Shared site infrastructure, routes and ducts

Record physical structures, explicit placement relationships and cable routes.

Last updated: 10 November 2026

Physical records and relationships

Shared site records include structures such as POP / exchange, Site, Building, Site cabinet, Manhole, Handhole and Pole, together with Trench route, Aerial line and Duct / conduit lines.

Proximity or overlapping lines on the map do not create relationships. A splice closure's containing structure and a cable's route must be recorded explicitly. Candidate lists help you make a selection.

Place a feature inside a structure

1. In Edit mode, open the card of the point feature to place.
2. Select Place inside a structure.
3. Select the correct Containing structure. The list is ordered by distance.
4. Select Place.
5. Check the placement information in the card.

Placement states which structure contains the feature. Define fiber splice or patch connections separately through Splices, ODFs and racks.

Build the route

A fiber cable route may contain trench or aerial line segments. A duct route consists of trench segments. A cable can pass through a trench segment directly or through a duct recorded in that segment.

1. Select Edit under Route in the cable or duct card.
2. Add a record from Add segment…. You can also use Find candidates to inspect suggested segments along the geometry.
3. After selecting candidates, use Add selected items in order.
4. Adjust traversal order with Up and Down; use Remove for unwanted segments.
5. For cable trench segments, select direct (no duct) or the appropriate duct. Specify the subduct if known.
6. Select Save.

If duct options cannot be read, use Try again or remove that row. Do not assume the route has been saved while unreadable options remain.

Read continuity and quantities

Continuity in the card assesses transitions between segments and, where applicable, whether the route reaches the cable endpoints. Review discontinuous or could not be assessed explanations. A route record does not automatically complete missing parts of the drawing.

Bill of quantities (BoQ) shows the length together with its source. A measured or design length is used when available; otherwise the route or map provides an estimate. partial estimate means missing transitions are excluded from the total. Cable slack and vertical rises are added to estimates; they are not added again to a recorded total physical length.

Manage subducts

Sub-ducts in a Duct / conduit card shows numbers, statuses, cable provision and usage by segment. Use Edit to change status, cable provision, colour and diameter. A subduct number is its permanent identity; changing list order does not renumber it.

Existing cables in a faulty or reserved subduct remain, but new cable assignments are blocked. no assignment is not proof of physical vacancy or suitability for sharing. The application does not assess sharing suitability.

If a source reports only the number of occupied subducts, the occupied channels may be unknown. Read Reconcile source and save your decision with Reconcile. A change in source occupancy invalidates the previous reconciliation.

Routes through this segment in a trench or aerial line card shows ducts and cables recorded against that segment. See Quantities and network occupancy for project totals.
