There are currently two TSO deeds for services:
- Telecommunications Relay Services (TRS) deed for the hearing impaired which is between the Crown and Sprint
- Local Residential Telephone Services (LRTS) deed which is between the Crown, Telecom and Chorus
The cost of the TRS TSO is paid for by the Crown from the Telecommunications Development Levy (TDL). The Commission prepares a TRS cost calculation each year to determine how much the Crown owes for these services. This cost calculation is completed after the annual TDL liability allocation determination is publicly notified.
The Crown will not pay for LRTS unless the TSO provider requests a cost calculation under section 94 of the Telecommunications Act 2001.
The TRS Cost Calculations for the past three years can be found below. Older calculations can be found in the Telecommunications Archive.
