Imagine a bank where every cashier had their own queue and you, the customer, could not change queues. You could be standing waiting for service while a neighboring cashier had no customers. Placing a call on a conventional radio system can be just as frustrating. Your channel may often be busy while neighboring channels are available and under-utilised.

Just as a modern bank provides access to a pool of cashiers, trunking provides access to a shared pool of radio channels. When you want to place an individual or group call, a channel is allocated to all participants. The call takes place in private and once it's completed, the channel is returned to the pool for others to use. Sharing channels increases the availability of airtime to all users. The result is increased quality of service and reduced infrastructure and operating costs.
British
Ministry of Post and Telecommunications (MPT) defined the MPT 1327
protocol in 1988 as an open protocol and an international standard,
it has since become the most widely used trunked radio protocol in
the world.
MPT is just like the PC which has been around for some time but their performance today would never be likened to the PCs of the 1980s. It is important to remember that MPT is a digital trunking system. The call set up and all signaling for data is digital. Only the voice on traffic remains analogue. We consider this to be an advantage where speech clarity is paramount.
MPT 1327 trunking is ideally suited for providing individual or group calls, it offers fast call set up time along with a wide range of advanced features and functionality. Examples of such features include emergency and priority call management, status messaging, dynamic regrouping of users, and data/text messaging.
MPT 1327 uses a digital control channel with analogue voice channels. The digital control channel provides a data gateway that allows enhanced features including security and subscriber verification, mobile data communications, system administration, and seamless multi-site roaming.
