Idea: use augment for name/extension attributes - instead of documentation out side of UML and YANG

Addresses the limitations (rw/ro, units, ...)

• Equipment as part 2.0
• Next step: generating to yang
• Decision: existing attributes documented in TransmitterEquipment document should be modeled in Equipment Augment.  
• Discussion of Equipment #15

Sequence-Id (related to Equipment #17, Equipment #18)

• Used to uniformly address connectors and contained-holders across devices of the same type / model.
• A use case might be using SDN data in an external inventory & planning application, where LTP data on connector level could be mapped to existing planning data. As port label texts and data models vary between applications and ONF, a uniform address scheme is needed.
• Identification of connectors and contained holders independent of proprietary label strings.
• Each object (connector and holder) on one level (sharing the same parent object) should have a unique sequence-id.

Next Step:

• create an issue which clarifies #17 and #18 and adds a new attribute for the sequence-id to the Equipment_Augment.
• #17 > sequence-id is part of CoreModlel "name"  → revert #17 and update #17 instead of creating a new issue
  • important the concept itself does not change and all the description must be in the description of the attribute "sequence-id"
• #18 remains because the examples cant be part of a pure textual description UML and YANG

Info: 

• VLAN is not recommended BoundaryClock by other Alliance WG9 (Transport)
• VLAN is allowed for TransparentClock by O-RAN Alliance WG9 (Transport)

Please see: https://orandownloadsweb.azurewebsites.net/specifications
O-RAN Synchronization Architecture and Solution Specification 2.0
O-RAN.WG9.XTRP-SYN.0-v02.00 - look for "PTP over VLAN".

Comments could be addressed by adding issues in GitHub.

• Backup and Restore Operations

  • backup configuration to FTP server
  • restore configuration from FTP server AND activate
  • abord operation individual for backup and restore
  • rollback to previous configuration stored in the device
  • applyRestoreOperation
• Note: Mediator Instance Manager backup-and-restore functions are covered by app and cloud functions
  
  

• status

  • backupOperationStatus
  • restoreOperationStatus
