“Music trunk networks get their name nfrom. The world of telephony traditionally two cites nwould nwould bundle together their connections into a single thick line. Like the trunk of a nreferred to as a trunk line. And then the local household looped lines would be like the branches of a tree one line for each household.
The reason why trunking nhas become important is because it offers some huge advantages over conventional for larger agencies. A conventional system is a system that has dedicated channels dedicated to a specific nuser or group of users you select a channel manually by moving a selection knob on a radio or pressing some buttons or maybe. Using some kind of drop ndown menu in a display so conventional means nselecting. The channel in order to communicate.
So dedicated to particular users channel. One might be fire channel. Two might be fire chief s channel three might be animal control in order to communicate nwith these particular groups. A user has to make a nchannel selection first by hand manually conventional has some huge advantages why it s still popular naround.
The world today. It s very fast to setup. A call. It s easy to use and nit s pretty inexpensive.
However. There are some ndown sides as well remember conventional means using dedicated channels. Nthat are manually selected and when a channel is being used it s used exclusively by one caller. So anybody else who wants to nmake a call on that channel has to wait until the call is over it s an inefficient use of radio channels.
I mean think for a moment channel. One the fire channel you d expect to be busy all the time. But channel three the nanimal control channel well how many loose dogs are there that channel can go idle. So while you ve got callers waiting to have a crack at channel.
One they can t make use of channel three even though it s completely idle. If you wanted to add groups for example. You d have to add a new nchannel that they can select in a sense you re limited by how many channels you can select from manually and also adding a new nchannel or a new user group to this whole radio system means that you ll have nto go out and reprogram. All the radios all over again.
There is a bit of a trade off. I mean if you re a small nagency. A conventional system is absolutely perfect. If you know the groups that they are ngoing to be communicating with why not go for a conventional system.
But as soon as the number of groups. The number of users that nyou re working on a system increases. You might actually like to consider. Trunking.
Instead. Trunked radio. Might be better called computer controlled or ncomputer aided radio. A trunk user identifies another user or group of users they nwish to communicate with and a computer automatically assigns them the first free available channel from a pool of channels to make each call the underlying principle of trunking is that not all users or groups will want to communicate in na channel at the same time so there can be many more users or groups.
Then there are repeaters in the system. We can explain the difference nbetween conventional and trunking using the nsimple analogy from banking consider a conventional bank in which specific tellers are dedicated to specify types of customers for example you have a teller that deals with ordinary household users making cash withdrawals and deposits and then another teller nwhich is dedicated to business accounts. So what happens at lunch time. A long cue develops as household users want to make cash withdrawals.
Nor put in cash deposits. Then that teller is over loaded. Whereas the business teller finds one or two business customers. But most of the time stands idle.
This is the problem with nconventional systems by contrast. A trunking teller can serve any type of customer and do any sort of transaction so at lunch time when the long cue of household users wanting to make cash. Withdrawals or cash deposits is mixed in with the business users. The controller at the head of the cue simply assigns each customer to the first available teller this means a more even throughput of the transactions because the tellers are far more flexible and the trunking controller nat.
The head of the cue is an intelligent intermediary between the customers and the tellers. So that s the basic difference nbetween conventional and trunking networks in one. The users manually control the allocation of channels by selecting from a knob nwhereas in trunking systems. A computer at the center of the network is responsible for this ” .
