4-32 Chapter 4Business Features PackageOne-Time Do Not DisturbThe Do Not Disturb (One Time) feature is used to stop all calls to a station when the user ison an outside line and does not want to be disturbed for the duration of the call. Upon com-pletion of the call, DND is cancelled and the station is returned to normal service. This fea-ture requires a programmed key.One-Touch Dialling KeysFrequently-used speed dial numbers can be assigned to one-touch dialling keys for fast ac-curate dialling.On-Hook DiallingAny keyset user can originate calls without lifting the handset. When the called party answers,the user may speak into the microphone or lift the handset for more privacy.Programmable KeysKeysets have a number of programmable keys. The number depends on the type of keyset,e.g. 14 (DS-5014D), 21 (DS-5021D), 24B (Euro), 12B (Euro), and so on. To personalise akeyset, each key can be programmed for one of many different uses. Examples of key as-signments include individual outside lines, individual stations (DSS), group of lines, group ofstations and one-touch speed dial keys. Using these keys eliminates the need to use diallingaccess codes.Feature keys that can have extenders to make them more specific include SPEED DIAL,SUPERVISOR, PAGE, DSS, DIRECTED PICKUP, GROUP PICKUP, BOSS, PARK, PRO-GRAMMED MESSAGE, IN AND OUT OF GROUP, FORWARD and VOICE MAIL TRANS-FER.
