What is PBX / EPABX / KTS ?

PBX = Private Branch Exchange
EPABX = Electronically Private Automated Branch Exchange
KTS = Key Telephone System

These all are the names by which we refer to the private exchanges. They are used to provide telephone services in a company using a minimal amount of external telephone lines.

With the help of EPABX, the persons can talk internally for no cost. If they want to make an external call, then only they need to pay. There can be >=8 internal phones in the company, and >= 2 trunk telephone lines.

What all services are provided by PBX ?

PBX provides all basic telephony services such as making calls, receiving calls, putting calls on hold, etc.

But with these minimal functions, they also provide some additional functions. They may include :

1. Direct Inward Dialing
2. Do Not Disturb Service
3. Opening / Closing Door
4. Seizing calls
5. Store Call Data on some PC / print directly to printer
6. Locking certain lines
7. Barge-in.
8. and lot more to list here....

Functionally, the PBX performs three main duties:

Establishing connections (circuits) between the telephone sets of two users. (e.g. mapping a dialed number to a physical phone, ensuring the phone isn't already busy)
Maintaining such connections as long as the users require them. (i.e. channeling voice signals between the users)
Providing information for accounting purposes (e.g. metering calls)

In addition to these basic functions, PBXs offer many other calling features and capabilities, with different manufacturers providing different features in an effort to differentiate their products. Common capabilities include (manufacturers may have a different name for each capability):

Auto Attendant

Automatic call distributor

Automated directory services (where callers can be routed to a given employee by keying or speaking the letters of the employee's name)

Automatic ring back

Call accounting

Call forwarding on absence

Call forwarding on busy

Call park

Call pick-up

Call transfer

Call waiting

Camp-on

Conference call

Custom greetings

Customised Abbreviated dialing (Speed Dialing)

Direct Inward Dialing

Direct Inward System Access (DISA) (the ability to access internal features from an outside telephone line)

Do Not Disturb (DND)

Follow-me

Interactive voice response

Music on hold

Night service

Shared message boxes (where a department can have a shared voicemail box)

Voice mail

Voice broadcasting

Voice paging (PA system)

Thanks for support chethan. Now lets extend it in all possible parts, with all knowledge that we have.

In this post, I'll discuss about LCR in short.

LCR stands for Least Cost Routing.

It's a table built into hardware of PBX and is used to select phone line when someone wants to make call. This table is defined and maintained by the system administrator. In this table, we specify the ordering and priority of lines that should be followed while making call.

In LCR, for each group of trunks, permissions are also checked before making a call.

Hey chethan, please start discussing each capability of PBX you've mentioned. I'm with you and will also explain them. Please start their explanation.

If you want me to answer how we can perform some functions using computer, I'm ready to explain it's interfaces and methods, that I've used.

Please reply ....
