FINAL

4.5.2 Earpiece mode

In Earpiece mode (Handset speaker) an artificial sid-

etone is generated. The level of the sidetone can be

adjusted and setup in the VES through parameter

fields Audio.Earp.Vol.Elementx, SideToneGain and

Audio.Heads. Elementx.SideToneGain. In Earpiece

mode it is possible to adjust the volume in the Earpiece

via API calls. In Earpiece mode the PP audio is routed

as shown in Figure 11.

4.5.3 Alert mode

The Alert mode is for generating tones and melodies

on the Speakerphone loudspeaker. In Alert mode it is

possible to adjust the volume in the speaker via API

calls. Inband tones will be affected by the volume

adjustments, since the volume control takes place after

tones are added to the signal. Figure 11 shows the

Audio flow.

4.6 CALL HANDLING

4.6.1 FP to PP call

When the FP initializes a call to a PP, a radio connec-

tion is set up to all PP applications to make it possible

for the PP application software to indicate that there is

an incoming call.

It is possible to configure the ringing indication using

broadcast to make all 64 PPs ringing.

4.6.2 PP to FP call

When the MMI software signals the PP to establish a

call, the PP opens the radio connection to the FP.

4.6.3 Intercom

Figure 15 shows the audio routing of an internal call

between PP1 and PP2. In the FP no transcoding takes

place.

4.6.4 Conference

Figure 16 shows the audio routing of a 9-party confer-

ence call.

4.6.5 Page call

The Page call is an FP functionality used to locate the

registered PPs. FP paging does not establish a normal

audio connection and is terminated when answered by

the PP.

4.7 TONE/MELODY HANDLING

The tone component handles the generation of various

tones in the device. Both tones/melodies in a PP con-

figuration are supported.

The main features of the tone component are:

• Ringer tones and melodies (7-tone polyphonic)

• Alert tones (key sound, error tones, confirmation

tones, etc.)

• Inband tones (dial tone, net-congestion tone, busy

tone, etc.)

• Single tone generation

4.8 DATE AND REAL-TIME CLOCK

The FP has a real-time clock feature, which (when acti-

vated) broadcasts the date and time of day to the PPs.

Activation of the date and real-time clock is done by

setting the date and time via the PP.

The clock supports hours, minutes and date. The date

supports leap years. Daylight saving time is not sup-

ported and must be handled by the MMI application.

The PP clock is synchronized with the FP every time a

broadcast is received. If the PP goes out-of-lock, the

PP itself calculates the clock time until the PP is again

within the range of the FP. The updated clock time can

be read locally via the MMI software.

To adjust the clock in the FP, a service connection can

be set up via commands from the PP.
