Debswana is the world's leading diamond producer by value and has played a significant role in the transformation of Botswana’s economy that it was. It is the largest non-government employer and the largest earner of foreign exchange in Botswana.

Debswana's mining operations have been largely responsible for transforming Botswana from an agriculturally based economy in the 1960s to a country that has consistently displayed one of the highest economic growth rates in the world.

The N-8000 Series IP Network Intercom offers flexible communications for up to 1280 stations on existing corporate local and wide area data networks. Built on TOA’s proven NX-100 network audio technology, the new IP Intercom products occupy minimal network bandwidth (130 kbps maximum) for station-to-station calls and can be controlled and monitored through software or web browser. Programmable system functions include 160 paging zones, time-based call forwarding and scan monitoring.

The backbone of the new system is the compact N-8000EX Exchange which supports 16 stations and occupies only one rack space. Features include a 10/100BaseT port for connection to standard network hardware and two paging audio outputs. Larger systems can be easily configured with up to 80 exchanges and 1,280 stations. The economy N-8010EX IP Intercom Exchange, featuring one speech link, is available as a lower-cost alternative to the four-link N-8000EX IP Intercom Exchange. The N-8000MI Multi-Interface Unit features telephone interface, BGM input, paging outputs, control signaling plus functions as an interface to legacy TOA EXES intercom systems.
