05/07/2009 6:04 PM

Good Day Global Spec Team. First I want to thank you for your kind attention for all news letters every day and keep me up with news technologies from many Innovations and discovers from our times. Today appear for new examination, one project, what I must represent with Schematic Diagram for Intercom Office communication. For explain clear what I need, I would like to present this facts: I have one Central Intercom were it is connected, 4 Bureau Office. First Office bureau it's belong to Director, second Office bureau to Engineer Chef, tirth Office bureau belong to Sr. Accounting and fourth office bureau, belong to Administrator. This 4 people must communicate with Central Intercom with access priority like this; when Engineer chief it is in communication with Sr. Accounting, but if Director want communicate in same time with Sr. Accounting because of priority for Director, Central Intercom disconnect Engineer temporarily from communication with Countable and pass immediately Director to communicate with Sr. Accounting. When Director finishes communication with Sir Officer, Central Intercom pass immediately connection again to Engineer from temporarily interruption to communication with Sr. Accounting. So, this Central Intercom it's made for give to Office people, Hierarchic Priority Communication. I would like to have your help for one of this solutions: what processor and auxiliary circuits integrates can I found with your help, or if is possible to help me with most simple Schematic Diagram what can represent one Central Intercom Office with Priority communication. In hope for understanding my interest for Schematic Diagram of this Central Intercom I would like to present all kind respect and cordiality attention, Mihai.

it is so easy,

we can only make "special" line for Director to make a call with every one.By making

his Push button can disconnect all of line.and make connection as per number that he

wants to.

But one thing that must be understanding is when Chief Engineer is talking with Sr. A

accounting and suddenly the communication is disconnect because Director pushes

the line for Sr. Accounting,and why Chief Engineer must wait for along time (Hold

Mode)until director Finnish his communication with his Sr. Accounting ?

I imagine he is waiting with classic music waiting for his Director Finnish, meanwhile

may be at that time he is needed in someplace to do something.

Here in the USA we call that homework. If we supply you with a schematic for your school project you will only learn how to ask others to do your thinking for you.

If you presented YOUR schematic to the group for examination you would find people very helpful. But first you must think through the design yourself.

The system we use in the west is called "an in-house telephone system" with Caller ID display, call waiting, answer phone and "call-Back" etc etc.....

It does not need to be designed, it can be bought exceedingly cheaply and has the added advantage that it can also be connected to the public network if required.

Intercoms have mostly gone the way of the Dinosaur in the west......thank God!!

Thank you very much ethobil for your attention. I choose one of this link and combine with another's schematics parts and with my modification of wire diagram and some electronics components, I design in my own way what is necessary present to school. It is not a project for finally school, it is pre finally or something like that. Thank you again and all the best for you, mihaitechnic.
