An inter-building pathway element is a cabling support vessel that typically connects one buildings space to another buildings space. The format for the inter-building pathway element shall be [b1-fs1]/[b2-fs2]-UUU.n.d(q), where:
b1fs1 = building identifier and TS identifier for the TS in which one end of the backbone cable is terminated
b2fs2 = building identifier and TS identifier for the TS in which the other end of the backbone cable is terminated
UUU = a user defined identifier referring to the type of element (descriptor) n = two to four numeric characters identifying the pathway element (major ID) d = detail information such as port, sub-duct, optical fiber and pair (minor ID) q = qualifying information
The pathway records shall contain the following information:
•inter-building pathway identifier (primary indexing identifier,
e.g., ADM-3A/ENG-3B-CT01)
•pathway type (e.g.: Cable Tray)
•pathway fill (e.g.: 20%)
•pathway loading
•cable records
•space record1 (e.g.: ADM-3A)
•space record2 (e.g.: ENG-3B)
•grounding record
Additional items of information desired by the system owner or operator may be added to each record, such as:
•pathway length (e.g.: 40m (132ft))
•pathway max fill (e.g.: 40%)
•pathway max load
•pathway condition
•number of bends
•firestopping records
