What details should be paid attention to when selecting the functions of the tube corridor fiber phone

Many merchants are now doing tricks on the tube corridor fiber phone. Many manufacturers are cutting corners. Although it has the function of the tube corridor fiber phone, these functions have been cut to a certain extent, and it seems that you can make calls. However, the number of simultaneous calls is not up to a certain standard. Here, 800 Tong Smart will show you how the details are:

meet the standard:

The construction location of the pipe gallery determines that the mobile phone cannot be used here, so the fiber phone in the pipe gallery is the only tool for external communication. It should exist as a communication guarantee system, which determines that the pipe gallery fiber phone cannot be used. Equal to other industrial telephones or emergency telephones, the tube corridor optical fiber telephone must not only realize free calls to the various extensions in the corridor and to the center, but also freely communicate with users of the public network outside the corridor. Not only must they be able to make calls independently, but also It is also necessary to allow free calls from outside public networks to come in. This will effectively provide the normal work efficiency of operation and maintenance personnel, and can also play a role in communication protection under special circumstances.

Things to note

One thing to note here is that some manufacturers play side-by-side shots. They only mention that their products can realize the function of external calls, but they don’t mention how many phones can talk at the same time, that is, how many external lines their system can receive. There will be several or more than a dozen units entering the corridors of some pipe corridors. Taking into account the special circumstances during rescue and disaster relief, 1, 2, or 3, 4 external lines are obviously not enough. Especially for some star connection schemes, the main unit and the auxiliary unit are completely a telephone. The function of the auxiliary unit is to extend the receiver, microphone and dial keyboard of the main unit. The main unit and the auxiliary unit use a number source. If a phone is talking, other phones can no longer be used, and calls coming in from outside can only be answered on the main unit, and the auxiliary unit cannot answer the call. These need to be paid close attention to by pipe gallery users when purchasing.
