The only authoritative source of Telstra’s telecommunications data and the DSL landscape

ExchangeInfo™ Australia

ExchangeInfo Australia (and ExchangeInfo Plus) is an authoritative spatial data solution that incorporates Telstra’s infrastructure data to map out the telecommunications landscape. This allows organisations to accurately target potential customers by using phone details to form a spatial correlation.

ExchangeInfo enables telecommunications carriers to make more informed decisions about network planning, market-driven tower rollouts and product/service strategies for wireless and fixed networks. It is also a critical dataset in targeting new DSL prospects and ‘the last mile’ network planning.

ExhangeInfo Plus contains the same information found in ExchangeInfo, but goes one step further by providing additional strategic service information exclusively for Telstra Wholesale DSL lines and Virtual ISP customers.
