HAPTER 12 other records outside the scope of the standard are also included but are not meant to be inclusive or complete. There is no ques- tion that properly designed administrative systems will have to incorporate many of the non-mandatory advisory elements in- cluded within the standard. In order to associate various applications with the telecom- munications infrastructure, user codes identifying and linking circuit information, such as voice or data, may be included. Com- bining both physical and logical information is important for telecommunications administration, especially when generating trouble tickets for network fault management and when generat- ing work orders for adds, moves and changes. Being able to quickly determine which circuits are available, reserved, in use or out of use is an important part of telecommunications infra- structure management. The following reports are recommended by the standard: pathway, space, cable, end-to-end circuit, cross-connect and grounding/bonding summary reports. The recommended content of the reports includes: Pathway reports: List all pathways and include type, present fill and load. Space reports: List all spaces, types and locations. Cable reports: List all cables, types and termination positions. End-to-end circuit reports: Trace connectivity from end-to- end and list user codes, associated termination positions and cables. Cross-connect reports: List all cross-connections within each space. Grounding/bonding summary reports: List all grounding busbars and attached backbone bonding conductors. The Telecom Handbook x 267 CABLE Additional and optional information can be presented in these reports. Also, the reports described in the standard are not all- inclusive. Many other reports not mentioned in the standard would normally be included as part of a properly designed telecommu- nications infrastructure administration system. Conceptual and installation drawings are considered input to the final record drawings which graphically document the tele- communica
