1.6.4 Flexible Numbering/Fixed Numbering

Description

To dial another extension user or to access PBX features, the access numbers (extension numbers or feature numbers) are required. There are three types of numbering plans:

1) Flexible Numbering (available while a dial tone is heard) 2) Flexible Numbering (available while busy, DND, or ringback tone is heard) 3) Fixed Numbering (available while dialing or talking)

1.	Flexible Numbering (available while a dial tone is heard) Extension numbers and feature numbers which are available while a dial tone is heard can be customized for easy use. The numbers must not conflict. It is also possible to use default (Pattern 1 or Pattern 2) shown in the following table:
	a) Extension Numbers: Extension numbers consist of leading numbers and additional numbers. Extension numbers (consisting of “0” through “9”) can be assigned as follows: • Numbering schemes: 1-64 • Leading number: up to three digits • Additional number: up to two digits (default: two digits) [Example] If the number "3" is programmed as a leading number for the 1st extension numbering scheme, and "XX" is programmed as the additional digits, extension numbers 300 through 399 are available. b) Feature Numbers: Up to four digits, consisting of 0-9, "", and "#" c) Other PBX Extension Numbers (Other PBX Extension Number [TIE] 01 through 16): Up to three digits, consisting of 0-9, "", and "#"

This is used for the Automatic Rerouting of VoIP Calls To Public CO Line feature.
2.	Flexible Numbering (available while a busy, DND, or ringback tone is heard) Feature numbers which are available while a busy, DND, or ringback tone is heard can be customized for easy use. The numbers should be one digit (0-9, "", or "#") and must not conflict. For a list of the default settings, refer to the following table:
	[Flexible Numbering Table (available while a busy, DND, or ringback tone is heard)] Feature Default Call Waiting/DND Override 1 or 2* Executive Busy Override 3 Message Waiting set 4 Call Monitor 5 Automatic Callback Busy 6 Alternate Calling—Ring/Voice *: To use Call Waiting/DND Override, both "1" and "2" are available by default.
3.	Fixed Numbering (available while dialing or talking) Features which are available while dialing or talking have fixed numbers, as shown in the following table:
	[Fixed Numbering Table (available while dialing or talking)] Feature Fixed Numbering Pulse to Tone Conversion Conference 3 Door Open 5

Conditions

•	The following are examples of feature number conflicts: 1 and 11, 0 and 00, 2 and 21, 10 and 101, 32 and 321, etc.
•	Feature number + Additional number (Parameter) Certain flexible feature numbers require additional digits to make the feature active. For example, to set Call Waiting, the feature number for "Call Waiting" must be followed by "1" and to cancel it, the same feature number should be followed by "0".
•	Rotary single line telephone (SLT) users cannot dial feature numbers which include "" or "#".
•	Portable station (PS) users cannot use the following features:
	– Personal Speed Dialing – OGM playback/record – S-CO Line Access – Parallel Telephone Mode set/cancel – Walking Extension – BGM set/cancel – Timed Reminder

•	Note that extensions that will have a mailbox using a VM in DPT integration must have extension numbers of 2 to 4 digits.
•	A PS can only be assigned an extension number of 4 digits or less.

1.6.6 FWD (Call Forwarding)

Description

Extensions and incoming call distribution groups can forward their calls to preset destinations. There are several different types of forwarding, and the circumstances under which the calls are forwarded for each type differ as follows:

Type Circumstance All Calls  Any time Follow Me:  When an extension user fails to set this feature before leaving the desk, this feature can be set from the destination extension. Busy  When the extension user's line is busy. No Answer  When the extension user does not answer within a preprogrammed time. Busy/No Answer  When the extension user's line is busy or the user does not answer within a preprogrammed time.

Depending on the type of incoming intercom or CO line calls, it is possible to set a different destination for each.

[Available Destinations]

Destination Availability Condition for Original Extension/Incoming Call Distribution Group Wired Extension (PT/SLT/SIP Extension/T1-OPX) Only available when FWD to extension is allowed through COS programming.* PS ICD Group PS Ring Group – Floating Extension no. for SVM – VM Group (DTMF/DPT) – External Pager (TAFAS) – DISA Only available for incoming CO line calls. Incoming intercom and doorphone calls cannot be forwarded to a DISA floating extension number. Analog/ISDN Remote Maintenance – Idle Line Access no. + Phone no. Only available when FWD to CO line is allowed through COS programming. Trunk Group Access no. + Trunk Group no. + Phone no. Extension of Another PBX (via TIE Line, Access with PBX Code) Only available when FWD to CO line is allowed through COS programming. Extension of Another PBX (via TIE Line, Access without PBX Code) –

*: If an extension user is not permitted by COS to call a certain extension (→ 1.9.14 Internal Call Block), the FWD feature will not function if that extension is set as the forwarding destination.

Conditions

[General]
•	FWD for CO Line Calls/Intercom Calls The extension user can set the FWD feature for CO line calls, for intercom calls, or for both.
•	FWD from Incoming Call Distribution Group (Group FWD) COS programming determines the incoming call distribution groups that can use this feature.
•	FWD to CO Line COS programming determines the extensions or incoming call distribution groups that can forward calls externally. The original extension's Toll Restriction and ARS still apply to the forwarded call.
•	CO Line Call Duration The duration of a CO line call can be restricted by a system timer. CO line call duration is assigned separately for calls between an extension user and an outside party, and calls between two outside parties. If the timer expires, the line will be disconnected. (→ 1.3.16 CO Line Call Limitation)
•	Multiple FWD Calls can be forwarded up to four times. The following forwarding features are counted as Multiple FWD:
	– FWD—Busy or Busy/No Answer (when the destination extension is busy), or All Calls – Idle Extension Hunting—Overflow – Intercept Routing—Busy/DND (when the destination extension is busy or in DND mode) – Incoming Call Distribution Group—Overflow
	In the above illustration, forwarding stops at extension E. However, forwarding can go farther in the following cases:
	– If a destination extension rings, and then the call is redirected to the forward destination by the FWD—No Answer or Busy/No Answer feature. – If a destination extension rings, and then the call is redirected to the intercept destination by the Intercept Routing—No Answer feature. – If a call waits in a queue of an incoming call distribution group, and then the call is redirected to the overflow destination by the Queuing Time Table. (→ 1.9.6 ICD Group Features—Queuing)
	In the above cases, the forwarding counter resets to zero, and the call can be forwarded up to four times again from the destination extension described above.
•	Boss & Secretary feature It is possible to call the original extension from the destination extension regardless of the forward setting.
•	Message Waiting While calls are forwarded, Message Waiting information is not forwarded. The Message button light turns on at the originally called extension. (→ 1.11.3 Message Waiting)
•	Idle Extension Hunting Idle Extension Hunting applies to calls forwarded to a busy extension in an idle extension hunting group.

[All Calls and Busy]
•	If the forward destination is not available to answer a call, this feature is canceled and the original destination will ring for the following type of call:
	– Doorphone call – CO line calls via the LCOT or T1 (LCOT/GCOT) cards

[No Answer and Busy/No Answer]
•	No Answer Time The number of rings before the call is forwarded is programmable for each extension.

[Follow Me]
•	This feature is only available when the original extension has set "Remote Operation by Other Extension" to "Allow" through COS programming.

1.6.7 FWD/DND Button, Group FWD Button

Description

Conditions

•	When FWD/DND buttons are set to FWD/DND Cycle Switch mode, pressing the FWD/DND button cycles the FWD/DND setting. In this mode, when intercom calls are set to be handled differently from CO line calls (forwarding type, forward destination, DND on/off):
	a) in idle mode, the light patterns of the FWD/DND—Both button (including FWD/DND button [fixed button]) and the Group FWD—Both button will indicate the setting for either CO line calls or intercom calls, but not both. b) the FWD and DND icons on a PS display reflect the settings for CO line calls only. c) pressing the FWD/DND—Both button (including FWD/DND button [fixed button]) or the Group FWD—Both button will be ignored.
•	When both the FWD and DND features are assigned simultaneously, pressing the button changes the settings as follows:
•	A FWD/DND button customized on a flexible button is always in FWD/DND Cycle Switch mode, and the mode cannot be changed.
