D-9 Direct Outward Dialing (DOD)
General Description
This feature permits any user to gain access to the public network without the assistance of the Attendant, by dialing
an access code and receiving a second dial tone. The user may then proceed to dial the desired public network
number.
Operating Procedure
To place an outside call
1. Go off-hook; receive dial tone,
2. Dial the trunk access code (usually “9”),
3. Receive second dial tone from Central Office,
4. Dial the desired telephone number,
5. If the call is denied for any reason, reorder tone is heard.
Service Conditions
1. Outgoing connection restriction can be assigned on an individual station basis. Refer to CLASS OF
SERVICE - INDIVIDUAL [C-15].
2. TOLL RESTRICTION - 3/6-DIGIT [T-7] may be applied to DIRECT OUTWARD DIALING.
3. Various types of trunks (FX, WATS, tie, CO, etc.) can be directly accessed using this feature.
4. The trunk group access code is limited to a maximum of three digits (only when the SPEED CALLING
[S-3, 3D, 21, 23] service is required).
5. Use of the DOD feature can be denied on a per-trunk group basis when the following restrictions are active
on the originating station line.
• Fully Restricted Stations: Direct Outward Dialing attempts are routed to reorder tone when the station
is fully restricted.
• Restriction from Outgoing Calls: A station assigned this feature is denied the ability to dial-access
preselected trunk groups.
• HOT LINE [H-1]: Exchange network call completion using this feature is not permitted. The
originating station can only be routed to the ATTENDANT CONSOLE [A-3] or another station when
going off-hook.
• MISCELLANEOUS TRUNK RESTRICTION [M-3]: Preselected station lines are denied access to
preselected miscellaneous trunk groups, the station is routed to reorder tone when the station attempts
to originate a call on the trunk group.
• TOLL RESTRICTION: Level of this feature restricts unauthorized station lines' ability to complete
outgoing Central Office or Foreign Exchange calls to specified areas or office codes within an area.
• TOLL DENIAL: A station with Toll Denial is routed to reorder tone when a 0 or 1 is dialed as the first
digit after the trunk access code has been dialed.
