The "R" button on the telephone is for use in private branch exchanges and when using T-Net functions provided by DEUTSCHENTELEKOM.
7.1 "R" button on private branch exchanges
If the telephone is connected to a private branch exchange, all the functions, such as transferring calls, automatic call back, etc., can be used. The "R" button provides access to these facilities. A private branch exchange requires a RecallTimeof"100ms"(refertoSection8.11forthesettings).Thedealerwhereyoupurchasedtheexchangecan provideinformationastowhetherthetelephonewillworkproperlywiththeexchange.
7.2RbuttonwithT-NetprovidedbyDEUTSCHENTELEKOM
The AUDIOLINE telephones support sthemost important supplementary services provided by DEUTSCHEN TELEKOM (e.g.: brokering, callwaiting, three-way conference, etc.). T-Net operates with the "Recall 300ms" setting (refer to Section 8.11 for settings). Please contact DEUTSCHEN TELEKOM with regard to enabling the T-Net functions.
7.3 Usingthediallingpause
In the case of private branch exchanges, it is necessary to dial a specific number (e.g. "9" or "0") in order to obtain the dialling tone for an outside line on the phone. When using some older private branch exchanges, it takes a little time before the dialling tone becomes audible. Especially for such private branch exchanges, it is possible to insert an automaticpauseafterthenumberfortheoutsidelinesothatthenumbercanbedialledinacontinuousprocess withouthavingtowaitforthedialllingtone.
