4 La Troncalizacion surgio primero en la Telefonia
TRONCOS CENTRAL CENTRAL Taking the common telephone network service would be improved by providing a multi-line telephone trunk between exchanges so that your call would be connected when the network has other calls on it. These lines would be shared by the subscribers on both exchanges to make distant calls to each other. This type of trunk networking is the principle on which all telephone networks designed. The inter-trunk lines become a shared communication resource between all exchanges and these are accessed by the use of STD dialling. The trunks are carried over physical copper wires, multiplexed trunk carrier systems and lately over digital optical fibre routes which carry thousands of calls over a pair of optical fibres. By applying the trunking principle the lines are only used for your call and then returned to the resource pool when the call is terminated. All these principles of trunking are applied to a multi channel radio system. Engineering Department

5 Sistema Convencional de Radio
Logica Individual Moviles Repetidoras Tone Panel Canal 1 Bloqueados y Monitoreando IDLE Tone Panel Canal 2 Canal 3 Tone Panel Consider a conventional two way radio systems where generally radios are allocated a specific channel in talk groups or clusters of talk groups using private Line signalling (PL). The main problem with this type of operation is that if one talk group is using the channel then it will block access for use by other talk groups on the same frequency. Often interference occurs in this situation with the other groups breaking into conversations causing a breakdown of general order on the channel. Also where there are a number of channels being operated from the same site independently Bloqueados y Monitoreando Canal 4 Tone Panel Engineering Department

With the use of modern microprocessor technology which has fast operating speeds and reliability the design of advance switching controllers have become very cost effective. It is now standard manufacturing design to include one of these advanced type of processors in every trunked type of field radio. By application of clever software controls these controllers can perform a number of functions which not only will control the subscriber radio fleet but also provide automated system management functions as well. The radios can also switch channels in milliseconds under control of the controller which give the ability of a user to have almost instant access to a free channel. In the basic trunked system a controller is fitted with a number of base stations and a number of directly connected dispatcher telephones. By applying the similar scenario Engineering Department

25 Llamada a la red publica (PSTN)
20 When call to a PSTN connection is requested the caller dials in the PSTN number preceded by a ‘0’. This preceding ‘0’ identifies to the radio that the call request is to a PSTN number. This ‘0’ is removed by the radio encoding software and encoded as a RQS PSTNI type call request. The system controller checks for authorisation and if permitted recalls the caller and obtains the dialled digits in a set data type MPT1327 telegram. If outgoing calls from the PSTN connection are permitted by the network the PSTN caller is required to dial the whole prefix, fleet and indent of the called party. The system controller verifies the requested number is authentic and approved prior to AHOYing the user. “ ” MPT System PSTN Engineering Department

26 Llamada a la red privada (PABX)
20 4312 MPT System If the network is connected to a local PABX then the calling sequence is similar to a PSTN type call. The exception is that the call is preceded by an ‘8’ which identifies to the system that the call type is a PABX or PABXI. If the dialled digits excluding the preceding digit are 4 digits then a PABX type request is made which includes the 4 numerical digits in the telegram. If the dialled digits are 5 or more up to 9 digits the a PABXI call request id made with the digits being requested by the controller in a data type telegram after authorisation checks are made.

Prefix No. 201 Fleet No. 3550 44 Prefix No. 201 Fleet No. 2001 20 “355044#” When an inter-fleet call is required the fleet number and ident of the called radio is dialled. This number, which can be either 6 or 7 digits depending upon the fleet size, is encoded by the radio and transmitted to the system controller. The controller then verifies that the caller is authorised to make inter-fleet calls and connects the caller to the called party if allowed. MPT System Engineering Department

33 Llamada entre Prefijos (entre tipos de usuario)
Prefix No. 203 Fleet No. 3550 44 Prefix No. 201 Fleet No. 2001 20 When an inter-prefix call is required the prefix, fleet number and ident of the called radio is dialled. This number, which can be either 9 or 10 digits depending upon the fleet size, is encoded by the radio and transmitted to the system controller. The controller then verifies that the caller is authorised to make inter-prefix calls and connects the caller to the called party if allowed. It may be possible that the fleet number and ident are similar as the calling part but this similarity is ended by the different prefix number. “ #” MPT System Engineering Department

34 Mensajes alfanumericos preprogramados
con teclado del radio, empleo de Mensajes Cortos Preprogramados (STATUS) en CC, tipicamente hasta 10 mensajes distintos Nota: CC= Canal de Control CT= Canal de Trafico 44 20 Status calls are only permitted between users in the same fleet. The call sequence is performed on the control channel without any need to switch to a voice traffic channel. The radio detects the operation of the ‘S’ status button and encodes the service request to the controller as a status call. The called ident and the status number is stored in the radio display with an audible repeated alert. The status message will remain until cleared by the called party. It is possible to store more than 1 status messages in a radio and the user can scroll through then clearing each message using a clear button. In the 1200 series radio it is possible to store text related status messages so that when a status message is decoded a specific related message is displayed. All numeric status messages can be interpreted by the called and caller if they both are utilising a common known directory. “44S03#” “Regresa al taller” MPT System Engineering Department
