User Manual

1.2.6 Calling without Restrictions

This PBX supports various types of groups.

CO Line Group

CO lines can be grouped into CO line groups based on carrier, CO line type, etc. (

LCOT CO Line Group Number [402]). Several settings can be assigned on a CO line group basis. All CO lines belonging to a CO line group follow the programming for that CO line group.
Each CO line can belong to only one CO line group. CO lines are assigned to a CO line group based on their port numbers (for LCOT and PRI cards) or their channel numbers (for T1 cards).

Extension Group

Extensions can be grouped into extension groups (

Extension Group [603]). Extension groups then compose the following groups:

a)	Tenant ( 2.2.3 Tenant Service)
b)	Call Pickup Group (See below.)
c)	Paging Group (See below.)

Every extension must belong to one extension group and cannot belong to more than one extension group.
Assignable Extensions: Proprietary telephone (PT)/single line telephone (SLT)/portable station (PS)/T1-OPX

[Example]

2.1.

Call Pickup Group (

Extension Groups of a Pickup Group [650])

Using the Group Call Pickup feature, extensions can answer any calls within the call pickup group to which they belong. One extension group can belong to several call pickup groups.
(

1.4.1.3 Call Pickup)

[Example]

2.2.

Paging Group (

Extension Groups of a Paging Group [640])

Using the Paging feature, extensions can page or answer a page within their groups. One extension group or external pager (loudspeaker) can belong to several paging groups.
(

1.14.1 Paging)

[Example]

Idle Extension Hunting Group

If a called extension is busy or in Do Not Disturb (DND) mode, Idle Extension Hunting redirects the incoming call to an idle member of the same idle extension hunting group. Members are programmed through system programming (

Idle Extension Hunting Group Member [681]). When calls are received, idle extensions are automatically searched for according to a preprogrammed hunting type: Circular Hunting or Terminated Hunting (

Idle Extension Hunting Type [680]).
(

1.2.1 Idle Extension Hunting)

Incoming Call Distribution Group (ICD Group)

An ICD group is a group of extensions which receives incoming calls directed to the group (

ICD Group Member [620]). Each ICD group has a floating extension number (

ICD Group Floating Extension Number [622]) and name (

ICD Group Name [623]). One extension can belong to multiple ICD groups.
Assignable Extensions: PT/SLT/PS/T1-OPX/PS ring group
(

1.2.2 Incoming Call Distribution (ICD) Group Features)

[Example]

VM Group

There are two types of VM groups, explained below.

Type

Description

VM (DPT) Group

A group of DPT ports (

VM Group Floating Extension Number [660]) which use Voice Mail DPT (Digital) Integration features.
One DPT port can belong to only one group.

VM (DTMF) Group

A group of SLT ports which use Voice Mail DTMF Integration features.
One SLT port can belong to only one group.

(

1.21.1 Voice Mail (VM) Group)

[Example]

PS Ring Group

A PS ring group is a group of PS extensions which receives incoming calls directed to the group. Each group has a floating extension number and name assigned through system programming. One PS can belong to multiple PS ring groups.
(

1.22.2 PS Ring Group)

Tenant service is a cost-effective method of providing PBX services to different offices or companies located in the same building, while using only one PBX.

Tenant Configuration

1.1.

Tenant Members

Extensions are assigned to a tenant indirectly; they are assigned to extension groups, and these extension groups are assigned to tenants. An extension can belong to only one extension group and an extension group can belong to only one tenant, therefore an extension can belong to only one tenant. (

2.2.2 Group)

1.2.

Time Service

Time modes are used by many PBX features to determine how they will function during different times of day (

2.2.4 Time Service). The start and end times of each time mode (day/lunch/break/night) for each day of the week are programmed in a Time Table. Each Time Table has a number which corresponds to the tenant number of the tenant it serves. (Tenant 1 uses Time Table 1, etc.)

[Example of Tenant Configuration]

System Management

Each of the following system management items can be assigned to each tenant.

a)	Tenant Operator: Determines the destination for calls directed to the tenant's operator. If no operator is designated, the PBX operator will serve as the tenant's operator. ( 2.2.5 Operator Features)
b)	ARS Mode: Determines under which circumstances Automatic Route Selection (ARS) operates for calls made by the tenant's extensions – either when a call is made using the Idle Line Access method, or when any CO Line Access method is used. ( 1.5.5.3 CO Line Access). The ARS mode for each tenant can also be programmed to be the same ARS mode assigned to the entire PBX, or turned off. ( 1.9.1 Automatic Route Selection (ARS))
c)	Audio Source for Music on Hold: Determines the audio source for the Music on Hold heard by the tenant's callers. Either a tone or a specific background music (BGM) number can be used. The audio source for each tenant can also be programmed to use the same audio source used for Music on Hold assigned to the entire PBX. ( 1.12.4 Music on Hold)

Call Blocking

Through Class of Service (COS) programming, it is possible to:

1.	Prevent extensions of one tenant from calling extensions of another tenant. (Tenant-to-Tenant Call Block)
2.	Limit the CO line groups which can be used by the extensions of each tenant. (External Call Block)

3.1.

Tenant-to-Tenant Call Block

Using Internal Call Block, certain features, such as making intercom calls, can be restricted based on the COS assigned to extensions. (

1.1.2.2 Internal Call Block) Well-planned COS programming can prevent extensions of one tenant from:

—

Calling an extension or doorphone which belongs to another tenant

—

Picking up calls ringing at extensions belonging to another tenant (

1.4.1.3 Call Pickup)

—

Retrieving calls being held by another tenant (

1.12.1 Call Hold)

[Programming Example: Internal Call Block]

In this example:

Internal Call Block is employed to block calls between certain tenants.
Each extension in a tenant is assigned a COS that is not assigned to extensions which belong to another tenant.

Extensions in Tenant 1 are either COS 1 or 2. They can make calls to extensions in Tenants 1, 2, and 3.

Extensions in Tenant 2 are either COS 3 or 4. They can make calls to extensions in Tenants 1 and 2, but not 3.

Extensions in Tenant 3 are either COS 5 or 6. They can make calls to other extensions in Tenant 3 only.

3.2.

External Call Block

If multiple tenants are using the PBX, the External Call Block feature should be programmed to control which COS numbers are allowed to access which CO line groups. By preventing certain COS numbers from accessing certain CO line groups, each tenant can be given its own CO line groups which no other tenant can access.

[Programming Example: External Call Block]

In this example:

External Call Block is employed to prevent tenants from accessing all CO line groups except the ones designated to them. Each extension in a tenant is assigned a COS that is not assigned to extensions which belong to another tenant.

Extensions in Tenant 1 are either COS 1 or 2. They can access CO line groups 1 and 2.

Extensions in Tenant 2 are either COS 3 or 4. They can access CO line groups 3 and 4.

Extensions in Tenant 3 are either COS 5 or 6. They can access CO line groups 5 and 6.

•

The following features used by incoming call distribution (ICD) group are determined by the tenant number assigned to them (

1.2.2.1 Incoming Call Distribution (ICD) Group Features–OVERVIEW):

—

The Music on Hold heard by a caller while waiting in a queue.

—

The Time Table used by the ICD group to determine the current time mode. An overflow destination and Queuing Time Table can be assigned for each time mode.

Time modes are used by many PBX features to determine how they will function during different times of day. For example, incoming calls can be directed to sales staff during the day and to a Voice Processing System (VPS) at night, extension users can be prohibited from making long distance calls during lunch time, etc.
There are four time modes–day, lunch, break, and night. The start and end times of each time mode are programmed for each day of the week in a Time Table. Each Time Table has a number which corresponds to the tenant it serves, i.e., Tenant 1 uses Time Table 1, etc.

Time Service Switching Mode

The current time mode can switch automatically to another time mode at the preprogrammed time assigned in the Time Table. It is possible, however, to switch time modes manually.
Whether time modes are normally switched manually or automatically is determined through system programming (

Time Service Switching Mode [101]). Each tenant is assigned a switching mode.

Time Mode Switching

Description

Condition

Automatic

The current time mode will switch automatically to another time mode at the time programmed in the tenant's Time Table, and can be switched manually by pressing the Time Service button or by dialing the Time Service Switch feature number.

The current time mode (day/lunch/break/night) and the switching mode (automatic/manual) can be switched manually by an extension assigned as a manager, or by an extension whose Class of Service (COS) is authorized (

Time Service Manual Switching [514]).

Manual

The current time mode will switch only when the Time Service button is pressed or when the Time Service Switch feature number is dialed.

Time Table

Each tenant has a Time Table that is used when the tenant is in Automatic Time Service Switching mode. Each Time Table has four basic modes–day, lunch, break, and night–and also provides for multiple "breaks", such as morning breaks and afternoon breaks, and multiple "days", such as the morning shift and the afternoon shift following lunch.
A tenant's Time Table is programmed to control when each time mode starts (and therefore, ends) and can be programmed separately for each day of the week.
Each Time Table has a number which corresponds to the tenant number of the tenant it serves. (Tenant 1 uses Time Table 1, etc.)

[Programming Example: Time Table]

[Visualization of Time Schedule for Tenant 1]

Note that in this example, the day mode (Day 2) resumes automatically when the break mode (Break 1) ends.

[Visualization of Time Schedule for Other Tenants]

Note that time modes can be arranged as they are needed (for example, night mode can occur in the morning and afternoon, if necessary) and not all time modes need to be used in a tenant's time schedule.
Also note that Tenant 4's Break 1 is followed by the night mode because no end time is programmed for the break.

Features Using Time Service

The following features can be programmed separately for each time mode:

a)	Destination of incoming CO line calls (Direct In Line (DIL)/Direct Inward Dialing (DID)) ( 1.1.1 Incoming CO Line Call Features)
b)	Destination of calls handled by Intercept Routing ( 1.1.1.5 Intercept Routing)
c)	Destination of calls that are overflowed while waiting in a queue for an available agent of an incoming call distribution (ICD) group ( 1.2.2.5 Overflow Feature)
d)	Destination of incoming doorphone calls ( 1.15.1 Doorphone Call)
e)	Destination of Operator Calls ( 2.2.5 Operator Features)
f)	Toll Restriction (TRS) level of each COS
g)	COS numbers which are permitted/restricted to access certain CO line groups (External Call Block) ( 1.5.5.3 CO Line Access)
h)	Outgoing Message (OGM) for Timed Reminder ( 1.24.4 Timed Reminder)

[Programming Example: DID Table]

The DID Table can be programmed to direct calls to a different destination for each time mode based on the number dialed by the caller. Calls can, for example, be directed to an ICD group during the day mode, or to the Voice Mail (VM) service of a VPS during the lunch and night modes.

Explanation:

A CO line call with the DID number "123-4567" is received at 20:00.

1)	The call will be handled by Time Table 1.
2)	The current time mode is "night" (shown in "Programming Example: Time Table", above).
3)	The call is directed to extension 150, which is a floating extension number used by the VPS (programming not shown here).

Holiday Mode

The PBX can also accommodate 24 different holidays. The start and end date of each holiday can be programmed, and all holidays are assigned a single time mode. For example, if the "night" mode is assigned as the time mode for holidays, and a holiday begins December 31st and ends January 1st, all PBX features will use their "night" settings from 0:00 A.M. on December 31st until 0:00 A.M. on January 1st.

Time Service Button

A flexible button can be customized as one of the following Time Service buttons:

a)	Day/Night button
b)	Day/Night/Lunch button
c)	Day/Night/Break button
d)	Day/Night/Lunch/Break button

These buttons can be used to switch the current time mode: pressing the Day/Night button will toggle between the day and night modes, for example.
Each Time Service button will display the current time mode using a different light pattern or color, as shown below.

Light Pattern

Current Time Mode

Off

Day

Red on

Night

Green on

Lunch

Slow green flashing

Break

Holiday

Note
	Pressing a Time Service button will change the current time mode only if the COS assigned to the extension is authorized to do so ( Time Service Manual Switching [514]) or if the extension is assigned as a manager. All other extension users can press this button on their proprietary telephones (PTs) to display the current time mode.

•

The start times of the following time modes can be specified through PC programming as well as PT programming (

Time Service Starting Time [102]).

—

Day 1 and 2

—

Lunch

—

Night

The start and end times of the following break modes can be specified through PC programming only.

—

Break 1

—

Break 2

—

Break 3

Note that if an end time is programmed for a break, the day mode will start or resume at this time, as shown previously in "Visualization of Time Schedule for Tenant 1" example. If no end time is programmed, the break will continue until the start of the next time mode, as shown in Time Table 4 in "Visualization of Time Schedule for Other Tenants".

•

Time Service Switching Mode (Automatic/Manual) Button
Any flexible button can be customized as the Time Service Switching Mode (Automatic/Manual) button.

User Manual

This PBX supports separate operators for both the PBX and each tenant. Any extension or incoming call distribution (ICD) group can be designated as an operator. Operators are the destination of Operator Calls.

Type

Description

PBX operator

A different extension or ICD group can be assigned as a PBX operator for each time mode (

Operator Assignment [006]).

Tenant operator

Each tenant can be assigned an operator. This operator is the same for all time modes and can be either an extension or an ICD group. A tenant's operator does not need to be an extension assigned to the tenant it serves.

Operator Call
An extension user can call an operator by dialing the preprogrammed Operator Call feature number, often simply, "0". When an Operator Call is made, the call is directed to the tenant operator of the calling extension's tenant. If no tenant operator is assigned, the call is routed to the PBX operator. The tenant number of the calling extension determines the current time mode which is then used to determine the current PBX operator.
If neither a tenant operator nor a PBX operator is assigned, the caller will hear a reorder tone.

•	An extension or ICD group can be assigned as both a tenant operator and the PBX operator.
•	The same tenant operator can be assigned as the operator for multiple tenants.

User Manual

1.2.1 Basic Calling

An extension assigned as a manager (manager extension) is allowed to use certain features which most extensions cannot. Class of Service (COS) programming determines which extensions are manager extensions (

Manager Assignment [511]) and can therefore use the following manager features:
