU-T Recommendations that describe ONUs. They are essentially illegal devices that intend to deny or steal service from the network. However, these devices may exhibit behaviour and use processes that are similar to rogue ONUs and, therefore, considerations contained in this Supplement may assist in mitigating their potential impact. Security measures are specified in the standard to further assist in reducing threats from malicious sources. The following clauses consider several rogue conditions that can occur and the design measures that can be employed to address them. Rogue ONU prevention, detection, isolation, and mitigation techniques are intended to avert or minimize service interruptions on a PON when a rogue condition occurs, and are not intended to be a substitute for solid engineering practice and adherence to the standards. Clause 4 provides the expansion of abbreviations and acronyms.

This Recommendation provides the functional components, based on [ITU-T G.805], that are necessary to describe the deployment of Multi-Protocol Label Switching Transport Profile (MPLS-TP) in a transport network. This model allows MPLS-TP to be modelled in a way that is consistent with the description of other transport technologies defined by ITU-T, (e.g., the synchronous digital hierarchy (SDH), the optical transport network (OTN), etc.).

This Recommendation describes the framework of mobility management (MM) in the service stratum for next generation networks (NGNs). This Recommendation addresses the issues on terminal mobility based on the IP multimedia subsystem (IMS). This Recommendation first identifies the functional architecture of MM in the NGN service stratum, and then specifies the procedural information flows for location management and handover control based on the identified functional architecture.
