The intercom is able to identify these situations and solvethem by Automatic Multiple Number Dialling if one of three automatic dialling modesis enabled. Up to 6 numbers can be stored for each button.The three automatic modes (see below) recognise the continuous, busy and ringingtones, In all of these modes, automatic dialling can be disabled or the required countof cycles can be preset (1 to 9; if none of the stored numbers is answered, the wholecycle is repeated starting with the first number again) for each button separately.You can program Automatic Multiple Number Dialling for selected buttons only,retaining the others in the default mode, the selection of one of three automaticdialling modes is common.Automatic Multiple Number Dialling without ConfirmationThis mode can be used in common cases to enable the visitor to get through even ifthe called line is busy or the called subscriber is absent. Hence, the second memory ofthe button may include the secretary's number, the third memory the porter's lodgenumber, etc.This mode recognises the ringing tone and if the tone ends before the predefinedcount of rings, the intercom regards this as a successful connection, this solution is notfully reliable because detection may be hindered by noise, etc. No message is playedback in this mode.Evaluation of Situations in Audible Automatic Dialling withoutConfirmationSituation Intercom ActionBusy tone Hangs up in approximately 2 seconds and dials the nextnumber.Call or silence without previousringing toneWaits for the preset timeout (log-in time), then hangs upand dials the next number.Continuous tone (at the PBX, e.g.) Hangs up in approximately 2 seconds and dials the nextnumber.CIE-Group Ltd, www.cie-group.com 45 / 63
