1.9.1 ICD GROUP FEATURES

Description

An incoming call distribution group is a group of extensions programmed through system programming.

→ 2.10.13 [3-5-1] Incoming Call Distribution Group—Member List → [620] Incoming Call Distribution Group Member

An incoming call distribution group receives calls directed to the group. Each incoming call distribution group has a floating extension number (default: 6 + two-digit group number). Incoming calls directed to an incoming call distribution group are distributed to the member extensions in the group using a distribution method. When a preprogrammed number of extensions in the group are busy, the incoming calls can wait in a queue. Each incoming call distribution group and member extensions can be programmed as desired to handle incoming calls. Calls to the group can be monitored by an extension assigned as a supervisor.

1.9.2 ICD Group Features—Group Call Distribution

Description

Incoming calls directed to an incoming call distribution group are distributed to the member extensions using the selected distribution method until a preprogrammed number of extensions (agents) are busy with calls. When incoming calls exceed the number of available extensions, calls enter a queue (→ 1.9.6 ICD Group Features—Queuing).

1.	Distribution Method One of the three distribution methods below can be assigned to each incoming call distribution group.
	Distribution Method Description   Uniform Call Distribution (UCD) Calls are distributed evenly to a different extension each time a call is received. Extensions are hunted in a circular way in the preprogrammed order for the group, starting at the extension after the extension that received the last call. Depending on system programming, calls can be directed to the longest idle extension. This is known as Automatic Call Distribution (ACD).   Priority Hunting An idle extension is searched for using the preprogrammed order for the group.  Ring All extensions in the group ring simultaneously.  Delayed Ringing: Delayed ringing or no ringing can be programmed for each extension in the group. The call can be answered by pressing the flashing button even if no ring or a delayed time is set.
2.	Call Waiting for Incoming Call Distribution Group (Group Call Waiting) When there are no available extensions in an incoming call distribution group, the group members can receive the Call Waiting tone. To use this feature:
	• Select the Group Call Waiting mode through system programming. This determines the distribution method for waiting calls. • Member extensions must assign the Call Waiting mode individually, or they will not be notified. (→ 1.3.10 CALL WAITING FEATURES)
	[How the Group Call Waiting Feature Activates] *: Incoming calls enter the queue immediately. Member extensions do not receive the Call Waiting tone. [Example] [ICD Group Button for Group Call Waiting] The way that the Group Call Waiting feature works depends on the Group Call Waiting Distribution method as follows: a) Ring: The Group Call Waiting feature activates for all busy member extensions (even when the extensions do not have ICD Group buttons) simultaneously for only one incoming call—additional calls will wait in a queue. b) UCD/Priority Hunting: The Group Call Waiting feature activates on an idle ICD Group button located on busy member extensions in a certain order. (This order depends on the type: UCD or Priority Hunting.) Calls will arrive at idle buttons until all ICD Group buttons are occupied—additional calls will wait in a queue. Note In method b), if an extension has one or more ICD Group buttons for an incoming call distribution group and all the ICD Group buttons on the extension are occupied, the Group Call Waiting feature for the group will not work at the extension.
3.	No Reply Redirection (UCD or Priority Hunting Method) If a call received at a member extension is not answered within a preprogrammed time period (No Answer time), the call will be redirected to the next member extension. If there is no idle group member, the call queues at the target extension until a group member becomes available.

1.9.3 ICD Group Features—Log-in/Log-out

Description

Members of an incoming call distribution group can join (Log-in) or leave (Log-out) the group manually. They can leave the group temporarily when they are away from their desks, to prevent calls being sent to their extensions. They can return to the group when they are ready to answer calls.

Wrap-up: While logged in, a member extension can have a preprogrammed time period automatically for refusing calls after completing the previous call (Wrap-up time). While the Wrap-up timer is active, calls to all incoming call distribution groups to which the extension belongs will skip the extension so that the extension user can perform necessary tasks such as reporting on the previous call. Wrap-up mode can also be activated manually (Not Ready) by pressing the Wrap-up button.

[Log-in/Log-out and Wrap-up Status Example]

Conditions

•	It is programmable whether the last remaining logged-in extension can log out.
•	Log-in/Log-out Button A flexible button can be customized as the Log-in/Log-out button with the following parameters:
	Parameter Usage Light Pattern Red on Off No parameter Used with an ICD Group button, or with the floating extension number of an incoming call distribution group, or with (All). — — Floating extension number of a specified incoming call distribution group Used to log in to or out of the specified incoming call distribution group. Log-out Status Log-in Status (All) Used to log in to or out of all incoming call distribution groups to which the extension user belongs. After Log-out Operation After Log-in Operation
•	If an ICD Group button is assigned, it also shows the log-in/log-out status of the corresponding group. The light pattern is the same as the Log-in/Log-out button that includes the group number.
•	Wrap-up Timer
	– Two wrap-up timers can be programmed, an ICD Group member wrap-up timer and an extension wrap-up timer. System programming selects which timer is used. When the ICD Group member wrap-up timer is selected, the timer is only activated after calls to the extension through an ICD Group. When the extension wrap-up timer is selected, the timer is activated after all calls to or from the extension, including a retrieved call on hold. – Only calls from ICD Groups cannot be received during the wrap-up time. Other calls are received as normal. – The wrap-up timer does not work for SIP extensions or PS Ring Groups.
•	Wrap-up Button A flexible button can be customized as the Wrap-up button. It shows the current status as follows:
	Light pattern Status Slow red flashing Wrap-up Red on Not Ready Off Ready (Wrap-up mode cancel)
•	When a PS in Wireless XDP Parallel Mode completes a call, neither the PS nor its wired telephone can have Wrap-up time. (→ 1.20.5 Wireless XDP Parallel Mode)
•	Automatic Log-out A member extension may be logged out automatically, if the Unanswered time expires a preprogrammed number of times consecutively. The number of consecutive unanswered calls can be assigned for each incoming call distribution group. If the extension is a member of more than one incoming call distribution group, the unanswered number is counted across all corresponding incoming call distribution groups. It is possible to return to log-in mode manually. The Automatic Log-out feature does not work for extensions in an incoming call distribution group using the Ring distribution method (→ 1.9.2 ICD Group Features—Group Call Distribution).
•	Log-in/Log-out Monitor The supervisor extension can monitor and control the log-in/log-out status of the incoming call distribution group members. (→ 1.9.7 ICD Group Features—Supervisory)
•	Log-in/Log-out Information on SMDR Log-in/Log-out information can be printed out on SMDR. (→ 1.16.3 SMDR (Station Message Detail Recording))

1.9.4 ICD Group Features—Outside Destinations

Description

Up to 4 outside parties or destinations at another PBX can be assigned as members of an Incoming Call Distribution (ICD) Group, using the following method: A virtual PS is registered as a member of the ICD Group. Then, the telephone number of the outside destination is specified as the FWD—All Calls destination. Calls to the ICD Group will also ring at the outside destination as if that destination were an extension within the PBX. This is useful in situations such as the following:

• An extension user can have his PT and multiple cellular phones ring together for calls. • An employee who is not in the office, but is still available to answer calls, can receive calls to an ICD Group.

Cellular Phone XDP Parallel

The extension registered first in an ICD Group can program the Forward settings for CO line calls to up to 4 virtual PSs through PT programming. Using this feature, an extension user can assign his cellular phone to ring with his PT, so that he can easily receive CO line calls even when not at his desk.

1.9.5 ICD Group Features—Overflow

Description

When waiting calls exceed the waiting queue capacity, they may be redirected to a preprogrammed destination or a busy tone may be sent to the callers by the following features:

1) Intercept Routing—Overflow in an Incoming Call Distribution Group 2) Busy on Busy

1.	Intercept Routing—Overflow in an Incoming Call Distribution Group
	Intercept Routing—Overflow in an Incoming Call Distribution Group works in one of following conditions: a) There is no space in the waiting queue. b) The Queuing Time Table is not assigned and there are no extensions logged in. c) An Overflow command is assigned to the Queuing Time Table. d) The Overflow time expires. e) Manual Queue Redirection is performed. [Available Destination] The overflow destinations can be assigned for each incoming call distribution group and each time mode (day/lunch/break/night) (→1.17.5 Time Service). The destination can be assigned as follows, depending on the above conditions. • For a) and b): → 2.10.12 [3-5-1] Incoming Call Distribution Group—Group Settings—Overflow Queuing Busy—Queuing Busy—Destination-Day, Lunch, Break, Night → [627] Destination When All Busy • For c), d), and e): → 2.10.12 [3-5-1] Incoming Call Distribution Group—Group Settings—Overflow No Answer—Time out & Manual Queue Redirection—Destination-Day, Lunch, Break, Night → [625] Destination for Overflow Time Expiration Destination Availability Wired Extension (PT/SLT/SIP Extension/T1-OPX) PS ICD Group PS Ring Group Floating Extension no. for SVM VM Group (DTMF/DPT) External Pager (TAFAS) DISA Analog/ISDN Remote Maintenance Idle Line Access no. + Phone no.

1.9.6 ICD Group Features—Queuing

Description

When a preprogrammed number of extensions in an incoming call distribution group are busy, additional incoming calls can wait in a queue. The number of calls which can wait in the queue is programmable. While calls are waiting in the queue, the calls are handled by the Queuing Time Table, which can be assigned for each time mode (day/lunch/break/night) (→ 1.17.5 Time Service). This PBX supports a specified number of Queuing Time Tables which each have a specified number of sequences (specific commands which are performed when a caller enters a queue). The following commands can be assigned to each sequence when making a Queuing Time Table:

[Command Table]

Command Description Condition OGM xx An outgoing message is sent to the caller. "xx" applies to the OGM number. After the OGM, Music on Hold will be sent and the next event in the sequence will be activated. Wait The caller waits for the specified time while hearing a ringback tone or Music on Hold. If an OGM has not been sent to the caller, the caller hears a ringback tone. If an OGM has been sent to the caller, the caller hears Music on Hold. Sequence c Redirects to sequence c. "c" applies to the sequence number. None Overflow Redirects to the overflow destination. None Disconnect Disconnects the line. None None (No command) Redirects to the next sequence. If assigned as sequence 01, the Queuing Time Table will not be activated.

[Programming Example of Queuing Time Table]

Queuing Time Table No. Sequence*1 Sequence 01 Sequence 02 Sequence 03 Sequence 04 ... 01 OGM 01 Wait 30 s OGM 03 Overflow 02*2 OGM 02 Wait 30 s OGM 04 None 03 : : : : : :

1.9.8 ICD Group Features—VIP Call

Description

It is possible to assign a priority to incoming call distribution groups. If an extension belongs to multiple groups and the extension becomes idle, queuing calls in the groups will be distributed to the extension in priority order. Each incoming call distribution group can enable or disable the VIP Call mode. When multiple groups enable the VIP Call mode, the incoming call distribution group with the lowest numbered group has the highest priority. When multiple groups disable the VIP Call mode, queuing calls are distributed to extensions uniformly. [Example] In the call center, incoming call distribution groups 1 and 3 enable the VIP Call mode, while incoming call distribution groups 2 and 4 disable the VIP Call mode.

1.9.9 Idle Extension Hunting

Description

If a called extension is busy or in DND mode, Idle Extension Hunting redirects the incoming call to an idle member of the same idle extension hunting group, which can be programmed through system programming. Idle extensions are automatically searched according to a preprogrammed hunting type.

This feature is also known as Station Hunting.

Type	Description
Circular Hunting	An idle extension is searched for in the order specified in the idle extension hunting group in a circular way.
Terminated Hunting	An idle extension is searched for in the order specified in the idle extension hunting group until reaching the last assigned extension.

Conditions

•	Idle Extension Hunting applies to: Intercom, CO line, and doorphone calls to a single destination.
•	An extension user can belong to only one idle extension hunting group.
•	If all the searched extensions are busy: The PBX redirects the call to an overflow destination which can be assigned for each idle extension hunting group and each time mode (day/lunch/break/night) (→ 1.17.5 Time Service). [Available Destination]
	Destination Availability Wired Extension (PT/SLT/SIP Extension/T1-OPX) PS ICD Group PS Ring Group Floating Extension no. for SVM   VM Group (DTMF/DPT) External Pager (TAFAS) DISA Analog/ISDN Remote Maintenance Idle Line Access no. + Phone no.

1.9.10 INCOMING CALL FEATURES

Description

Each CO line functions as either a public line or a private line. Private lines are used to connect different PBXs and form a private network (→ 1.13.15 PRIVATE NETWORK FEATURES), while public lines connect a PBX to a public network, i.e., the telephone company. Certain PBX features are available depending on the networking type (public or private) of each CO line.

1.	Networking Type Used by Each CO Line
	Each CO line port (channel) of a CO line card or an IPCMPR card is assigned a port (channel) type which determines the CO line's networking type—public or private. → 2.8.33 [1-1] Slot—Port Property - T1 Port—Trunk Property → 2.17.2 [10-2] DIL Table & Port Settings—DIL—Trunk Property Card Type Port/Channel/Protocol Type Networking Type Public Private IPCMPR (V-IPGW) H.323   IP-GW H.323   LCOT —   T1 LCOT   GCOT   DID   TIE (E & M) OPX (EXTN.)     PRI CO   Extension     QSIG-Master   QSIG-Slave   : Enable : Available
2.	Distribution Method
	Each public CO line port (channel) can use a different method of directing calls to their destinations as they are received. Distribution Method Description Details in Direct In Line (DIL) Directs a call to a preprogrammed destination, such as an operator, based on the CO line carrying the call. • 1.4.7 DIL (Direct In Line) Direct Inward Dialing (DID) Directs a call received on a DID line to a preprogrammed destination based on the telephone number dialed by the caller. • 1.4.6 DID (Direct Inward Dialing)
	Calling Line Identification (CLI) distribution is the most customizable call distribution method available. It allows calls from specific people to be directed to specific destinations, based on the callers' telephone numbers. CLI distribution, when enabled for the current time mode, takes precedence over DIL or DID distribution. Feature Description Details in Calling Line Identification (CLI) Distribution Directs a call to its preprogrammed destination if the caller's telephone number and its CLI destination has been stored in the System Speed Dialing Table. • 1.3.13 CLI (Calling Line Identification) Distribution
3.	Available Distribution Method for Public CO Lines
	Card Type Port/Channel Type Distribution Method DIL DID LCOT —   T1 LCOT   GCOT   DID TIE (E & M) PRI CO : Enable : Available
4.	Available Destination
	The following destination types can be programmed as DIL, DID, or CLI destinations. Destination Type Availability Wired Extension (PT/SLT/SIP Extension/T1-OPX) PS ICD Group PS Ring Group Floating Extension no. for SVM VM Group (DTMF/DPT) External Pager (TAFAS) DISA Analog/ISDN Remote Maintenance Idle Line Access no. + Phone no. Trunk Group Access no. + Trunk Group no. + Phone no. Extension of Another PBX (via TIE Line, Access with PBX Code) Extension of Another PBX (via TIE Line, Access without PBX Code)
5.	Intercept Routing
	After a call has been directed to its DIL, DID, or CLI destination, the following Intercept Routing features, if programmed, can redirect the call. Type Description Details in No Answer (IRNA) If a called party does not answer a call within a preprogrammed time period (Intercept time), the call is redirected to a preprogrammed destination. • 1.9.11 Intercept Routing Busy If a called party is already handling another call, the new call is redirected to a preprogrammed destination. DND If a called party is in Do Not Disturb (DND) mode, the call is redirected to a preprogrammed destination. No Destination If a destination is not assigned, the call is redirected to an operator. • 1.9.12 Intercept Routing—No Destination

1.9.11 Intercept Routing

Description

Redirects an incoming CO line call or intercom call to a preprogrammed destination when the original destination does not, or can not, answer the call. There are four types of Intercept Routing, described below.

Type Description No Answer (IRNA)   If a called party does not answer a call within a preprogrammed time period (IRNA Timer), the call is redirected to a preprogrammed intercept destination. The assigned intercept destination of the extension port. → 2.9.5 [2-3] Timers & Counters    → Dial / IRNA / Recall / Tone—Intercept Routing No Answer (IRNA)—Day, Lunch, Break, Night    → DISA / Door / Reminder / U. Conf—DISA—Intercept Timer—Day, Lunch, Break, Night → [203] Intercept Time Busy  If a called party is already handling a call, new calls are handled as follows: – The call is redirected to the preprogrammed Intercept Routing—Busy destination. – If an Intercept Routing—Busy destination is not enabled, the caller will hear a busy tone. However, if the call is made through an LCOT or T1 [LCOT/GCOT] card, the caller hears a ringback tone. DND If a called party is in Do Not Disturb (DND) mode, the call is redirected to a preprogrammed intercept destination. No Destination If a call has no destination (i.e., if a destination is not assigned), the call is redirected to an operator. (→ 1.9.12 Intercept Routing—No Destination)

Intercept Routing redirects calls to destinations based on the original destination of the call, as shown in the table below. Different intercept destinations can be programmed for each time mode. Note that calls redirected by Intercept Routing—No Answer/DND are directed to the same destination, while Intercept Routing—Busy is directed to a separate destination, and the intercept destination for Intercept Routing—No Destination is always an operator.

When the original destination is: The Available Intercept Destination is: • Wired Extension (PT/SLT/SIP Extension/T1-OPX) • PS The destination assigned to the original extension. 2.11.1 [4-1-1] Wired Extension—Extension Settings—Intercept Destination    → Intercept Destination—When called party does not answer—Day, Lunch, Break, Night    → Intercept Destination—When Called Party is Busy 2.11.10 [4-2-1] Portable Station—Extension Settings—Intercept Destination    → Intercept Destination—When called party does not answer—Day, Lunch, Break, Night    → Intercept Destination—When Called Party is Busy → [604] Extension Intercept Destination • ICD Group The ICD Group Overflow destination assigned to the group. (→ 1.9.5 ICD Group Features—Overflow) → 2.10.12 [3-5-1] Incoming Call Distribution Group—Group Settings—Overflow No Answer—Time out & Manual Queue Redirection—Destination-Day, Lunch, Break, Night → [625] Destination for Overflow Time Expiration • VM Group (DTMF/DPT) The destination assigned to the first extension of the VM group. • DISA* If all DISA ports are busy when a call is made using DISA, one of the following can be selected through system programming: • Disable: Busy tone is sent to the caller. When using an analog CO line, a ringback tone is sent. • Operator: The call will be redirected to the operator. • AA-0, AA-9: The call will be redirected to the destination assigned to that AA number. → 2.12.3 [5-3-1] Voice Message—DISA System—Option 1—DISA Intercept—Intercept when all DISA ports are busy • PS Ring Group** • External Pager (TAFAS)** • Analog/ISDN Remote Maintenance • Other PBX Extension (TIE with no PBX Code) Not assignable (Intercept Routing is not available.)

* Intercept Routing for DISA will redirect a call only if all of the Direct Inward System Access (DISA) ports are busy. If Intercept Routing is activated after a call from DISA reaches the destination extension, the Intercept Routing settings assigned to that extension will be applied.

** By assigning the forward destination of a Virtual PS to a PS Ring Group or external pager, and assigning Intercept Routing destinations to the Virtual PS, calls to these destinations will be redirected to the Intercept Routing destination of the Virtual PS.

[Available Intercept Destination]

The following can be used as intercept destinations:

Intercept Destination Availability Wired Extension (PT/SLT/SIP Extension/T1-OPX) PS ICD Group PS Ring Group Floating Extension no. for SVM VM Group (DTMF/DPT) External Pager (TAFAS) DISA Analog/ISDN Remote Maintenance Idle Line Access no. + Phone no. Trunk Group Access no. + Trunk Group no. + Phone no. Extension of Another PBX (via TIE Line, Access with PBX Code) Extension of Another PBX (via TIE Line, Access without PBX Code)

Conditions

•	If the intercept destination is busy or in DND mode and therefore cannot receive the call:
	a) When the call was intercepted via Intercept Routing—No Answer, the call is sent back to the original destination and continues to ring at the original destination until answered. b) When the call was intercepted via Intercept Routing—Busy and arrived through an LCOT or T1 (LCOT/GCOT) card, the call waits at the original destination. If the extension has Call Waiting activated, the user will hear a call waiting tone. When the call arrived on any other card, the caller hears a busy tone. c) When the call was intercepted via Intercept Routing—DND and arrived through an LCOT or T1 (LCOT/GCOT) card, the call waits at the original destination and it rings. When the call arrived through any other card, the caller hears a busy tone.
•	If the intercept destination can, but does not, answer the call: The call continues to ring at the intercept destination until answered.
•	Intercept Routing—DND on/off Intercept Routing—DND can each be enabled or disabled for the entire system, through system programming. If enabled, calls will be routed to the appropriate destination. If disabled, a call to an extension which is in DND mode will be handled as described below, depending on the type of line carrying the call.
	→ 2.17.6 [10-4] Miscellaneous—Intercept—Intercept Routing - DND (Destination sets DND.)
	a) LCOT or T1 (LCOT/GCOT) Card: The caller will hear a ringback tone. If in DND mode, the extension will ring. b) All other lines: An outside caller will hear a busy tone and an extension caller will hear a DND tone.
•	Idle Extension Hunting If an extension is a member of an idle extension hunting group, calls to that extension will not be redirected by Intercept Routing—Busy/DND. If the extension is busy or in DND mode, calls to that extension will be redirected to the next extension in the idle extension hunting group.
•	Intercept Routing for intercom calls can be enabled or disabled on a system basis. → 2.17.6 [10-4] Miscellaneous—Intercept—Intercept Routing for Extension Call
•	IRNA Timer The IRNA timer can be set on a system basis and an extension basis for each time mode (day, lunch, break, night). → 2.11.1 [4-1-1] Wired Extension—Extension Settings—Intercept No Answer Time—Intercept No Answer Time—Day, Lunch, Break, Night
•	The Intercept Routing destination for each time mode will not apply for Intercept Routing—Busy. When the original destination is busy, the call is redirected to the Intercept Routing—Busy destination assigned through system programming. If no destination is assigned the caller will hear a busy tone.
•	The time modes that are selected for CO line calls arriving at extensions and VM groups are decided on a tenant basis.

1.9.15 IP-PT (IP Proprietary Telephone)

Description

This PBX supports the connection of IP proprietary telephones (IP-PTs), which function almost identically to normal PTs. However, they connect to the PBX over a Local Area Network (LAN), and send and receive calls using Internet Protocol (IP). IP-PTs have two Ethernet ports for connection, primary and secondary. They are connected to the PBX through a network hub or other splitting device, and can have a PC connected to the secondary Ethernet port.

[Connection Example]

Conditions

•	A V-IPEXT card or IP-EXT card is required to use IP-PTs.
•	IP-PT registration is required through system programming before an IP-PT can be used with the PBX. An IP-PT cannot be used unless an extension number is assigned. For details on how to register IP-PTs, see the IP Networking Guide.
•	The following features cannot be used with an IP-PT:
	– XDP (→ 1.13.2 Paralleled Telephone) – Digital XDP (→ 1.13.2 Paralleled Telephone) – OHCA (→ 1.12.3 OHCA (Off-hook Call Announcement)) – Walking Extension (→ 1.20.2 Walking Extension) – Using PC Phone or PC Console on a connected PC (→ 1.13.5 PC Console/PC Phone)
•	The KX-NT265 does not have a secondary Ethernet port.
•	The following optional devices are available for the KX-NT300 series IP-PT:
	– KX-NT307(PSLP1528) Bluetooth Module – KX-NT303 Add-on 12 Key Module (not available for KX-NT366) – KX-NT305 Add-on 60 Key Module (not available for KX-NT366)
•	KX-NT307(PSLP1528) Bluetooth Module A Bluetooth wireless headset can be registered to an KX-NT300 series IP-PT containing the KX-NT307(PSLP1528) Bluetooth Module through personal programming. When Headset Mode is off, the Bluetooth headset can be used to answer calls or redial. In this case, Headset Mode will turn on automatically, and will turn off after you hang up.
•	Calls made using a Bluetooth wireless headset will not be disconnected immediately when the user wanders out of range. However, if the Bluetooth wireless headset user remains out of range for a specified time period, the call will be disconnected.
•	IP-PTs can be connected to the V-IPEXT/IP-EXT card as follows:
	V-IPEXT Card IP-EXT Card KX-NT136   KX-NT265   KX-NT265 (version 2.00 or later) KX-NT300 series (except KX-NT366/KX-NT305) KX-NT366/KX-NT305

1.9.16 ISDN (INTEGRATED SERVICES DIGITAL NETWORK) FEATURES

Description

Integrated Services Digital Network (ISDN) is a digital switching and transmission network. ISDN transmits voice, data, and image in digital format. ISDN lines can be connected to public lines (CO lines), private lines (QSIG).

1.	ISDN Interface and Configuration
	Interface Type Description Port Mode Primary Rate Interface (PRI) Provides twenty-three 64 kbps B channels for communication and one 64 kbps D channel for signaling (23B + D). CO Line, QSIG—Master, QSIG—Slave*
	* → 2.8.30 [1-1] Slot—Port Property - PRI Port—Main—Port Type
2.	ISDN Supplementary Services for Public Network
	Service Description Details in Direct Inward Dialing (DID) Directs a call with a DID number to the preprogrammed destination. • 1.4.6 DID (Direct Inward Dialing) Calling Line Identification Presentation (CLIP) Sends the caller's telephone number to the network when making a call. The called party can see the number on his or her telephone display before answering the call. • 1.3.14 CLIP (Calling Line Identification Presentation) Connected Line Identification Presentation (COLP) Sends the telephone number of the answered party to the network when answering a call. The caller can see the number on his telephone display when the line is connected. Calling Line Identification Restriction (CLIR) Prevents the caller's CLI from being presented to the called party. Connected Line Identification Restriction (COLR) Prevents COLP from being sent by the answered party. Caller ID The PBX receives Caller ID information, such as the caller's name and telephone number, when a call is sent from the network. A display proprietary telephone (PT) user can see this information before answering the call. • 1.3.2 Caller ID
3.	Private Networking Connection (QSIG)
	Private networking with QSIG is possible using an ISDN line. Each ISDN port must be programmed so that each ISDN line has a "master" connection and a "slave" connection.

Conditions

•	En bloc The PBX sends all of dialed digits at once after the extension user completes dialing. The PBX recognizes the end of dialing as follows:
	– the # key is pressed (programmable). → 2.9.18 [2-9] System Options—Option 2—End of Dial Plan—[#] as End of Dial for en Bloc mode – the dialed number is a preprogrammed telephone number. → 2.10.4 [3-1-4] Dialing Plan – the inter-digit timer expires. → 2.9.5 [2-3] Timers & Counters—Dial / IRNA / Recall / Tone—Dial—Extension Inter-digit
•	Extension Number An extension number can be assigned to each ISDN port. → 2.11.1 [4-1-1] Wired Extension—Extension Settings—Main—Extension Number
