Versatile speech/dialler/ringer with
music-on-hold
TEA1069; TEA1069A
The STD contains the states (rectangles in the figure) and
state transitions (arrows) of the set. The upper arrow in the
figure pointing to the standby state means that the set is
initially in the standby state. When for instance an
incoming call is detected, the set enters the ringer state,
waiting for a reaction of the user. If the user answers the
call on a handset, the set enters the on-line state.
The TEA1069 and TEA1069A have 3 basic states:
Standby state
Ringer state
On-line state.
Each state with its own functional requirements is
described in the following sections.
S
TANDBY STATE
In standby state the TEA1069 and TEA1069A are inactive.
The current drawn is for memory retention and depends on
the loads of the inputs/outputs of the dialler. In this state
output DP/FL is HIGH so that the line is disconnected.
The ICs leave the standby state if:
The set goes off-hook (lift handset or press [HOOK])
A ringer-signal is available on the line.
The ICs go to the standby state if:
The set goes on-hook
(handset on the cradle or press [HOOK])
A line-break occurs for at least the reset delay time (t
rd
)
The ringer-signal becomes invalid.
R
INGER STATE
If the set is in standby mode, a ringer signal can be
received from the line. After evaluating the incoming ringer
signal (and ringer signal is valid), the TEA1069 and
TEA1069A start a melody via the TONE output ringer
hardware, and stops this melody if the ringer signal is not
valid any more. After going off-hook, the ringer signal stops
and the set is in conversation (on-line) state.
During a ringer burst the ringer volume can be changed
according to Fig.24 and melodies can be changed
according to Table 7.

LINE STATE
In this paragraph all the actions of the TEA1069 and
TEA1069A during on-line state are described. The on-line
mode starts with making output DP/FL LOW, which makes
line current flow possible. The on-line state contains a
number of sub-states (see Fig.22):
Conversation state
Dialling state
Memory recall state
Program state.
