In the event of vocal alarm, in which type of telecom network must Alert be integrated ?

 

Analogical


The analogical network is the most widely used, but the least reliable in the long term. Recently, the analog modems range embedding the vocal server feature needed to transmit vocal alarms has shrinked significantly, moreover there has been the great degradation of these products’ quality. Micromedia now advises that the analogical mode should not be used insofar as the durability of associated products is seriously threatened. Indeed, in the long term, there is no guarantee of being able to find products for replacing the present modems on the market. Furthermore, Micromedia strongly discourages the of analogical mode for vocal alarms transmission.
Even if the user has an analogical network, it is sometimes easily feasible to bring a digital line into the analogical autocom. It is a good idea to estimate the cost of bringing in a line or migrate to digital, regardless of what is finally decided.
If, despite everything, the analogical network remains the only solution, the references for modems tested by Micromedia are:

 

Digital (ISDN / RNIS)


Micromedia recommends this digital mode, which, unlike the analogical mode, gives guarantees in terms of durability and reliability. Moreover, digital is distinguished from analogical by a better transmission quality, much faster, and with a greater capacity for carrying out several communications at the same time on the same line.

TCP/IP

The telecommunication system via network is the solution for the future. It will develop on account of its almost complete flexibility of communications in this case. It is also distinguished by its low cost price. You can use the voice over IP (VoIP) integrated in Alert. The only restriction is to call IP phones and/or PABX compatible with the sip protocol.
