SIST EN 300 377-1 V1.2.1:2003 is the SIST version of ETSI EN 300 377-1 for the Telecommunications Management Network (TMN) Q3 interface at the Local Exchange (LE). It specifies the interface model used for configuration management of V5 interfaces and the associated customer profiles. It is written for TMN implementers, network operators, and LE or Access Network (AN) management systems that need to provision, reconfigure, and monitor V5 access services.
What does SIST EN 300 377-1 V1.2.1:2003 specify?
SIST EN 300 377-1 V1.2.1:2003 specifies the Q3 interface between an LE and the TMN for configuration management of V5.1 and V5.2 interfaces and their associated customer profiles. The document focuses on object models and management behavior, while related transmission, media, and non-V5 service management remain outside its scope.
The document is organized into scope, references, definitions, information model diagrams, information model description, formal managed object class definitions, and protocol requirements. Its annexes then map state machines and message flows to the management model used in practice.
| Annex | What it covers |
|---|---|
| Annex A | Mapping of management primitives for user port FSM state transitions for virtual analogue, virtual basic rate, and virtual primary rate accesses |
| Annex B | Mapping of link control states onto X.731 states, for AN and LE |
| Annex C | TMN management service for customer administration at the V5 interface and V5-related data at the LE |
| Annex D | Functional architecture |
| Annex E | Link control message flows |
| Annex F | Message flows for mapping virtual access ports onto ITU-T Recommendation X.731 states |
What are the key requirements of SIST EN 300 377-1 V1.2.1:2003?
SIST EN 300 377-1 V1.2.1:2003 defines the managed objects, attributes, actions, and notifications needed to manage V5 configuration consistently across the LE and TMN. In practice, this is what an implementation must model to keep access, channel, and protection data aligned.
- Clause 4 sets out the entity relationship, inheritance, and naming hierarchies. This matters because the management system must know which objects contain others and which objects are linked by peer or group relationships.
- Clause 5 defines the main managed objects, including
v5Interface,v5Ttp,v5TimeSlot,commChannel,commPath,v5ProtectionGroup, andv5ProtectionUnit. This is the core of the configuration model used by the Q3 interface. v5Interfacerepresents a V5.1 or V5.2 interface and is linked to the relevant virtual access ports and 2 Mbit/s links. The document uses reciprocal pointer actions to keep these relations synchronized.- State handling is central.
operationalState,administrativeState, andavailabilityStatusare used to reflect enabling, blocking, shutdown, degradation, and dependency conditions, so operators can see whether service is available and why. v5Ttprepresents the 2 Mbit/s interface and contains 31v5TimeSlotobjects.v5TimeSlotrepresents a 64 kbit/s bearer channel or a C-channel, so implementations must treat bearer and signaling paths differently.- The communication path model separates ISDN, PSTN, control, BCC, link control, and protection signaling. This is important because different signaling types are tracked and managed separately on the V5 interface.
v5Provisionand the related actions support synchronized reconfiguration through provisioning variant exchange. That lets the two ends of the interface coordinate changes instead of changing independently.- Annexes A and B provide the state-mapping rules that implementers use when translating management actions into FSM behavior and X.731 state changes.
What terms does SIST EN 300 377-1 V1.2.1:2003 define?
SIST EN 300 377-1 V1.2.1:2003 defines the V5 and TMN terms needed to describe the interface model.
- Telecommunications Management Network (TMN) - The management framework used to supervise and configure the network elements.
- Local Exchange (LE) - The exchange side where the V5 interface is managed.
- Access Network (AN) - The access side connected to the LE through the V5 interface.
- V5TTP - A 2 Mbit/s interface object that represents the V5 link and contains 31
v5TimeSlotobjects. - v5TimeSlot - A 64 kbit/s channel on the V5 interface used either as a bearer channel or as a C-channel.
- virtualAccessPortR1 - An image of the customer access port located in the AN and connected to the LE through V5.
- commChannel - The object that represents a V5 C-channel and multiplexes one or more
commPathobjects. - v5ProtectionGroup - The object that groups protected and protecting units for V5.2 protection switching.
Who uses SIST EN 300 377-1 V1.2.1:2003?
SIST EN 300 377-1 V1.2.1:2003 is used by network operators, TMN and OS designers, and vendors implementing LE or AN management functions for telephone networks. It is used when provisioning customer access, assigning V5 channels and timeslots, managing reconfiguration, and handling protection switching or link state changes. It is also relevant to teams integrating customer administration with V5.1 and V5.2 interface control.
Which standards are used with SIST EN 300 377-1 V1.2.1:2003?
SIST EN 300 377-1 V1.2.1:2003 relies on companion ETSI and ITU-T documents for the wider TMN and V5 model, especially EN 300 291-1, EN 300 324-1, EN 300 347-1, EN 300 376-1, EN 300 378-1, EN 300 379-1, ITU-T M.3010, ITU-T M.3100, ITU-T Q.811, ITU-T Q.812, ITU-T X.208, ITU-T X.720, ITU-T X.721, ITU-T X.730, ITU-T X.731, ITU-T X.732, ITU-T Q.824.5, and ITU-T Q.824.0. These references provide the customer administration model, V5.1 and V5.2 interface definitions, TMN principles, information modeling rules, protocol profiles, and the shared state and relationship semantics used by this standard.
What does the SIST EN 300 377-1 V1.2.1:2003 document contain?
SIST EN 300 377-1 V1.2.1:2003 contains information model diagrams, detailed managed object class descriptions, formal object class definitions, actions, notifications, and protocol requirements. It also includes annexes with state-transition tables and message-flow tables for blocking, unblocking, shutdown, link ID checking, provisioning variant exchange, and protection switching. Annex C adds a service-oriented view of customer administration tasks at the V5 interface.
