1.5 Making Call Features

1.5.1 Intercom Call Features

1.5.1.1 Intercom Call

Description

Conditions

•	Extension Number/Name Assignment Extension numbers ( Extension Number [009]) and names ( Extension Name [604], Extension Name in Cyrillic [616]) can be assigned to all extensions. During intercom calls, the number and name of the other extension are shown on the displays of proprietary telephones (PTs).
•	DSS Button It is possible to call another extension simply by pressing the corresponding Direct Station Selection (DSS) button ( DSS Off-hook Mode [126]). A flexible CO/DSS/MESSAGE button can be customised as a DSS button. The DSS buttons on a DSS Console can also be used.
•	Alternate Receiving—Ring/Voice A PT user can select to receive intercom calls by ring tone or by voice, through personal programming (Alternate Receiving—Ring/Voice). If a user selects voice-calling, the calling party can talk to the user immediately after hearing a confirmation tone.
•	Alternate Calling—Ring/Voice A caller can change the called party's preset call receiving method (ring tone or voice). By doing so, ring-calling is switched to voice-calling, or vice versa, at the called party. This setting is active for the current call only, after which it reverts to the called party's previous setting.
•	The extension ring tone pattern for incoming intercom calls can be selected through system programming ( Extension Ring Tone Pattern [115]). The ringback tone pattern for outgoing intercom calls and for incoming outside (CO) line calls can also be selected through system programming ( Ringback Tone Pattern [128]).
•	Tone after Dialling After dialling an extension number, a user will hear one of the following:
	Type Description Ringback Tone Indicates the call is being received at the called party's extension. Confirmation Tone Indicates the called party has set voice-calling. Busy Tone Indicates the called party's extension is busy. DND Tone Indicates the called party has set Do Not Disturb (DND).

1.5.2 Outside (CO) Line Call Features

1.5.2.1 Outside (CO) Line Call Features—OVERVIEW

Description

1.5.2.2 Emergency Call

Description

An extension user can dial preprogrammed emergency numbers ( Emergency Number [309]) after seizing an outside (CO) line regardless of the restrictions imposed on the extension.

Conditions

•	If the PBX is installed behind an existing host PBX, an extension user must dial the Host PBX Access code after the Outside (CO) Line Access number.
•	This feature will function even when:
	– In Account Code—Verify-All/Verify-Toll/Forced mode ( 1.5.2.3 Account Code Entry) – Restricted by the current class of service (COS) ( 1.8.1 Toll Restriction (TRS)) – In Extension Lock ( 1.8.3 Extension Lock)

1.5.2.3 Account Code Entry

Description

An account code is used to identify outgoing outside (CO) line calls for accounting and billing purposes. Account codes are appended to SMDR call records ( 1.20.1 Station Message Detail Recording (SMDR)), and have several uses. For example, a firm can use an account code for each client to determine which calls were made for which client, and can submit a bill to the client according to the client's account code as shown on the SMDR call record. There are 4 methods of entering account codes, explained below. One method is assigned to each extension through system programming ( Account Code Mode [605]).

Mode Description Option An extension user can (but is not required to) enter a 4-digit account code during a conversation or within 30 seconds after a conversation ends when a record is needed. Forced An extension user must always enter a 4-digit account code within 5 seconds after seizing an outside (CO) line. This method ensures that extension users will not forget to enter account codes. Verify-All An extension user must always enter a preprogrammed account code ( Account Code [310]) within 5 seconds after seizing an outside (CO) line. If the entered code does not match any preprogrammed code, the user will hear a reorder tone. Verify-Toll An extension user can enter a preprogrammed account code ( Account Code [310]) within 5 seconds after seizing an outside (CO) line to override TRS ( 1.8.2 Toll Restriction (TRS) Override by Account Code). Classes of service (COSs) 3 through 5 will be changed temporarily to COS 2. COSs 1 and 2 will not be affected. If the entered account code is also registered as an extension password, the extension password feature will be given priority. The COS of the corresponding extension will be applied.

Conditions

•	An account code can be stored in Memory Dialling (One-touch Dialling, Hot Line, Speed Dialling—System/Personal, Call Forwarding (FWD) to Outside (CO) Line, etc.). In this case, the Account Code feature number and specified account code must be entered after the Outside (CO) Line Access number.
•	An extension user does not need to enter an account code for incoming outside (CO) line calls.
•	Even in Forced/Verify-All/Verify-Toll mode, emergency calls can be made without an account code ( 1.5.2.2 Emergency Call).

1.5.2.4 Dial Type Selection

Description

The dialling mode can be selected for each outside (CO) line through system programming ( Dial Mode [401]) regardless of the originating extension (dependent on the contract with the telephone company).

Mode Description DTMF (Dual Tone Multi-Frequency) Numbers dialled by an extension user are transmitted to the outside (CO) line using tones. If this PBX is installed behind an existing host PBX, select this mode as necessary. Pulse (Rotary) Numbers dialled by an extension user are transmitted to the outside (CO) line using pulses. Call Blocking If your telephone company or a host PBX can receive both DTMF and Pulse signals but the contract specifies Pulse lines, select this mode. When dialling with a touch-tone telephone, only Pulse signals will be sent to the telephone company.

Conditions

•	Automatic Configuration for Outside (CO) Line Type The dialling mode of connected outside (CO) lines is automatically assigned after restarting the PBX using the System Clear Switch or through system programming ( System Data Clear [999]). No system programming in Dial Mode [401] and Pulse Speed [402] is required unless the dialling mode of the connected outside (CO) lines is Call Blocking. If your telephone company can receive both DTMF and Pulse signals, the PBX selects an outside (CO) line type according to the following priority: DTMF Pulse (High) Pulse (Low)
•	Pulse to Tone Conversion It is possible for an extension user to temporarily switch from Pulse mode to DTMF mode in order to access special services such as computer-accessed long-distance calling or voice mail services. To switch to DTMF mode, wait for a preprogrammed time period after the outside (CO) line is connected, or press the "#" key. This feature functions only on outside (CO) lines set to "Pulse" or "Call Block" mode ( Dial Mode [401]). DTMF mode cannot be changed to Pulse mode.
•	The pulse rate for outside (CO) lines that have been set to "Pulse" or "Call Block" mode ( Pulse Speed [402]) should be selected depending on your telephone company. There are 2 pulse rates: Low (10 pps) and High (20 pps).
•	It is possible to assign the minimum duration of the DTMF signal sent to outside (CO) lines that have been set to "DTMF" mode ( DTMF Time [210]).
•	It is programmable whether DTMF dialling is sent to the telephone company when an extension user redials after changing from Pulse mode to DTMF mode by pressing the "#" key ( Redialling after Pulse to Tone Conversion [119]).

1.5.2.5 Reverse Circuit

Description

The PBX can detect the reverse signal sent from the telephone company when an extension user tries to make an outside (CO) line call. This detects the start (the called party goes off-hook) and end (the called party goes on-hook) of an outgoing outside (CO) line call. The duration of the call can be verified with SMDR using this feature ( 1.20.1 Station Message Detail Recording (SMDR)).

This feature is also known as Polarity Reverse Detection.

Conditions

•	If Reverse Signal Detection is enabled for an outside (CO) line ( Polarity Reverse Detection [424]), the PBX will automatically start the timer ( Call Duration Counter Start [204]) immediately after the outside party answers the call.

1.5.2.6 Pause Insertion

Description

A dialling pause of a preprogrammed length can be inserted manually or automatically when dialling.

Manual Pause Insertion: A pause can be manually inserted by pressing the PAUSE button.

Automatic Pause Insertion: A pause will be automatically inserted after the user dials any one of the following numbers:

a) Outside (CO) Line Access number b) Automatic Pause Insertion code c) Host PBX Access code ( 1.5.2.7 Host PBX Access Code (Access Code to the Telephone Company from a Host PBX))

Conditions

•	The pause length is programmable for each outside (CO) line ( Pause Time [417]).
•	When a dialled telephone number matches one of the Automatic Pause Insertion codes assigned through system programming ( Automatic Pause Insertion Code [311]), a pause will be automatically inserted after the code. This is particularly convenient if a second dial tone is sent from your telephone company.

1.5.2.7 Host PBX Access Code (Access Code to the Telephone Company from a Host PBX)

Description

This PBX can be installed behind an existing host PBX. This is performed by connecting extension jacks of the host PBX to outside (CO) line ports of this PBX. A Host PBX Access code, assigned through system programming ( Host PBX Access Code [403]), is required to access the telephone company from the host PBX. The Outside (CO) Line Access number (9/0  , or 81 through 88) of the host PBX should be stored as a Host PBX Access code for each outside (CO) line of this PBX. A pause of a preprogrammed length ( Pause Time [417]) will be automatically inserted after the user-dialled Host PBX Access code.

[Example]

Note In this example, "0" should be assigned as the Host PBX Access code for outside (CO) line 1 of this PBX.

Conditions

•	Access to the host PBX during a conversation is also possible ( 1.10.7 External Feature Access (EFA)).
•	TRS TRS checks only the dialled telephone number, excluding the Host PBX Access code, when accessing the telephone company through the host PBX ( 1.8.1 Toll Restriction (TRS)).
•	SMDR The Host PBX Access code can be logged by SMDR along with the dialled number when accessing the telephone company through the host PBX ( 1.20.1 Station Message Detail Recording (SMDR)).

1.5.3 Seizing a Line Features

1.5.3.1 Seizing a Line Features—OVERVIEW

Description

1.5.3.2 Line Preference—Outgoing

Description

Through personal programming, a proprietary telephone (PT) user can select the preferred method of seizing a line (Line Preference—Outgoing) to be used each time the user goes off-hook.

Method Description Idle Line  When a user goes off-hook, an idle outside (CO) line is selected automatically from among the assigned outside (CO) lines ( Automatic Designated Line Access [419]). No Line  When a user goes off-hook, no line is selected. In order to make a call, the user must select the desired line manually. Prime Line  When a user goes off-hook, the preset line is selected automatically.

Conditions

•	A flexible CO button should be assigned as an Outside (CO) Line Access button (Single-CO [S-CO], Group-CO [G-CO], or Other-CO [O-CO]) before selecting a line preference.
•	Setting a new line preference clears the previous line preference.
•	Line Preference Override A user can override the preset line preference temporarily by pressing the desired Outside (CO) Line Access button before going off-hook.
•	System programming determines the extension users that can make outside (CO) line calls in each time service mode ( Flexible Outward Dialling—Day/Night/Lunch [405-407]).
•	It is possible to specify which outside (CO) lines are connected to the PBX ( CO Line Connection [400]). This prevents extension users from trying to select or making calls using outside (CO) lines that are not connected.

1.5.3.3 Outside (CO) Line Access

Description

There are 3 methods of accessing an outside (CO) line.

Method Description Operation Automatic Line Access (Local Access)  Selects an idle outside (CO) line automatically from the assigned outside (CO) lines ( Automatic Designated Line Access [419]). If Idle Line Preference ( 1.5.3.2 Line Preference—Outgoing) is set on the extension through personal programming, the user can access an idle line simply by going off-hook. Dial the Automatic Line Access number (9/0)* ( Automatic Line Access [121]). Note * For New Zealand, the Automatic Line Access number may be either 1 or 9. Outside (CO) Line Group Access  Selects an idle outside (CO) line from the corresponding outside (CO) line group. Dial the Outside (CO) Line Group Access number and an outside (CO) line group number, or press a Group-CO (G-CO) button. S-CO Line Access  Selects the desired outside (CO) line directly. Press the Single-CO (S-CO) button.

Line Access Using the Other-CO (O-CO) Button To select an idle outside (CO) line from among the outside (CO) lines that are not assigned to S-CO or G-CO buttons, the proprietary telephone (PT) user can press the O-CO button.

Conditions

•	The PBX waits for a preprogrammed length of time ( Dialling Start Time [206]) after seizing an outside (CO) line before dialling.
•	Button Assignment
	A flexible CO button can be customised as an S-CO, G-CO, or O-CO button as follows: Type Assignable parameter Single-CO (S-CO) A specified outside (CO) line is assigned (Default: CO 1–CO 8). Group-CO (G-CO) An outside (CO) line group is assigned ( CO Line Group Number [404]). Other-CO (O-CO) Outside (CO) lines that are not assigned to S-CO or G-CO buttons are assigned. The same outside (CO) line group can be assigned to more than one G-CO button on the same PT. The same outside (CO) line can be assigned to an S-CO button and a G-CO button. Dialling the Outside (CO) Line Access number selects a CO button according to the following priority: S-CO G-CO O-CO Once a flexible CO button is assigned as an Outside (CO) Line Access button, it indicates line status with a variety of light patterns ( 1.18.3 LED Indication).
•	Direct Outside (CO) Line Access If a PT user is on-hook when pressing an idle CO button, the PT automatically enables hands-free operation mode. The user can dial without lifting the handset or pressing the SP-PHONE or MONITOR button.
•	Outside (CO) Line Hunting Order for Automatic Line Access The outside (CO) line hunting sequence (from highest-numbered outside (CO) line, or in rotation) for Automatic Line Access can be determined through system programming ( Automatic Rotation for CO Line Access [122]).
•	System programming determines the extension users that can make outside (CO) line calls in each time service mode ( Flexible Outward Dialling—Day/Night/Lunch [405-407]).
•	It is possible to specify which outside (CO) lines are connected to the PBX ( CO Line Connection [400]). This prevents extension users from trying to select or making calls using outside (CO) lines that are not connected.
