5.10 Data Types related to Time Synchronization |R18| p. 161
5.10.1 Introduction p. 161
This clause defines common data types related to Time Synchronization.
5.10.2 Simple Data Types p. 161
This clause specifies common simple data types.
| Type Name | Type Definition | Description |
|---|---|---|
| n/a |
5.10.3 Enumerations p. 162
5.10.3.1 Enumeration: SynchronizationState p. 162
| Enumeration value | Description |
|---|---|
| "LOCKED" | Locked, see TS 23.501 |
| "HOLDOVER" | Holdover, see TS 23.501 |
| "FREERUN" | Freerun, see TS 23.501 |
5.10.3.2 Enumeration: TimeSource p. 162
| Enumeration value | Description |
|---|---|
| "SYNC_E" | SyncE, see TS 23.501 |
| "PTP" | PTP, see TS 23.501 |
| "GNSS" | GNSS, see TS 23.501 |
| "ATOMIC_CLOCK" | atomic clock, see TS 23.501 |
| "TERRESTRIAL_RADIO" | terrestrial radio, see TS 23.501 |
| "SERIAL_TIME_CODE" | serial time code, see TS 23.501 |
| "NTP" | NTP, see TS 23.501 |
| "HAND_SET" | hand_set, see TS 23.501 |
| "OTHER" | other, see TS 23.501 |
5.10.3.3 Enumeration: ClockQualityDetailLevel p. 162
| Enumeration value | Description |
|---|---|
| "CLOCK_QUALITY_METRICS" | Clock Quality Metrics are to be provided to the UE |
| "ACCEPT_INDICATION" | Acceptable/not acceptable indication is to be provided to the UE |
5.10.3.4 Enumeration: ClockQualityDetailLevelRm p. 162
This enumeration is defined in the same way as the "ClockQualityDetailLevel" enumeration, but with the OpenAPI "nullable: true" property.
5.10.4 Structured Data Types p. 162
5.10.4.1 Type: ClockQualityAcceptanceCriterion p. 162
| Attribute name | Data type | P | Cardinality | Description |
|---|---|---|---|---|
| synchronizationState | array(SynchronizationState) | O | 1..N | Indicates the state of the node synchronization, represented by the values "LOCKED", "HOLDOVER", or "FREERUN" |
| clockQuality | ClockQuality | O | 0..1 | Clock Quality |
| parentTimeSource | array(TimeSource) | O | 1..N | Parent Time Source. |
5.10.4.1A Type: ClockQualityAcceptanceCriterionRm p. 163
Describes the modifications to the "ClockQualityAcceptanceCriterion" data type. This data type is defined in the same way as the "ClockQualityAcceptanceCriterion" data type, but:
- with the OpenAPI "nullable: true" property;
- the removable attributes "clockQuality" with the removable data types "ClockQualityRm"
- the removalble attributes "synchronizationState" and "parentTimeSource" with the OpenAPI "nullable: true" property.
| Attribute name | Data type | P | Cardinality | Description |
|---|---|---|---|---|
| synchronizationState | array(SynchronizationState) | O | 1..N |
Indicates the state of the node synchronization, represented by the values "LOCKED", "HOLDOVER", or "FREERUN"
(NOTE) |
| clockQuality | ClockQualityRm | O | 0..1 | Clock Quality |
| parentTimeSource | array(TimeSource) | O | 1..N | Parent Time Source
(NOTE) |
|
NOTE:
The attribute may be removed and need to be defined as nullable:true in the openAPI file.

5.10.4.2 Type: ClockQuality p. 163
| Attribute name | Data type | P | Cardinality | Description |
|---|---|---|---|---|
| traceabilityToGnss | boolean | O | 0..1 | true indicates yes false indicates no" |
| traceabilityToUtc | boolean | O | 0..1 | true indicates yes false indicates no |
| frequencyStability | Uint16 | O | 0..1 | see TS 23.501 |
| clockAccuracyIndex | string | O | 0..1 | string of two hexadecimal digits; see Table 5 of IEEE Std 1588 [51]. |
| clockAccuracyValue | integer | O | 0..1 | Indicates the absolute clock accuracy value. Unit in 25ns. Min: 1 Max: 40000000 |
5.10.4.2A Type: ClockQualityRm p. 163
Describes the modifications to the "ClockQuality" data type. This data type is defined in the same way as the "ClockQuality" data type, but:
- with the OpenAPI "nullable: true" property;
- the removable attribute "frequencyStability" with the removable data types "Uint16Rm"
- the removalble attributes "clockAccuracyValue" and "clockAccuracyIndex" with the OpenAPI "nullable: true" property.
| Attribute name | Data type | P | Cardinality | Description |
|---|---|---|---|---|
| traceabilityToGnss | boolean | O | 0..1 | true indicates yes false indicates no |
| traceabilityToUtc | boolean | O | 0..1 | true indicates yes false indicates no |
| frequencyStability | Uint16Rm | O | 0..1 | see TS 23.501 |
| clockAccuracyIndex | string | O | 0..1 |
string of two hexadecimal digits; see Table 5 of IEEE Std 1588 [51].
(NOTE) |
| clockAccuracyValue | integer | O | 0..1 | Indicates the absolute clock accuracy value. Unit in 25ns. Min: 1 Max: 40000000 (NOTE) |
|
NOTE:
The attribute may be removed and need to be defined as nullable:true in the openAPI file.
