MPT Trunking

Since 1988, when the British Ministry of Post and Telecommunications (MPT) defined the MPT 1327 protocol as an open protocol and an international standard.

MPT 1327 trunking is ideally suited for providing individual calls, and a wide range of advanced features and functionality to support field units. Examples of such features include emergency and priority call management, status messaging, dynamic regrouping of users, and data/text messaging.

User applications requiring the use of MDT (mobile data terminals), in-vehicle printers, and GPS-based AVL (automated vehicle location) systems can find these value-added peripherals and software available from vendors taking advantage of the open (non-proprietary) standard interfaces supported by MPT 1327. MPT 1327 uses the "message trunking" scheme and is ideal for either individual or group calling. In message trunking a speech channel is assigned and dedicated for the duration of a call. Every subscriber radio is allocated a unique ESN (Electronic Serial Number) which can be individually verified to give a high degree of system control and subscriber management.

MPT 1327 uses a digital control channel with analogue voice channels. The digital control channel provides a data gateway that allows supporting enhanced features including security and subscriber verification, mobile data communications, system administration, and seamless multi-site roaming. No other protocol allows this kind of versatility in the economy of scale inherent in MPT 1327.
