All telephones on the DIT network begin with the prefix 402 and have a 4 digit extension.
The majority of telephones feature DDI (Direct Dial Inwards) extensions.
This means that if you are dialling another DIT extension internally, you can dial the 4 digit extension without needing the 402 prefix. An internal call between extensions incurs no cost.
With DDI, if somebody wants to call you directly from outside DIT, they can call 402 and replace the switchboard extension (3000) with your 4 digit extension.
