Categories of Learned-in Phones

The G-SPEAK range offers both voice and signalling functionality, each of which provides

its own unique feature-set and capabilities including communication, switching and

monitoring. The units are programmed via SMS command strings sent from a standard

mobile phone.

FIGURE 33.

A Voice Phone pertains specifically to the intercom functionality of the G-SPEAK system,

and is any learned-in phone with the ability to communicate by voice with the Calling

Module, but is also capable of activating any of the outputs during a call using DTMF

signalling.

Voice Phone Functionality

A clear distinction must be made between a Voice Phone and a Switch Phone.

Voice Phone

A Switch Phone is a learned-in phone that is capable of exercising some influence upon

the outputs of the controller via GSM switching and does not necessarily possess Voice

Phone Functionality, though it can be learned-in for both.

Both of these unique operating modes are discussed in more detail in the sections that

follow.

Switch Phone

The Calling Module has two Call Buttons. Each button is associated with either one Voice

Phone in the case of the G-SPEAK Classic, or two Voice Phones in the case of the

G-SPEAK Classic+, where at least one of which will need to be programmed before the

unit can be used to initiate a call (refer to the List of Commands). When a Call Button is

pressed, the Calling Module will emit either a call tone to indicate that a call is being

initiated, or three low-pitched beeps to indicate that no number is associated with that

Call Button.
