Calls within a single area code can be made by dialling the seven-digit subscriber number alone. For long-distance calls, callers from landline numbers dial the long-distance prefix 8, wait for a tone, and then dial the zone code and number. Modern exchanges no longer require waiting for the tone, nor does mobile telephony where the long ...

The system was based on fixed-length numbers; a direct-dial long-distance call consisted of a three-digit area code and a seven-digit local number.

The call is carried over the PSTN using a 64 kbit/s channel, originally designed by Bell Labs.
