restricted
00 The data can be changed when analog send (G3 Fax/Telephone) by the ISDN
line needs to be restricted. By changing the data, the ISDN line can be open
only to be used for digital send or digital send or analog receive.
CE
57 163*** Restrictions on sending G4CH0(Channel
0 communication guard)
0: Send not restricted 1:Send
restricted
00 The data can be changed when G4 mode send by the ISDN line needs to be
restricted. By changing the data, the ISDN line can be restricted only to be
used for analog send operation.
CE
57 164 Restrictions on sending
ISDN_CSDN0:G4 restriction
(B1ch)(network guard)
0: Send not restricted 1:Send
restricted
00 The data can be changed when G4 mode send to the ISDN line via B1ch
needs to be restricted. By changing the data, the traffic volume of G4 send
operation via ISDN line can be restricted.
CE
57 165 Restrictions on sending
ISDN_CSDN1:G4 restriction
(B2ch)(network guard)
0: Send not restricted 1:Send
restricted
00 The data can be changed when G4 mode send to the ISDN line via B2ch
needs to be restricted. By changing the data, the traffic volume of G4 send
operation via ISDN line can be restricted.
CE
57 180 ISDN dial tone 0:tone off 1:400Hz consecutive tone
2:400Hz On(260ms)/Off(260ms)
3:400Hz On(180ms)/Off(260ms)
01 The data specifies the mock dial tone type to be informed to the operator by
Main unit when the handset is lifted up and the ISDN line has been captured.
CE
57 184 DTMF Signal Amplification Gain 0 to -28 dB m 16=-16
dB m
This data specifies a send power level for a selected pushbutton tone signal
(DTMF) when an ISDN line is connected.
CE
57 190 Closed-Area Communication 0:Disable 1:Enable 00
57 201 Reception Mode 0: TEL/FAX mode (TEL Priority)
1: FAX mode (FAX Only)
01 Set the Reception Mode
57 202 Ring detection time at FAX 0 to 255 sec. (1step=1 sec.) 00 Set up time to switch to Fax when transmission is received. Bell rings at the
handset/separate telephone for the specified time when the terminal receieves
a call.
User
57 203 Restriction of change of the ring
detection time by user
0: Do not restrict 1: Restrict 00 The data to restrict the change of 57-202 ring detection time at FAX.
57 204 0 to 255 sec. 1step=1 sec. 21 Auto Answering Time in TEL/FAX Auto Switching Mode (TEL Priority)
57 210 Direct Mail refection 0=Off 1=On 00 The terminal refers the last 4 digits of all numbers stored in the speed dial
directory to the last 4 digits of the ID codes sent from the remote terminal and
receives only the numbers that match. The feature can be switched on and
off. “Space” will be ignored when the reference is made.
CE
57 260 CNG Signal (Dial Tone) Detection Time. 0 to 25500(ms) 1step=100ms 55 This data is used in TEL Priority mode. If no CNG signal is detected within this
time, the auto answering function (external telephone) is called.
57 270 CED Send 0: Do not send 1: Send 01
57 271 CED Send for Manual Reception 0: Do not send 1: Send 01
57 272 CED Send Frequency 0:2100Hz 1:1650Hz 2:1100Hz 00 This data changes the frequency of a CED. If an eco suppressor causes a
fault in international communication, change the frequency to other than 2100
Hz. However, be careful when changing the frequency because some
transmitters may monitor only CED signals of 2100 Hz
