Guidelines of Multi Line Commercial Telephone Systems
For medium-sized enterprises, providing key systems, multiple functions and can normally be extended to up to 35 handsets. Key systems use a central control unit called the Key System Unit (KSU) to control the telephone network connected to your business, and all outgoing or incoming calls. In recent years, key systems have become so advanced that many rival PBX systems in the form of standard features and customization.
For large companies of more than 35-40 employees, a PBX system is a way to go. PBX systems offer the greatest amount of functionality and highly expandable. PBX Central Terminal controls all phone systems in the same way that the system is the key, but can do a lot more phones. The majority of PBX systems will become standard functions of the telephone system, if needed, as they relate to large companies. PBX systems are highly programmable and may be configured to meet specific company requires. The only disadvantage to PBX systems are the total costs compared to key systems and KSU-less systems. Yet, if the company needs a lot more than 30 phones, or might in the future, PBX is the only option.
Factors that determine the size system you need is the number of rows and number of extensions you need. The lines are the number of phone lines outside your telephone system can be connected simultaneously. Extensions are needed for each phone or other device that the company needs to connect to the PBX. Knowing both can give an idea of what an ideal phone system for your business.
