SW-H1 No. 3 Reserved

Set to "0".

SW-H1 No. 4 Busy tone continuous sound detect time

Set detecting time busy tone for 5 seconds or as is PTT.

SW-H1 No. 5 Busy tone detect continuation sound detect during
OGM

Used to detect the continuous tone of specific frequency during OGM
output.

SW-H1 No. 6 Busy tone detect continuation sound detect
(during ICM: for internal A.M.)

Used to detect the continuous tone of specific frequency during ICM
recording.

SW-H1 No. 7 Busy tone detect intermittent sound detect during
OGM

Used to detect the intermittent tone of specific frequency during OGM
output.

SW-H1 No. 8 Busy tone detect intermittent sound detect
(during ICM: for internal A.M.)

Used to detect the intermittent tone of specific frequency during ICM
recording.

SW-H2 No. 1, No. 2 Busy tone detection pulse number

Used to set detection of Busy tone intermittent sounds.

SW-H2 No. 3 Fax switching when A.M. full

If the answering machine’s memory (tape) is full and there is no
response, the machine automatically switches to Fax reception.

SW-H2 No. 4 Busy tone continuation sound detect frequency

Range of busy tone continuation sound detect frequency.

SW-H2 No. 5 ~ No. 8 Reserved

Set to "0".

SW-I1 No. 1, No. 2 ICM recording time

Used to select the incoming message recording time among
15sec/30sec/60sec/4min.

SW-I1 No. 3, No. 4 A.M. quiet time 1

Used to select four kinds of no sound time (2 sec ~ 5 sec) after
reception in the T.A.D. mode until OGM is output.

SW-I1 No. 5, No. 6 A.M. quiet time 2

Used to select four kinds of no sound time (0 sec ~ 3 sec) after OGM
output in the T.A.D. mode until ICM recording is started.

SW-I1 No. 7 Key input buzzer on/off switch (Two way recording
mode)

Used to turn ON/OFF key input buzzer in the TWO-WAY recording
mode.

SW-I1 No. 8 Reserved

Set to "0".

SW-I2 No. 1 ~ No. 5 A.M. quiet detect time

Used to set no sound time (0 sec - 32 sec) during the T.A.D. mode
operation.

SW-I2 No. 6, No. 7 Reserved

Set to "0".

SW-I2 No. 8 Reserved

Set to "0".

SW-I3 No. 1, No. 2 Reserved

Set to "0".

SW-I3 No. 3 Two way record function

If it is disable, the two way record function is not available.

SW-I3 No. 4 Tall saver function

Used to turn on the toll saver function. If it is off, the reception fre-
quency in the AM mode is identical with that in the FAX mode.

SW-I3 No. 5, No. 6 Reserved

Set to "0".

SW-I3 No. 7 BOX selection to record ICM

While the SWI2 No. 1 is off, it is possible to specify the box to record
ICM by inputting the DTMF code during OGM output or ICM record-
ing.

1-digit: Input of box number (1-3)

2-digit: Input of box number (01-03)

Note: In case of 1-digit, the DTMF code can be accepted for 4 sec-

onds from the beginning of ICM.

SW-I3 No. 8 Reserved

Set to "0".

SW-I4 No. 1 ~ No. 4 AGC maximum gain setting (Line)
(10~25dBm) (1dBm step)

The AGC Maximum Gain (parameter 58) limits the gain applied by
the AGC. Messages with average energy below the AGC Energy
Reference Level will have their average energy level increased by no
more than the AGC Maximum Gain. The AGC Maximum Gain should
be no greater than the amount of gain necessary to increase the
average energy of the message with the lowest average energy to
the AGC Energy Reference Level.

SW-I4 No. 5 ~ No. 8 AGC maximum gain setting (Mic)
(10~25dBm) (1dBm step)

SW-I5 No. 1 ~ No. 4 AGC eref access code (Line)
(-0~-30dBm) (2dBm step)

The AGC Eref Access Code (parameter 55) controls the playback
level. Any message having average speech energy above the energy
reference level has its playback level attenuated, and any message
having average speech energy below the energy reference level has
its playback level increased. If the playback level is too high (low),
then decreasing (increasing) the AGC Eref Access Code will achieve
the desired level.
