Explanation / Answer

LEt us first know basics about PBX then we will come to the question:

1) PBX or Private Branch Exchange refers to the system of communication that allows the user within a company or organisations to communicate with each other. It is similar to small telephone network in which each device has a small number assigned to it usually 3 or 4 digit number.

2) A centrex is a service provided by some service provided that might be a company or an organisation for the communication. In centrex all the infrasytructure needed to implement it is owned by the service provider and hence it make it easier to acquire.
