A business telephone system is a multiline telephone scheme typically used inwards job concern environments, encompassing systems ranging from pocket-size key telephone systems to large-scale private branch exchanges.

A job concern telephone scheme differs from an installation of several telephones amongst multiple fundamental business office (CO) lines inwards that the CO lines used are straight controllable inwards key telephone systems from multiple telephone stations, in addition to that such a scheme oft provides additional features related to telephone band handling. Business telephone systems are oft broadly classified into key telephone systems, in addition to private branch exchanges, but many hybrid systems exist.

A key telephone scheme was originally distinguished from a private branch commutation (PBX) inwards that it did non require an operator or attendant at the switchboard to constitute connections betwixt the fundamental business office trunks in addition to stations, or betwixt stations. Technologically, private branch exchanges part lineage amongst fundamental business office telephone systems, in addition to inwards larger or to a greater extent than complex systems, may contender a fundamental business office scheme inwards capacity in addition to features. With a key telephone system, a station user could command the connections straight using draw buttons, which indicated the condition of lines amongst built-in lamps.

Key telephone system

Key telephone systems are primarily defined yesteryear arrangements amongst private draw choice buttons for each available telephone line. The earliest systems were known every bit wiring plans in addition to but consisted of telephone sets, keys, lamps, in addition to wiring.

Key was a Bell System term of fine art for a customer-controlled switching scheme such every bit the line-buttons on the phones associated amongst such systems.

The wiring plans evolved into modular hardware edifice blocks amongst a diverseness of functionality in addition to services inwards the 1A key telephone scheme developed inwards the Bell System inwards the 1930s.

Key systems tin last built using iii principal architectures: electromechanical shared-control, electronic shared-control, or independent key sets.

New installations of key telephone systems stimulate got teach less common, every bit hybrid systems in addition to private branch exchanges of comparable size stimulate got like terms in addition to greater functionality.

Electromechanical shared-control key system

Before the advent of large-scale integrated circuits, key systems were typically composed of electromechanical components (relays) every bit were larger telephone switching systems.

The systems marketed inwards North America every bit the 1A, 6A, 1A1 in addition to the 1A2 Key System are typical examples in addition to sold for many decades. The 1A solid unit of measurement of Western Electric Company (WECo) key telephone units (KTUs) were introduced inwards the belatedly 1930s in addition to remained inwards work to the 1950s. 1A equipment was primitive in addition to required at to the lowest degree 2 KTUs per line; ane for draw termination in addition to ane for station (telephone instrument) termination. The telephone musical instrument commonly used yesteryear 1A systems was the WECo 300-series telephone. Introduced inwards 1953, 1A1 key systems simplified wiring amongst a unmarried KTU for both draw in addition to station termination, in addition to increased the features available. As the 1A1 systems became commonplace, requirements for intercom features grew. The original intercom KTUs, WECo Model 207, were wired for a unmarried beak link, that is, a unmarried conversation on the intercom at a time. The WECo 6A dial intercom scheme provided 2 beak links in addition to was oft installed every bit the dial intercom inwards a 1A1 or 1A2 key system. The 6A systems were complex, troublesome in addition to expensive, in addition to never became popular. The advent of 1A2 applied scientific discipline inwards the 1964 simplified key scheme laid upwards in addition to maintenance. These continued to last used throughout the 1980s, when the arrival of electronic key systems amongst their easier installation in addition to greater features signaled the halt of electromechanical key systems.

Two lesser-known key systems were used at airports for air traffic command communications, the 102 in addition to 302 key systems. These were uniquely designed for communications betwixt the air traffic command tower in addition to radar approach command (RAPCON) or solid set down command approach (GCA), in addition to included radio draw connections.

Automatic Electric Company also produced a solid unit of measurement of key telephone equipment, roughly of it compatible amongst Western Electric equipment, but it did non gain the widespread work enjoyed yesteryear Western Electric equipment.

Electronic shared-control system

With the advent of LSI ICs, the same architecture could last implemented much less expensively than was possible using relays. In addition, it was possible to eliminate the many-wire cabling in addition to supervene upon it amongst much simpler cable like to (or fifty-fifty identical to) that used yesteryear non-key systems. Electronic shared-control systems led chop-chop to the modern hybrid telephone system, every bit the features of PBX in addition to key scheme chop-chop merged. One of the most recognized such systems is the AT&T Merlin.

Additionally, these to a greater extent than modern systems allowed a various laid of features including:

  • Answering machine functions
  • Automatic telephone band accounting
  • Caller ID
  • Remote supervision of the entire system
  • Selection of signaling sounds
  • Speed dialing
  • Station-specific limitations (such every bit no long distance access or no paging)

Features could last added or modified but using software, allowing tardily customization of these systems. The stations were easier to maintain than the previous electromechanical key systems, every bit they used efficient LEDs instead of incandescent low-cal bulbs for draw condition indication.

LSI also allowed smaller systems to distribute the command (and features) into private telephone sets that don’t require whatsoever unmarried shared command unit. Generally, these systems are used amongst a relatively few telephone sets in addition to it is oft to a greater extent than hard to maintain the characteristic laid (such every bit speed-dialing numbers) inwards synchrony betwixt the various sets.

Hybrid key telephone system

Into the 21st century, the distinction betwixt key systems in addition to PBX systems has teach increasingly blurred. Early electronic key systems used dedicated handsets which displayed in addition to allowed access to all connected PSTN lines in addition to stations.

The modern key scheme straightaway supports SIP, ISDN, analog handsets (in improver to its ain proprietary handsets – usually digital) every bit good every bit a raft of features to a greater extent than traditionally found on larger PBX systems. Their back upwards for both analog in addition to digital signaling, in addition to of roughly PBX functionality gives rising to the hybrid designation.

A hybrid scheme typically has roughly telephone band appearance buttons that straight stand upwards for to private lines and/or stations, but may also back upwards direct dialing to extensions or exterior lines without selecting a draw appearance.

The modern key scheme is usually fully digital, although analog variants persist in addition to roughly systems implement VOIP services. Effectively, the aspects that distinguish a PBX from a hybrid key scheme are the amount, compass in addition to complexity of the features in addition to facilities offered.

Hybrid systems are a mutual tool inwards the fiscal services manufacture used on trading floors. These advanced hybrid key systems to a greater extent than oft than non entirely require attached PBXs for interaction amongst back-office staff in addition to voicemail. These systems commonly stimulate got their forepart halt units referred to every bit Turrets in addition to are notable for their presentation of hoot-n-holler circuits. Multiple Hoots are presented to multiple users over multiplexed speakers to multiple locations.

Private branch exchange

A private branch commutation (PBX) is a telephone commutation or switching scheme that serves a private organisation in addition to performs concentration of fundamental business office lines or trunks in addition to provides intercommunication betwixt a large publish of telephone stations inwards the organization. The fundamental business office lines provide connections to the populace switched telephone network in addition to the concentration facial expression of a PBX permits the shared work of these lines betwixt all stations inwards the organization. The intercommunication aspect allows 2 or to a greater extent than stations to constitute telephone or conferencing calls betwixt them without using the fundamental business office equipment.

Each PBX-connected station, such every bit a telephone set, a fax machine, or a figurer modem, is oft referred to every bit an extension in addition to has a designated extension telephone publish that may or may non last mapped automatically to the numbering programme of the fundamental business office in addition to the telephone publish block allocated to the PBX.

Initially, PBX systems offered the primary wages of terms savings for internal telephone calls: treatment the circuit switching locally reduced charges for telephone service via central-office lines. As PBX systems gained popularity, they began to characteristic services non available inwards the populace network, such every bit hunt groups, telephone band forwarding, in addition to extension dialing. From the 1960s a simulated PBX known every bit Centrex provided like features from the fundamental telephone exchange.

A PBX differs from a key telephone scheme (KTS) inwards that users of a key scheme manually select their ain outgoing lines on special telephone sets that command buttons for this purpose, piece PBXs select the outgoing draw automatically or, formerly, yesteryear an operator. The telephone sets connected to a PBX reach non unremarkably stimulate got special keys for central-office draw control, but it is non uncommon for key systems to last connected to a PBX to extend its services.

A PBX, inwards contrast to a key system, employs an organizational numbering programme for its stations. In addition, a dial programme determines whether additional digit sequences must last prefixed when dialing to obtain access to a central-office trunk. Modern number-analysis systems permit users to dial internal in addition to external telephone numbers without special codes to distinguish the intended destination.

History

The term PBX originated when switchboard operators managed society switchboards manually using cord circuits. As automated electromechanical switches in addition to afterwards electronic switching systems gradually replaced the manual systems, the terms private automatic branch exchange (PABX) in addition to private manual branch exchange (PMBX) differentiated them. Solid-state digital systems were sometimes referred to every bit electronic private automatic branch exchanges (EPABX). As of 2016, the term PBX is yesteryear far the most widely recognized. The acronym straightaway applies to all types of complex, in-house telephony switching systems.

Two pregnant developments during the 1990s led to novel types of PBX systems. One was the massive growth of information networks in addition to increased populace understanding of package switching. Companies needed packet-switched networks for data, in addition to then using them for telephone calls proved tempting, in addition to the availability of the Internet every bit a global delivery-system made packet-switched communications fifty-fifty to a greater extent than attractive. These factors led to the evolution of the phonation over IP PBX, or IP-PBX.

The other tendency involved the persuasion of focusing on nub competence. PBX services had ever been hard to accommodate for smaller companies, in addition to many companies realized that treatment their ain telephony was non their nub competence. These considerations gave rising to the concept of the hosted PBX. In wireline telephony, the original hosted PBX was the Centrex service provided yesteryear telcos since the 1960s; afterwards competitive offerings evolved into the modern competitive local commutation carrier. In phonation over IP, hosted solutions are easier to implement every bit the PBX may last located at in addition to managed yesteryear whatsoever telephone service provider, connecting to the private extensions via the Internet. The upstream provider no longer needs to run direct, local leased lines to the served premises.

System components

A PBX oft includes:

  • Cabinets, closets, vaults in addition to other housings.
  • Console or switchboard allows the operator to command incoming calls.
  • Interconnecting wires in addition to cables.
  • Logic cards, switching in addition to command cards, might cards in addition to related devices that facilitate PBX operation.
  • Microcontroller or microcomputer for arbitrary information processing, command in addition to logic.
  • Outside telco trunks that deliver signals to (and send them from) the PBX.
  • Stations or telephone sets, sometimes called lines.
  • The PBX’s internal switching network.
  • Uninterruptible might render (UPS) consisting of sensors, might switches in addition to batteries.

Current trends

Since the advent of Internet telephony (Voice over IP) technologies, PBX evolution has tended toward the IP PBX, which uses the Internet Protocol to send calls. Most modern PBXs back upwards VoIP. ISDN PBX systems also replaced roughly traditional PBXs inwards the 1990s, every bit ISDN offers features such every bit conference calling, telephone band forwarding, in addition to programmable caller ID. As of 2015 ISDN is existence phased out yesteryear most major telecommunication carriers throughout Europe inwards favour of all-IP networks, amongst roughly expecting consummate migration yesteryear 2025 Originally having started every bit an organization’s manual switchboard or attendant console operated yesteryear a telephone operator or exactly but the operator, PBXs stimulate got evolved into VoIP centers that are hosted yesteryear the operators or fifty-fifty manufacturers.

Even though VoIP is considered the hereafter of telephony, the circuit switched network remains the nub of communications, in addition to the existing PBX systems are competitive inwards services amongst modern IP systems. Five distinct scenarios exist:

  • Hosted/virtual PBX (hosted in addition to circuit-switched) or traditional Centrex
  • IP Centrex or hosted/virtual IP (hosted in addition to packet-switched)
  • IP PBX (private in addition to packet-switched)
  • Mobile PBX solution (mobile phones replacing or used inwards combination amongst fixed phones)
  • PBX (private in addition to circuit-switched)

For the alternative to telephone band from IP network to the circuit-switched PSTN (SS7/ISUP), the hosted solutions include interconnecting media gateways.

Home in addition to small-business usage

Historically, the expense of full-fledged PBX systems has set them out of accomplish of pocket-size businesses in addition to individuals. However, since the 1990s many small, consumer-grade in addition to consumer-size PBXs stimulate got teach available. These systems are non comparable inwards size, robustness or flexibility to commercial-grade PBXs, but nonetheless provide many features.

The showtime consumer PBX systems used analog (POTS) telephone lines, typically supporting 4 private analog in addition to ane populace analog line. They were the size of a pocket-size cigar box. In Europe these systems for analog phones were followed yesteryear consumer-grade PBXs for ISDN. Using pocket-size PBXs for ISDN is a logical step, since the ISDN basic charge per unit of measurement interface provides 2 logical telephone lines (via 2 ISDN B channels) which tin last used inwards parallel. With the adoption of VoIP yesteryear consumers, consumer VoIP PBXs stimulate got appeared, amongst PBX functions becoming unproblematic additional software features of consumer-grade routers in addition to switches. Additionally, many telecommunication providers straightaway offering Hosted PBX systems where the provider genuinely hosts the PBX in addition to the telephone handsets are connected to it through an mesh connection.

Open source projects stimulate got provided PBX-style features since the 1990s. These projects provide flexibility, features, in addition to programmability.

PBX functions

Functionally, the PBX performs 4 master copy telephone band processing duties:

  • Establishing connections (circuits) betwixt the telephone sets of 2 users (e.g. mapping a dialed publish to a physical phone, ensuring the telephone isn’t already busy)
  • Maintaining such connections every bit long every bit the users require them (i.e. channelling phonation signals betwixt the users)
  • Disconnecting those connections every bit per the user’s requirement
  • Providing information for accounting purposes (e.g. metering calls)

In improver to these basic functions, PBXs offering many other calling features in addition to capabilities, amongst unlike manufacturers providing unlike features inwards an attempt to differentiate their products. Common capabilities include (manufacturers may stimulate got a unlike mention for each capability):

  • Auto attendant
  • Auto dialing
  • Automated directory services (where callers tin last routed to a given employee yesteryear keying or speaking the letters of the employee’s name)
  • Automatic telephone band distributor
  • Automatic band back
  • Busy override
  • Call blocking
  • Call forwarding on busy or absence
  • Call logging
  • Call park
  • Call pick-up
  • Call transfer
  • Call waiting
  • Camp-on
  • Conference call
  • Custom greetings
  • Customized abbreviated dialing (Speed dialing)
  • Direct inward dialing (DID)
  • Direct inward scheme access (DISA) (the might to access internal features from an exterior telephone line)
  • Do non disturb (DND)
  • Follow-me, also known every bit find-me: Determines the routing of incoming calls. The commutation is configured amongst a listing of numbers for a person. When a telephone band is received for that person, the commutation routes it to each publish on the listing inwards plow until either the telephone band is answered or the listing is exhausted (at which dot the telephone band may last routed to a phonation postal service system).
  • Interactive phonation response
  • Local Connection: Another useful attribute of a hosted PBX is the might to stimulate got a local publish inwards cities inwards which you lot are non physically present. This service essentially lets you lot create a virtual business office presence anywhere inwards the world.
  • Music on hold
  • Night service
  • Public address phonation paging
  • Shared message boxes (where a subdivision tin stimulate got a shared voicemail box)
  • Voice mail
  • Voice message broadcasting
  • Welcome message

Interface standards

Interfaces for connecting extensions to a PBX include:

  • DECT – a touchstone for connecting cordless phones.
  • Internet Protocol – For example, H.323 in addition to SIP.
  • POTS (plain old telephone service) – the mutual two-wire interface used inwards most homes. This is inexpensive in addition to effective, in addition to allows most whatsoever touchstone telephone to last used every bit an extension.
  • proprietary – the manufacturer has defined a protocol. One tin entirely connect the manufacturer’s sets to their PBX, but the reach goodness is to a greater extent than visible information displayed and/or specific business office buttons.

Interfaces for connecting PBXs to each other include:

  • DPNSS – for connecting PBXs to body lines. Standardized yesteryear British Telecom, this usually runs over E1 (E-carrier) physical circuits.
  • Internet Protocol – H.323 in addition to the Session Initiation Protocol (SIP) are IP based solutions for multimedia sessions.
  • Primary charge per unit of measurement interface (ISDN) – Provided over T1 (23 bearer channels in addition to 1 signaling channel) or E1 carriers.
  • Proprietary protocols – if equipment from several manufacturers is on site, the work of a touchstone protocol is required.
  • QSIG – for connecting PBXs to each other, usually runs over T1 (T-carrier) or E1 (E-carrier) physical circuits.

Interfaces for connecting PBXs to body lines include:

  • Internet Protocol – H.323, SIP, MGCP, in addition to Inter-Asterisk eXchange protocols operate over IP in addition to are supported yesteryear roughly network providers.
  • ISDN – the most mutual digital touchstone for fixed telephony devices. This tin last supplied inwards either Basic (2 circuit capacity) or Primary (24 or thirty circuit capacity) versions. Most medium to large companies would work Primary ISDN circuits carried on T1 or E1 physical connections.
  • RBS (robbed chip signaling) – delivers 24 digital circuits over a four-wire (T1) interface
  • standard POTS (plain old telephone service) lines – the mutual two-wire interface used inwards most domestic homes. This is adequate entirely for smaller systems, in addition to tin endure from non existence able to notice incoming calls when trying to create an outbound telephone band (commonly called glare).

Interfaces for collecting information from the PBX:

  • File – the PBX generates a file containing the telephone band records from the PBX.
  • Network port (listen mode) – an external application connects to the TCP or UDP port. The PBX streams information to the application.
  • Network port (server mode) – the PBX connects to roughly other application or buffer.
  • Serial interface – historically used to impress every telephone band tape to a series printer. In modern systems a software application connects via series cable to this port.

A information tape from a PBX or other telecommunication scheme that provides the statistics for a telephone telephone band is usually termed a call especial record (CDR) or a Station Messaging Detail Record (SMDR).

Hosted PBX systems

Virtual PBX systems or hosted PBX systems deliver PBX functionality every bit a service, available over the populace switched telephone network (PSTN) or the Internet. Hosted PBXs are typically provided yesteryear a telephone society or service provider, using equipment located inwards the premises of a telephone commutation or the provider’s information center. This agency the client does non require to purchase or install PBX equipment. Generally the service is provided yesteryear a lease understanding in addition to the provider can, inwards roughly configurations, work the same switching equipment to service multiple hosted PBX customers.

The showtime hosted PBX services were feature-rich compared to most premises-based systems of the time. Some PBX functions, such every bit follow-me calling, appeared inwards a hosted service earlier they became available inwards hardware PBX equipment. Since introduction, updates in addition to novel offerings stimulate got moved characteristic sets inwards both directions. It is possible to teach hosted PBX services that include characteristic sets from minimal functionality to advanced characteristic combinations.

In improver to the features available from premises-based PBX systems, hosted-PBX:

  • allows a unmarried publish to last presented for the entire company, despite its existence geographically distributed. Influenza A virus subtype H5N1 society could fifty-fifty select to stimulate got no premises, amongst workers connected from habitation using their domestic telephones but receiving the same features every bit whatsoever PBX user.
  • allows multimodal access, where employees access the network via a diverseness of telecommunication systems, including POTS, ISDN, cellular phones, in addition to VOIP. This allows ane extension to band inwards multiple locations (either concurrently or sequentially).
  • allows scalability in addition to then that a larger scheme is non needed if novel employees are hired, in addition to and then that resources are non wasted if the publish of employees is reduced.
  • eliminates the require for companies to care or pay for on-site hardware maintenance.
  • supports integration amongst custom toll plans (that allow intra society calls, fifty-fifty from private premises, to last dialed at a cheaper rate) in addition to integrated billing in addition to accounting (where calls made on a private draw but on the company’s behalf are billed centrally to the company).

Hosted PBX providers

The ongoing migration of most major telecommunication carriers to IP based networks, coupled amongst the rising inwards Cloud Communications has resulted inwards a pregnant rising inwards the uptake of hosted PBX solutions.

Mobile PBX

A mobile PBX is a hosted PBX service that extends fixed-line PBX functionality to mobile devices such every bit cellular handsets, smartphones in addition to PDA phones yesteryear provisioning them every bit extensions. Mobile PBX services also tin include fixed-line phones. Mobile PBX systems are unlike from other hosted PBX systems that but forrad information or calls to mobile phones yesteryear allowing the mobile telephone itself, through the work of buttons, keys in addition to other input devices, to command PBX telephone functions in addition to to care communications without having to telephone band into the scheme first.

A mobile PBX may exploit the functionality available inwards smartphones to run custom applications to implement the PBX specific functionality.

In addition, a mobile PBX may create extension identifiers for each handset that allow to dial other jail energy cell phones inwards the PBX via their extension shortcut, instead of a PSTN number.

IP-PBX

An IP PBX handles phonation signals nether Internet protocol, bringing benefits for figurer telephony integration (CTI). An IP-PBX tin be every bit physical hardware, or tin send out its functions virtually, performing the call-routing activities of the traditional PBX or key scheme every bit a software system. The virtual version is also called a ” -Soft PBX -“.
