The copper shape files include coverage areas for:
- VDSL (based on 15db line attenuation) – only provided for VDSL capable cabinets
- 60db line attenuation (equates to >10mbps broadband in the coverage maps) – only provided for cabinets in the FTTN zone
- 70db line attenuation (equates to >5mbps broadband in the coverage maps) – only provided for Zone 4 cabinets
- 100db line attenuation (equates to >1mbps broadband in the coverage maps) – only provided for Zone 4 cabinets.
A CSV file is also provided that indicates which cabinets are part of the RBI program and the rollout year that they expected to be implemented/upgraded.
A premises falling outside of a coverage area does not indicate no copper service, it simply indicates that it is beyond a 100db line attenuation. This is indicative information only and a formal prequalification check using either OO&T or Chorus Portal is required to confirm service
