There are several types of Private Branch Exchange (PBX) systems, primarily categorized into three main types: analog PBX, digital PBX, and IP PBX. Analog PBX systems use traditional telephone lines and are becoming less common. Digital PBX systems utilize digital signaling and can offer more features than analog systems. IP PBX systems leverage internet protocol technology, allowing for more advanced features, scalability, and integration with other communication tools.
PBX stands for Private Branch eXchange. It is a medium for large private phone system.A Digital PBX is simply a PBX that does not use analog signals internally.

IP and digital PBX may be related to each other because IP is already digital wherein it uses internet and data networks to transmit multimedia like voice, fax, message, music, etc. Some of the types of PBX systems are: Virtual PBX Phone System IP-PBX Phone System PBX Phone System You can check virtualpbxcompare.com to see provider's listing in extended table of all the feature, price and plans for their system.
Key system is the basic and traditional phone system we have. Calls are routed through PSTN to establish calls. The newest development which are the PBX and VOIP PBX uses the hi speed broadband Internet connection to carry over voice or analog signals. It uses gateways to convert analog signal into digital signal.
The kind of equipment that is necessary for a PBX system includes IP and analog telephone. It also includes other equipment that involves setting up the network to meet your needs.
There are several types of telephone switchboards, including Manual Switchboards (MSB), Centralized Automatic Switchboards (CAS), and Private Branch Exchanges (PBX). Manual switchboards require operators to connect calls manually, while CAS systems automatically route calls using digital or analog technology. PBX systems are used within organizations to manage internal and external calls efficiently. Common abbreviations include MSB, CAS, and PBX.
A Cisco PBX IP is used as a stackable integration device that emulates a digital or analog phone, and connects over a Local Area Network. This device is only available in the United States, Canada, and Western Europe.
The typical analog circuit that connects between the customer premises and the central office (phone company) has two copper wires. These wires are referred to as TIP and RING. There is typically a -48 VDC signal between the TIP and RING wires which is typically powered by the central office switch. When a standard analog phone is connected to the analog circuit and the handset is picked up (going off hook) a switch on the phone closes the connection between the TIP and RING wires and current is drawn from the central office switch. The switch determines that current is being drawn and provides dial tone so the person on the phone knows it is time to dial a number. A PBX FXO circuit running loop start looks like a standard analog phone to the central office switch. Now, one problem that is often seen with loop start circuits is a condition called "glare". Glare occurs when a call comes in on the analog line from the central office at the same time the PBX wants to seize the same line to make an outgoing call. The ground start protocol was designed to eliminate this problem with glare. From the PBX side, the RING lead is grounded first, then the central office circuit must ground the TIP lead before the PBX can close the loop between TIP and RING.
