							1.1 General Features
62 Feature Manual
Conditions
WARNING
There is a risk that fraudulent telephone calls will be made using the Outside-to-Outside (CO-to-CO) 
Line Call feature of DISA.
The cost of such calls will be billed to the owner/renter of the PBX.
To protect the PBX from this kind of fraudulent use, we strongly recommend:
a)Enabling DISA security (Trunk Security or All Security).
b)Maintaining the secrecy of passwords.
c)Selecting passwords that are complex and random, so that they cannot be easily guessed.
d)Changing passwords regularly.
 The maximum recording time of each message is 3 minutes.
 The preinstalled DISA OGM card can play only one message at a time and the total recording time of 
the PBX for DISA OGMs is 3 minutes. When an optional message expansion card for DISA OGMs is 
added, up to 2 messages can be played simultaneously for callers, and the total recording time of the 
PBX is increased to 6 minutes.
 To use this feature, DISA must be selected as the distribution method for the desired outside (CO) line 
port (  [414-416] CO Line Mode—Day/Night/Lunch).
DISA Delayed Answer Time
It is possible to set the DISA Delayed Answer time (  [504] DISA Delayed Answer Time) so that the 
caller will hear a ringback tone for a preprogrammed length of time before hearing a DISA OGM or a 
short beep.
Call Forwarding (FWD) to Outside (CO) Line
When a DISA call is forwarded to an outside party, the caller is not required to enter a DISA security 
code regardless of the security mode.
SMDR
The following are logged by SMDR for DISA calls (  1.1.112 Station Message Detail Recording 
(SMDR)):
– The destination of the DISA call
– DISA security code status 
Call Deny
System programming determines which extensions can receive DISA calls (  [516] DISA Incoming 
Assignment). If a DISA call is received at an extension that has Call Deny set, the caller will hear a 
reorder tone and the call will be disconnected automatically. If a DISA call is received by a DISA ring 
group, this program does not function for extensions in that DISA ring group and these extensions will 
still ring.
Cyclic Tone Detection
It is possible to select the number of times a cyclic tone must be detected while the DISA OGM is sent 
(  [513] Cyclic Tone Detection). Cyclic Tone Detection can be used to disconnect an outside-to-
outside (CO-to-CO) line call via DISA.
Fax Connection
System programming determines the extensions that are able to receive fax data when the PBX 
receives a fax (CNG) tone via the DISA feature (  [503] FAX Connection). The preprogrammed 
extension will automatically have the Data Line Security feature set (  1.1.37 Data Line Security). 
Fax Tone Detection
It is possible to select the number of times the fax (CNG) tone must be detected while the DISA OGM 
is sent before the PBX recognizes the incoming signal as fax data (  [514] FAX Tone Detection). If the 
DISA OGM is short (0–5 s), in some cases the fax (CNG) tone may not be detected. In this case, it is 
recommended to set the length of time the PBX continues to search for a fax (CNG) tone after 
completing a DISA OGM to 10 s or 15 s through system programming (  [505] DISA Wait Time  
						

							1.1 General Features
Feature Manual 63
after OGM). If the assigned DISA OGM has not been recorded, it is recommended to set the length of 
time to 6 s or 9 s through system programming (  [515] Intercept Time for Internal DISA).
 It is programmable whether a ringback tone (  [128] Ringback Tone Pattern) or Music on Hold (  
[111] Music on Hold) is sent to the caller when a DISA call is received (  [531] DISA Ringback Tone).

Description
A Direct Inward System Access (DISA) ring group is a specific extension group that receives DISA calls 
directed to the group. All extensions in the DISA ring group assigned as an Automated Attendant (AA) 
destination (  [501] DISA Built-in AA) ring simultaneously.
Conditions
 To use this feature, DISA must be selected as the distribution method for the desired outside (CO) line 
port (  [414-416] CO Line Mode—Day/Night/Lunch), and DISA AA service must be assigned as the 
destination of incoming outside (CO) line calls via the DISA feature (  [500] DISA Incoming Call Dial 
Mode).
 The Log-in or Log-out status can be set for each extension (  1.1.80 Log-in/Log-out). The last member 
of a group cannot log out.

Multilingual Display
Each extension can select its display language through system programming (  [615] LCD 
Language). The selected language is shown on the display during operation and personal 
programming, but not during system programming.
Display Contrast
The display contrast can be adjusted with the Navigator key or the CONTRAST selector. This is 
available only for PTs.
Ringer Volume
The volume of the ringer can be adjusted with the RINGER Volume selector.
Self-extension Number
A display PT user can confirm his or her own jack number and extension number on the display. Every 
time the   key is pressed, the display switches between date (month, day) and time, date (month, 
day, year, day of the week), and extension number (and extension name if stored).
Date and Time Set
The current date and time are set through system programming (  [000] Date & Time) or the operator/
manager service features. The time format shown on the display PTs while on-hook, 12 h or 24 h, 
can also be selected through system programming (  [010] LCD Time Display).
 Characters (name) or digits (telephone number) exceeding the maximum length of the display are not 
displayed.
However, even if the information is not displayed properly, the received information is not altered. When 
the information displayed by pressing specific buttons (One-touch Dialing, REDIAL, Save) while on-
hook exceeds 17 characters, the & mark will be shown on the right side of the display.

1.1.44 Do Not Disturb (DND)
Description
Extension users can use this feature to prevent calls from ringing at their extension. The calling extension 
will hear a Do Not Disturb (DND) tone.
Conditions
DND Override
An extension in DND mode can be called by extensions that are allowed to override DND through 
system programming (  [609] DND Override).
FWD/DND Button
If a proprietary telephone (PT) does not have an FWD/DND button, a flexible CO button can be 
customized as an FWD/DND button.
[Button Status]
The FWD/DND button shows the current status as follows:
 Setting a new FWD mode, such as All Calls or Busy/No Answer, or the DND feature, clears the status 
of the previous FWD mode or DND feature.
 This feature does not apply to calls from Hold Recall, Camp-on Recall, and Timed Reminder.
 Calls from outside (CO) lines programmed as Normal or DIL (  [414-416] CO Line Mode—Day/
Night/Lunch) can be received at a users extension, but the telephone will not ring. The corresponding 
CO button will flash when an outside (CO) line call is received, and the user can answer the call by 
pressing this button.

Description
Extension users can choose how their telephones receive doorphone calls, by selecting to hear ringing, a 
chime, or both, provided a doorbell/door chime connected to a door opener is connected to the PBX. They 
can recognize which doorphone is ringing by selecting a different doorphone chime pattern for each 
doorphone.
[Programming Example]
In order for an extension connected to extension jack 01 (extension 101) to be able to receive a doorphone 
call from a doorbell/door chime connected to Relay 4, program as follows: 
						

							1.1 General Features
70 Feature Manual
In this example
When a visitor presses the Call button of Doorphone 2:
– A doorbell/door chime, connected to Relay 4, chimes with Pattern 2.
– Because Doorphone Ring/Chime is set to Chime, extension 101 does not ring.
– The extension user who is allowed to receive a call from Doorphone 2 can answer the doorphone 
call by going off-hook within a preprogrammed time period (  [708] Doorphone Ring Time). If the 
user is allowed to unlock the door (  [703-705] Door Opener—Day/Night/Lunch), he or she can 
then unlock the door by entering the Door Open feature number.
– If the called extension is busy and has set Call Waiting, the extension user hears a call waiting tone 
and the call information flashes on the display.
Conditions
Hardware Requirement: A user-supplied doorbell/door chime connected to each door opener.
