BusinessPhone Communication Platform 7.0
System Overview ASB 150 02 Release 15 (BusinessPhone 7.0)

## Overview Of System Functions

#### Abbreviated number

Enables an extension user to initiate a call to a pre-programmed number by dialling a directory number or pressing a key. Abbreviated numbers can be:

common |  | All extensions can use them and up to 1000 numbers can be programmed

individual |  | Programmed and used solely by the user. The capacity depends on the telephone used.

#### ACD-function

The possibility to form groups of extensions (agents) to which calls can be directed. Agents who are members of a group, receive calls on an even load basis. Incoming calls to the ACD-function will be queued if no free agent exists. If the queue is full, no agent is available or the expected waiting time in the queue has reached a pre-set threshold value, the calls will be routed to a defined overflow position.

An ACD-group consists of:

- Agents

- Users of the system telephone with special ACD function keys (see below). The main task of an ACD agent is to answer incoming calls of ACD groups to which he/she is assigned

- ACD supervisor

- Users of the system telephone with ACD function keys and special monitoring key. The main task of an ACD supervisor is to monitor the ACD groups in order to re-organize them to meet varying demands or if needed provide Agents with direct assistance on the phone.

The following ACD functions are supported:

- ACD-call code

- The ACD-call code is an arbitrary number (1-5 digits) that is entered by the agent after completion of the ACD call. Depending on the programming the agents can be forced to enter call codes for ACD and non-ACD calls. The code is assigned optional significance and can be used by a connected BP CCS to obtain statistics. For more detailed information on ACD calls it is possible to enter several different call codes.

- ACD-clerical function

- The ACD-clerical function provides the agent with a certain period of time between the previous and the next incoming ACD call. This clerical time can either be pre-defined in the system or controlled by a programmable function key on the agent telephone. The clerical time can be displayed on the telephone.

- ACD-help key

- Key assigned to an ACD-agent. The key is used to attract the attention of the agent supervisor. The key can be used during an ongoing call.

- ACD-monitoring key

- Function key for ACD-supervisor also called ACD supervisor key. A key is programmed for each supervised agent. The key's lamp indicates the status of the individual agent.

- ACD-night service

- This function enables authorized extensions to switch either defined ACD groups or all ACD groups to the night mode in order to route incoming calls to a defined answering position, after office hours.

- ACD-pause key

- Key assigned to an ACD-agent. The key permits the agent to leave his / her position for a short break or to make outgoing business calls without logging out as an agent. During the pause state the agent is not available for incoming ACD calls.

- ACD-PIN code

- Each ACD-agent is assigned a PIN-code (Personal Identity Number) which he/she uses to log on to the system.
- There can be a maximum of 1000 PIN-codes in the system. This enables the Call Centre Supervisor to sort call data by agent.

- ACD-overflow

- Under certain conditions the ACD overflow function offers alternative routing to incoming callers to an ACD group if the call cannot be handled. These conditions can be:

- overflow on maximum queue length
- overflow if no agent is present
- overflow if expected waiting time in the queue reaches a pre-set threshold value.

- ACD-voice answers

- Voice answers denote recorded voice messages that are supplied to a caller in the following traffic cases.

- Incoming calls to an ACD group will be answered by a general greeting
- Incoming calls to an ACD group which cannot be routed directly to a free agent will receive a message informing about the expected waiting time or the position in the queue
- Calls being allocated to a free agent will receive a common greeting for the ACD group and an individual agent greeting.

#### Account number

The possibility, during an outgoing and incoming external call, to dial an account number that can be identified when a printout of the CIL-function takes place.

#### Alpha Tagging via CTI

With Alpha Tagging via CTI it is possible to show the public caller's name in addition to his A-number on the display of system and IP instruments.

#### Alternative routing

A call that, normally is made via a certain route, can be redirected to another route in the event of congestion, by adding the required extra call digits.

#### Alarm function

The possibility to send an alarm message to up to 8 alarm centres via a system telephone (for instance bathroom alarm in hotels). The alarm centre can read via the display from which telephone the alarm was sent.

#### Answer position

This is a directory number that answers calls to a designated trunk. The directory number is stated in the system data.

#### A-Number transfer via MFC and MFE

Some countries using MFC and MFE signalling in the public network also provide the A-number to the customer, enabling number display of the external party on system telephones.

#### Authorization code

A personal code that can be assigned to extension users. The code enables the user to block her/his own telephone, or to utilize own categories from another telephone.

#### Automated Attendant

This is a voice-supported function guiding an external caller through menus to establish connections to a defined directory number in the system, to another voice menu or to dial the desired directory number. Especially useful as DID with DTMF.

#### Automatic call-back

Automatic call-back can be requested by an internal caller to get in touch with a free or a busy extension and trunk as soon as it is used or becomes free again.

#### Automatic redial

Automatic redial can be requested by the user to initiate an automatic redial of the last dialled external number when the call was not successful due to busy or no answer.

#### Background music

The possibility for the user to listen to music or other information via the telephone’s loudspeaker, if the telephone is on hook.

#### BackStage

BackStage is a PC application that brings the benefits of Computer–Telephony Integration (CTI) to enterprises in a simple, straightforward way. It provides features and functions that improve efficiency, productivity of the user’s working environment, and it allows applications such as Microsoft’s Outlook, Excel, Word and Access to be “telephony-enabled”.

#### Braille Operator

For operators with impaired vision using an enhanced Operator software (PC-Operator) and a Braille keyboard connected to a PC.

#### Bypass of call diversion and follow me.

In case of an urgent call, the function "Bypass call diversion" and "follow-me" permits authorized extensions to break through all kind of activated call forwardings.

#### Call Accounting

Can be a PC-based call accounting program of which certified products are provided.

#### Call announcing (OPERATOR function)

Before extending a call, the OPERATOR informs the called party that a call is waiting.

#### Call Cabin

The Call Cabin function - means that a company offers the service to make telephone calls, which are charged immediately afterwards. For this function there are normally dedicated telephones, which are mostly situated in a cabin (e.g. in the foyer of a hotel or in the “telephone shop” itself).

#### Call Centre Assistant (CCA)

CCA is a peripheral 3rd party CTI software application based on BusinessLink for Windows to provide ACD-agents and ACD-supervisors with advanced call management, Call Centre statistics and lists of abandoned queued calls. It provides also integration into CCS and Operator Suite (Operator Workstation).

#### Call Centre Supervisor (CCS)

Call Centre Supervisor enables real time monitoring of the Call Centre activities (agent performance, call handling, service level, etc.) and generation of a history report for management information and planning purposes.

#### Call Diversion

Each extension can be programmed to reroute a call to a divertee position. Selection whether internal calls or external and internal calls are possible to be diverted:

direct |  | All calls to the extension are diverted directly to the divertee position. See also Follow me.

on no-reply |  | Incoming calls that remain unanswered after a predetermined time are diverted to the divertee position.

on busy |  | If a called extension is busy, the call will be diverted to the divertee position.

#### Call Information Logging (CIL)-function

Information relevant to each call can be obtained via a V.24 interface (port) in the system. A printer or peripheral PC-based CIL-equipment can be connected to this port for presentation and analysis of stored call data.

#### Call List

The Call List includes a complete history of recently made calls (maximum 20). It offers system telephones access to previously dialed/received, internal/external numbers. Scrolling through the list shows also the time and date of a call, indicates the number of call attempts and offers a call back possibility.

#### Call Metering

The possibility to detect metering pulses or cost data from the public exchange. The information from the meters/cost data, together with extension number, dialled number and time, can be transferred to a connected printer or peripheral processing unit (see Call Accounting).

An extension equipped with DBC 222, DBC 223, or DBC 2224 telephones offers the following options to keep track of the costs during outgoing external calls:

- Call metering during the call

- The display shows either costs, number of pulses or duration (not applicable for the DBC 224).

- Call metering for the previous call

- The user can read out the costs of the last outgoing external call.

- Read out of the accumulated costs for own extension.
- Read out and print out of the accumulated costs per extension and trunk lines from authorized user with DBC 223 or DBC 224. If a printer is connected to the system also a print out can be initiated.
- Operator supervised call

- For an ordered call the OPERATOR can connect call metering equipment and the OPERATOR is recalled when the call ends. On recall the OPERATOR can read the number of metering pulses or costs and controls who is charged.

#### Call pick-up

The possibility for an extension user to answer calls of other extensions. There are three kinds of call pick-up:

- individual

- The ringing call is picked up by dialling the extension number of the called extension followed by a post digit.

- extension group

- Both the called extension and pick-up extension must belong to the same group. The call is answered by dialling a special code (digit).

- common

- Calls to this function will be placed in a common queue and signalled to all extensions in the group.

#### Call waiting

Acoustic signal in a telephone connection to inform the extension user that another call has been camped-on to the extension.

#### Camp-on

A call to a busy extension can be camped on to it, i.e. the call is queued to the extension. When the extension goes free, the camped-on call will ring automatically. See Call waiting.

#### Categorization

Each extension and trunk in the system can be assigned various categories. Categorization of extensions is also possible for:

- Facility category, that is the facilities to which the extension shall have access
- Traffic group
- TCD-category
- Common abbreviated number category

#### Clock and diary

In idle state DBC 222, DBC 223 and DBC 224 telephones display the time and date. The clock is also used for the call information logging facility, the reminder function, wake up and LCR. By using an ISDN trunk interface, clock and diary can be synchronized with the one in the public network.

#### Common bell

This facility gives all extensions the possibility to pick up the call from an extension that has been pre-defined as a common-bell extension.

#### Conference

The possibility to interconnect up to six parties (conferees) for one common conference call. The permitted number of external parties can be determined by programming.

#### Connection state messages

Tone messages and other information that is displayed in the course of a call to another party.

#### Conversation Recording

Any authorized extension user can initiate the recording of an ongoing conversation. The opposite party of the conversation can be either an internal (except operator, analog, cordless and IP-Phones) or an external party, but only speech connection between not more than 2 parties can be recorded.

The recorded conversation will be stored in the individual mailbox of the initiator as a normal voice message. Conversation recording can be easily initiated by using a function key to toggle between starting or stopping the recording session.

#### Computer Telephony Integration (CTI)

The Computer Telephony Integration link offers an intelligent connection between ASB 150 02 and a Server PC. The Server PC converts the telephony events into CSTA (ECMA) standard events and provides all the clients in a network with this information. The interchange of information between the Server PC and the Network Clients is done by using CSTA standard (TSAPI).

#### CTI-Groups

The Automated Attendant function can also be used in combination with the Computer Telephony Integration function, where the customer gets the possibility to enter the own ID number in a voice menu. Depending on this ID number the external computer chooses the respective extension and informs the system to which extension the customer is transferred to.

#### Direct dialling-in (DDI)

The possibility of a public network subscriber to call an extension in ASB 150 02 directly without the help of the OPERATOR. DID is market-dependent and might not be available on all markets.

#### Dictaphone function

Messages recorded by using the dictaphone function of ASB 150 02 are stored in the personal (individual) mailbox and are treated like a normal voice message. For recording of important notes during work new routines have been introduced to simplify the start of dictaphone messages especially for cordless phone users. For retrieving the dictaphone messages the same procedures as for retrieving normal voice messages can be used.

#### Directory numbers

A directory number is a number that is assigned:

- a line position, that is an extension or a trunk
- a facility group number, ACD-number etc.

Directory numbers can have 1,2,3 or 4-digits. Directory numbers can be freely selected as long as they are not incompatible.

#### DISA with password control

DISA (=Direct Inward System Access) with password control enables an external caller to dial via DTMF to a defined directory number. After dialling one’s own extension number and a password, it is possible to establish outgoing calls with the costs accounted to one’s own extension number.

Further on the DISA function can also be used to activate and to deactivate the function individual external diversion of the own extension.

#### Display functions

System telephones with display show various information, depending on the connection case. This information can be:

- number and name of caller
- time and date
- connection message
- text information
- message system
- ACD queue information
- clerical time (elapsed or remaining)
- number of calls in the ISDN callers list
- diversion information
- temperature

#### Diversion bypass (OPERATOR function)

When a call extension has ongoing diversion, the OPERATOR can bypass the diversion by pressing a special key.

#### Door Interface Unit (DIU)

This is a wall-mounted box connected to the exchange via two analog extensions and connects simple door phones located e.g. at the entrance to offices or an apartment block. Pressing the door phone button, a call to a defined directory number is initiated. The second extension line is used to open an electric door lock.

#### Dual line function

The possibility for a system telephone to accept calls on Line 2 even if Line 1 is occupied.

#### Fax extension

An extension to which a dedicated FAX can be connected.

#### Fictive number

A directory number not connected physically to any extension position, but which can be used as answer position for a common answering function. Incoming calls can be queued to the fictive number as well as diverted to a defined destination. A maximum of 1000 fictive numbers can be defined in the system.

#### Flexible numbering scheme

The possibility to assign extensions, trunks and certain facilities an optional directory number with 1 - 4 digits.

#### Follow me

This function allows calls to a certain directory number to be diverted to another directory number.

#### Forced release (OPERATOR function)

When the OPERATOR intrudes on an ongoing call, he/she can disconnect the non-relevant party.

#### Function key

Key with permanent function on a system telephone.

#### Group listening

A function in DBC 220, DBC 222, DBC 223 telephones which makes it possible to use the handset together with the built-in loudspeaker.

Everybody in the room will hear the conversation but only one person can talk via the handset.

#### Group (PBX)-hunting

A group of extensions can be called via a common number. The call distribution to the group member can either be according to serial distribution or parallel distribution. In case of serial distribution, the first free extension in the group receives the call, in case of the parallel distribution all free extensions of the group will receive the call.

#### Hands-free dialling

The loudspeaker on DBC 210 and DBC 199 telephones is used to monitor calls during call setup.

#### Hands-free operation

A telephone having both a built-in loudspeaker and a microphone. A conversation can be held without lifting the handset.

#### Hotel function

ASB 150 02 can be utilized as communication system for hotels. Extensions can be freely distributed among:

- Guest room extensions

- A telephone in a guestroom, providing special functions such as:

- "wake-up" orders
- "do-not-disturb" orders
- "loudspeaker" (emergency alerting, announcements, background music)
- "message-waiting" lamp.
- direct call keys to various services

- Administration extensions

- An DBC 223 or DBC 224 telephone that, via programming, is given the possibility to check guests in and out, to read room status and to order "wake-up" times for guests.

- Service extensions

- Extension in a hotel system that provides guests with service, e.g. restaurant, room service.

The system supports the following hotel functions:

- Blocking room-to-room dialling

- Function used by administrative staff in order to prohibit all guest rooms or an individual one to build up calls to other guests. The function can also be configured to activate and deactivate automatically the general blocking of room to room dialling at certain hours during the day.

- Blocking direct in-dialling to the guest rooms

- Function used by the administrative staff in order to prevent that incoming calls during night hours will be directly connected to specific or all guest rooms.

- Check in/Check out

- Function used by administrative staff in order to:

- bar and unbar the guest room extension
- define guest details

- e.g. name, check-in check-out date, language, credit cards.

- read out the accumulated costs.

- Guests can be checked in/out directly via:

- an Administration telephone
- Front Office System (FOS)

- PC-program in hotel telephone system for use by reception personnel to check-in and check-out guests, order wake up, control costs etc.

- Customer’s Hotel computer

- Customer-specific solution for hotel use that can be interconnected with ASB 150 02. For interconnection to function satisfactorily both computer and ASB 150 02 must use the same protocol.

- Do not disturb

- Guests can order "Do not disturb" individually. At night-time the reception can prevent all guest-room -to-guestroom calls. Such calls will be routed to the operator or to a voice message facility.

- Room status

- Function for cleaning staff to indicate that the room has now been cleaned. Room status can be read on the reception telephone.

- Wake-up function

- "Wake-up" can be ordered by guests or via the reception extension. Guests receive a voice announcement confirming their ordered "Wake-up" time in one out of three languages. Upon reaching the ordered time, the guest is called. On answering the guest receives a pre-recorded announcement.

#### Hotline

A call to a pre-programmed number is initiated automatically when the user lifts the handset.

#### Identification (OPERATOR function)

When the operator calls a busy extension, he/she can identify the latter's conversation partner by pressing a dedicated key.

#### Immediate answer

Calls to a hands-free telephone give immediate speech connection, which means that no key depression is needed to answer the call. Internal calls are presented as immediate speech connection, external calls with a ring signal.

#### Incoming calls

All types of calls to a telephone in the system. Incoming calls can be presented to:

- line 1
- line 2
- trunk key
- dedicated intercom line
- answer key for ACD-number
- key for loudspeaker paging
- key for call interception

#### Individual external diversion

The Individual External Diversion (IED) facility allows the user to activate a call diversion of his own extension to a free defined and up to 24 digits long external number. The function can be activated/deactivated either direct from the own extension or remotely via DISA.

#### Individual number translation

This feature supports a number translation of external incoming DDI and corporate network calls and vice versa.

The reason for a number translation is relevant in cases such as when the DDI or corporate number range provided by the public or private network does not fit, or is not available for use as internal number range within the system.

#### Information

Information to callers stating the reason for absence. The relevant extension user inserts the message, which can be a verbal or a text message.

#### Inquiry

Denotes a call that is initiated during an ongoing call. When the call is initiated, the ongoing call will be parked automatically.

#### Internal traffic

Calls to or conversations with other extensions belonging to the system.

#### Intercom line

A reserved connection between two parties who will never encounter busy. The connection has a dedicated key on the relevant system telephones. The function is utilized e.g. for secretary connections.

#### Intrusion

The possibility for an extension with a special category to intrude on an ongoing call after encountering busy tone.

#### IP-Extension

The integration of IP-Extension does not only provide just voice over IP. The IP-Extension can gain from most of the system functions by having nearly the same speech quality as the users of the Digital System Telephones is accustomed to.

The IP-Extension function can be used at each office desk as well as in home-working scenarios, when being connected via a Remote Access Service to the organization’s data network. Remote users can access their work files, email and voice mail, take part in conference calls and use other phone facilities by just using a single PC with an installed Ericsson BackStage or MS Netmeeting Client.

Further the IP-Extension function has a big operational advantage for the customer’s LAN administrator. Apart from the unified cabling for voice and data, it is simple to add, move and remover users, it is just a question of plugging a PC or terminal to the LAN.

#### IP Trunking

ASB 150 02 IP trunking is enabled through the standard based H.323 implementation on the systems IPU board. Known as IP Trunking, it is a method of transmitting Voice-over-IP (VoIP) used by long distance carriers around the globe to transmit voice between Local Access and Transport Areas (LATAs) and between countries. When used in the local loop, it is known as IP Loop Trunking. IP Loop Trunking makes it possible for a carrier to build a single access network that significantly reduces capital and operational costs.

IP Loop Trunking converts voice to IP packets at the customers premises in the ASB 150 02 (in the local loop), then aggregates it into the existing carriers IP backbone. With IP Loop Trunking, Quality of Service is handled simply since the local loop is a closed network, with a known number of subscribers. Voice-over-IP traffic is given the highest priority, and data transmissions receive a lower priority. Once the voice traffic arrives in the carriers network it can be routed through the IP backbone to a carrier grade Voice-over-IP gateway to hop-off at any other place. IP Loop Trunking makes it impossible for callers to notice any difference between calls made from traditional digital or analogue trunks.

#### ISDN features

The system supports three types of ISDN interfaces:

- Primary Rate Access to the network side
  (T-Interface; 30B+D)
- Basic Access to network side
  (T-Interface; 2B + D)
- Basic Access on extension side
  (S-Interface; 2B + D)

The scope of services includes "Basic Call" and the following supplementary services:

- Advice of charge (AOC)

- The charging information will be shown on the display (see also call-metering facility).

- Call transfer:

- The S-Interface user can initiate a call transfer during a inquiry call via:

- explicit call transfer (ISDN ECT SS)
- hook-on (proprietary service, command 1965)
- keypad facility *4# (stimulus service)

- Calling line identification presentation (CLIP) and restriction (CLIR).

- The function enables or disables presentation of the calling number on an incoming call.

- Connected line identification (COLP) and restriction (COLR).

- The function enables or disables the possibility to see the identity of the connected line on an outgoing call.

- Direct dialling in (DDI)

- All calls from the network will be routed to the dialled extension numbers.

- Hold & Retrieve

- The S-Interface user can put a call on hold (parked system telephone can hear MoH) and retrieve the call from hold, thus if the user starts a secondary inquiry call then the primary call is automatically put on hold respectively retrieved from hold.

- Malicious call identification (MCID).

- The user may activate the MCID function in the ISDN-network in order to trap the calling party.

- Multiple subscriber number (MSN)

- This feature is only applicable on the S-interface and enables individual addressing of the terminal on the passive bus.

- Subaddressing (SUB)

- This feature is only applicable on the S-interface. It enables the caller to expand the addressing of the terminals on the passive bus beyond the assigned directory number of the S-interface.

- Terminal Portability (Suspend & Resume)

- The S-Interface user can park the conversation partner (SUSPEND of call) for a max. of 3 minutes before the parked call must be reconnected again (RESUME of call). During this time the S-interface user can make a disconnection/re-connection of the terminal for a change of location (the terminal must be connected to on the same S-interface).

ISDN Caller list has been replaced by Call List

#### Key-system

A key system denotes a system providing all or selected trunks on directly represented keys (trunk-line keys) on system telephones.

#### Last external number redial

The system automatically stores all the dialled digits during an external call, which can be re-transmitted in a later procedure. Numbers dialled after speech connection are not stored.

#### Least Cost Routing

This facility selects the most economic carrier for a dialled external destination. The number is analyses and – using the information stored in the database – the cheapest connection is set up.

#### Loop keys (OPERATOR function)

The DBC 224, DBC 214 and DBC 663 telephones have four keys for calls that are being monitored. Calls extended via these loop keys can be re-accessed at any time.

#### Loudspeaker paging

The possibility to page acoustically all or a group of extensions. The paging extensions must have telephones with loudspeakers. Up to eight groups of extensions can be paged.

#### Mailbox system

This integrated system offers internal and external callers the possibility to leave messages in a users mailbox. Waiting messages can be retrieved by internal and external users supported by voice prompts. A waiting message is indicated merely by a flashing lamp on a telephone set. Internal callers from DBC 223 and DBC 224 telephones can retrieve messages using display and function keys. DBC 220, DBC 222, DBC 425, analog and Cordless phones can retrieve voice messages by dialling a function code.

#### Menu selection keys

On a DBC 223, DBC 224 and DBC 425 telephones there are 4 keys whose function is indicated by a menu on the bottom line of the display.

#### Messages

Messages can be exchanged by analog and digital extensions in the system. Messages can be spoken or consist of text. A message can also be merely a flashing lamp on the telephone of the desired party. When the latter returns, he/she can contact the first party by pressing the key adjacent to the flashing lamp. Analog, IP and Cordless phones receive a special dial tone.

#### Mobile extension

A mobile subscriber, be it 2G, 2.5G or 3G or any standard GSM, GPRS, D-AMPS, UMTS, can be used like an extension in ASB 150 02. The mobile user is able to use ASB 150 02 services like an analog extension such as inquiry, short number dialing, camp-on, intrusion, call back, etc.

#### Monitoring (OPERATOR function)

One of the OPERATOR's link keys can be used for monitoring. This enables the OPERATOR to monitor this external call while, at the same time, extending new calls.

#### Music-on-hold

External or internal callers waiting in park state will receive music or other recorded information either during the transfer procedure only or until the speech connection between them is established. The music source can either be the VMU-HD/MFU or a peripheral equipment connected to the CPU‑D5 (CPU‑D4), BTU‑A or BTU‑C.

For Call Centre solutions, each ACD group can be configured with a separate music-on-hold source.

#### Name selection

Function available on DBC 220, DBC 222, DBC 223, and DBC 224 telephones that enables a 4-digit number to be stored on a name selection (dial-by-name key). On depression of the key, the number will be transmitted.

#### Networking

##### Analog

The following basic networking features are possible together with E&M tie line or loop signalling:

- Up to 16 different routes, which enables several exchanges to be interconnected to the system
- Open and closed numbering scheme with the possibility to add or delete digits
- Transit traffic
- Alternative routing (2 alternatives).

##### Digital

The digital networking features provided differ according to whether the Standard or Full Networking Package FECU is used.

Basic Networking capability

The Basic Networking features form the core of both Standard and Full Networking packages. They include:

- Common corporate numbering plan

- Allows a common and uniform numbering plan to be used by all users in the private network. It combines co-ordinated and location code-based numbering schemes, allowing numbers with up to eight digits: up to four to identify the node, and up to four to identify the extension. Up to 1000 corporate network nodes may be defined.

- Private network routing

- Ensures that the best possible route for private network traffic is always selected to minimize costs and make maximum use of private network resources. One first-choice and three alternative routes are possible. The alternatives can be both digital (ISDN) and analog.

- Basic (2B+D) and Primary Rate (30B+D) interfaces can be configured to provide both the Q-reference point, for QSIG leased line connections, and the T‑reference point, for switched public ISDN connections with DSS1.

Standard Networking capability

The Standard Networking Package (QSIG Networking Package) allows ASB 150 02 to interwork with multi-vendor corporate networks containing other ECMA/ETSI QSIG-compliant PBXs over leased lines. Features supported include:

- Basic Call

- The basic call set-up protocol, with Transit Counter to limit the number of hops between corporate network nodes to avoid looping, and Party Category to ensure appropriate handling of the corporate network calls according to the type of party involved.
  The Generic Functional Protocol is implemented to support the standard QSIG supplementary services

- Calling/Connected Line Identification Presentation and Restriction (CLIP/COLP, CLIR)

- Allows the number of the calling/connected party to be presented, or restricted from being presented, on the called/calling party’s telephone display.

- Calling/Connected Name Identification Presentation/Restriction (CNIP/CONP, CNIR)

- Allows the calling/connected party’s name to be presented, or restricted from being presented, on the called/calling party’s telephone display.

- Advice of charge

- If the public network provides Advice of Charge information for calls, this information is presented on the corporate network telephone displays.

Full Networking capability

The Full Networking Package provides interworking between ASB 150 02 systems, or between ASB 150 02 systems and the ASB 501 04 system, over leased or switched lines, based on the proprietary protocol and services, carried by UUS1,2,3. In addition to the functionality of the Standard Networking Package, a wide range of further services is supported.

- Basic Call

- Similar to the QSIG Basic Call functionality, including Transit Counter and Party Category, with the addition of the proprietary Travelling Class Mark. This enables or restricts a user’s access to certain routing options in the corporate network.

In addition, corporate network extension features include:

- Call Back on busy (or on no reply)

- Allows the corporate network calling party to be automatically called back when the called corporate network extension becomes free (or active) again.

- Call Diversion (direct, on busy, and on No Reply), Follow Me and Diversion Bypass

- These features allow a corporate network user to set up different types of call diversion, and to bypass call diversion by dialling a special feature code.

- Calling/Connected Line Identification Presentation/Restriction

- Equivalent to the QSIG standard CLIP/COLP and CLIR functions.

- Calling/Connected Name Identification Presentation/Restriction

- Equivalent to the QSIG standard CNIP/CONP and CNIR functions.

- Call Transfer

- Allows ongoing calls to be transferred in the corporate network.

- Camp on Busy

- Notifies a busy corporate network extension that a call is waiting.

- External Message Waiting

- Indicates a message waiting for an ASB 150 02 user where the voice message system is located in the ASB 501 04 system.

- Intrusion

- Allows an extension user to intrude into a corporate network call, if the called extension is busy.

- Network Account Code

- Allows call charging information to be associated with different users/accounts in the private network.

The Full Networking capability also supports Centralized Operator functionality in “active mode”, where the operator is located in the ASB 150 02 system, or “passive mode”, where the operator is located in an ASB 501 04 or any other ASB 150 02 system in the network. In addition to the extension features listed above, Centralized Operator features include (except Call Back on no-reply):

- Call to Operator, Rerouting to Operator and Extending
- Intrusion and Forced Release

- These features allow the central operator to intrude into a user’s call and to release the unwanted party

- Night Service Notification

- Allows ASB 150 02 to handle the notification from the headquarters (ASB 501 04) system that it is passing into night service mode, and consequently (according to the ASB 150 02 programming) to reroute incoming calls for ASB 150 02 users to an alternative night answering position, other than the headquarters system.

##### Voice over IP lines

The IPU board of ASB 150 02 R14 hosts a H.323 compliant trunk gateway and optional a Gatekeeper. With the function “Networking via Voice over IP lines”, ASB 150 02 provides an integrated trunk gateway functionality between circuit switched telephony and IP network.

Up to release 13 only proprietary IP networking was possible. Since release 14 additionally the Gatekeeper and the H.323 trunk gateway functionality based on the IP Unit (IPU) can be used to build up a standard H.323 network by using the existing customer LAN/WAN environment alternatively to leased lines.

The function “Networking via Voice over IP lines” is primarily based on the functionality of “Networking via digital lines”. From a networking functionality it does not matter whether the connection between the nodes is built up via leased lines or IP lines over the corporate network (Intranet).

Apart from the networking functionality the following additional functionality will be provided for voice calls.

- 4, 8 or 16 simultaneous bi-directional voice channels according to the used license.
- Address translation between telephony (PNR number) and network (IP number) number.
- Definition of Voice Transmission Quality (VTQ) for VoIP calls on individual extension levels by using the Voice-codecs: G.711, G723.1 and G.729 Annex A (with Annex B)
- To provide Quality of Service for Voice over IP calls “Type of Service “(priorisation of voice packets) is supported in the IP header.
- DTMF tone handling
- Manual hand over to circuit switched lines in case of insufficient voice quality.
- Echo cancellation
- Comfort noise generation
- Silence suppression

#### Night service
