How it works

Chorus Relay Connect transports traffic between Points of Interconnection (POI) in different UFB Candidate Areas.

CRC

It is provided from exchange to exchange in specified locations. The expected termination point is within the Service Provider’s Central Office Co-location Service footprint in a Chorus POI Central Office. The connection may be extended beyond the POI within the Candidate Area using one of the following.

  • Chorus Data Centre Connect to a data centre within Chorus POI Central Office area where available; or
  • Intra Candidate Area Backhaul Service to another Chorus Central Office where available; or
  • Direct Fibre Access Service to site within Chorus POI Central Office area where available; or
  • Third party backhaul; or
  • Chorus Exchange Connect.
