status is the same in “cold” and in “warm start”
condition.
Telephone Number Storage
In this mode the D6571E receives a word of data from
the HOST and writes it into the telephone dire ctory
under the entry number specified by HOST in a
previous command. This stored information can be
actually used as telephone number storage or for any
other purpose. The D6571E automatically returns to the
Idle mode after this command. After a certain number of
programming cycles, without Garbage Collection, the
Telephone Number directory will become full. Up to
1024 bytes can be stored in the Telephone Number
directory (128 telephone numbers, 16 digits each).
This mode is not available in case of “cold start.” Idle
status will be returned.
Non-Erasable Storage
In this mode the D6571E receives a word of data from
the HOST and writes it into the Non-Erasable Storage
under the entry number specified by HOST in a
previous command. The D6571E can store up to 800
words (1600 bytes) of data. This data can be
programmed only once and can not be erased or
modified.
This storage is not available in case of “cold start.”
General Purpose Storage (GPS)
The D6571E supports up to 16 sectors of the General
Purpose Storage. Each sector has a capacity of 3200
bytes. The number of sectors has to be defined by Host
(Storage Configuration command of the SelfTest and
Initialization mode).
After a certain number of programming cycles, without
Garbage Collection, the sector of the GPS will become
full. After Garbage Collection the sector will become
available for further programming. The D6571E allows
erasing a sector by one command (GPS command with
ERASE bit set).
Note: Garbage Collection must be executed each time
before and after writing data into GPS. Read Memory
Status command should be sent and Garbage Collection
should be executed if recommended.
This storage is not available in case of “cold start.”
Tone Generation Mode
In case of “warm start” the D6571E can generate tones
from the following tone table:

13 entries (0 - C) are preprogrammed and parameters of
these entries can not be changed. The default gain for
each tone in the table is 6 dB (code 0000) for Frequency
1 and 4 dB (code 0001) for Frequency 0.
The HOST can program 19 “user defined tones” one
time. Any desired single or double tone within the
telephony frequency bandwidth may be programmed as
described in the section “New Tone Definition”. The
HOST can instruct the D6571E to generate any of the 31
tones from the tone table.
To generate a tone, the HOST will send a Tone
Generation command with bit 11 = “0”, bits 0-4 will
indicate the TONE INDEX in the tone table and bits 5-8
will indicate the tone output gain. The D6571E will start
to generate the tone through the CODEC output and
monitor the line from the CODEC input. The D6571E will
return a status word containing information on DTMF,
CAS, and/or Call Progress Tones detected from the line.
See Line Monitor mode for a descriptions of the call
progress and DTMF tones detected. The HOST can
issue an additional, same Tone Generation command to
monitor the line, and will get a status word every frame.
The HOST can change the tone and/or the tone gain
level, on the fly, without leaving the Tone Generation
mode. In addition the Host may issue a Sensitivity
Control command to change sensitivity of any of the
detectors without interrupting the Tone Generation
mode. The status word will reflect the status of the
Tone Generation mode. Therefore line monitoring will
not be interrupted. The Tone Generation mode will end
with the IDLE command.
