CONVERSATION
Handset state.
The conversation states are shown in Fig.23.
Hands-free state.
In hands-free mode output HF becomes HIGH which
activates a TEA1093/1094 hands-free IC. This state can
be reached from standby state and from the handset
state as follows:
– the [HOOK] key is pressed during standby mode
– the [HOOK] key is pressed during handset state is
lifted, then when the handset is put on the cradle the
set stays in the hands-free mode.
The set leaves the hands-free mode and output HF
becomes LOW when:
– the [HOOK] key is pressed and the handset is on the
cradle, the set goes to the standby mode
– the [HOOK] key is pressed and the handset is lifted,
the set goes to the handset state.
The volume on the loudspeaker or buzzer, in hands-free
and ringer mode, can be controlled in four levels using
the [VOL+] and [VOL
] keys.
The hands-free volume can be changed according to
Fig.24.
Hold state.
The hold state is entered when the [HOLD/MUTE] key is
pressed (diode HMS =
on
). This state can be entered
either from handset state or from hands-free state. Upon
entering this state outputs HF and MUTE become LOW.
In hold state a music-on-hold melody is generated by
output TONE. Pin MOH/DMO is HIGH (diode
GOS =
off
) during this state. This signal can be used to
adjust the volume of the TONE pin. Since MUTE is LOW
the TONE output is transmitted to the telephone line.
As long as the TEA1069 and TEA1069A are in this state
the HOLD input pin is tested.
The set leaves the hold state when:
– [HOLD/MUTE] is pressed, the set returns to either the
handset or hands-free state
– the HOLD input becomes LOW, now the TEA1069
and TEA1069A return to the standby state.
