`
`5.3.1 M PT 132'!" '-
`
`This section presents a briefintroduction to the MPT 1327 related standards
`for analog trunking. These standards, first published in 1988 under the aus-
`pices of the UK. Department of Trade and Industry (DTI), have beCome
`the de facto standard for radio trunking systems throughout the world out—
`side North America.
`
`'l'he standards are now administered by the Radiocommunications
`AgenCy and c0pies are available from their Web site (httpdiwwvmadiogov
`.ukf). The standards cover the following areas:
`
`MPT 1327: Basic protocol rules for analog trunked land mobile radio
`systems.
`
`MP1" 1343: Specific implementation of the protocol rules for commer-
`cial radio networks.
`
`MPT 1347: Performance requirements to be met by the network fixed
`equipment.
`
`MPT 1352: Test schedule for approval of radio units on to the trunked
`network.
`
`'
`
`.
`
`Note that the protocol rules and test schedules relate only to the radio
`air interface, but this technology achieves the same level of interoperability
`between agencies and manufacturers as that shown in Figure 5.17 (from Pro-
`ject 25). There has been no attempt to standardize any interfaces within the
`infraSIruCturE: or between infrastructures or to establish standard gateways to
`external services {such as the PSTN or PABX).

`
`The level of functionality delivered by Ml’T 1327’ is typical for that
`time (circa 1988) and comprises:
`
`I Analog voice;
`
`a Circuit mode data typically at 1,200 bps;
`
`- Status messages on the control channel;
`
`- Short data messages, also on the control channel.
`
`The payload for the short data messages is 46 bits of free format data,
`and up to four such messages can be sent to a single address at a time.
`
`5.3.1.3 NewarkArehitecture
`
`the system manufacturer is
`Because the infrastructure is not standardized,
`able to select the appropriate network layout for the user application. A typi-
`cal LMR trunking system is shown in Figure 5.5, and this is appropriate for
`MPT 1327 implementations. Traditionally, large communication systems
`have been made up from hierarchical switching network architecture with
`much of the system intelligence concentrated in a few system nodes. Unfor-
`tunately, such systems do not exhibit graceful degradation and often a single
`failure can lead to complete loss of service.
`in a distributed architecture,
`the system intelligence is distributed
`throughout the network, leading to improved reliability and inherent fall-
`back capability. These are important Considerations to be aware ofwhen ana—
`lyzing the offerings from different manufacturers.
`The MPT 1327 radio system is based on simple FDMA principles and
`in many ways parallels APCO Project 16 concepts. There can be any number
`oftraffic channels per base station. limited only by the manufacturer’s imple-
`mentation (typical maximum is 32 channels).
`A typical public safety implementation may have six traffic channels
`supported by a single control channel. The protocol supports the option for
`dedicated 0r time—shared (between different sites) control channel or even
`
`minimum mode operation in which the control channel can revert to carry—
`ing traffic in heavily loaded situations.
`The MPT 1327 protocol does not support handover between sites, and
`most system implementations use large cells and have radio coverage limited
`by receiver noise level considerations rather than by cochannel interference.
`This convention means that MPT 1327 has followed the typical LMR
`implementation for widely spaced radio base high-level sites, rather than the
