Recently we came across the project where FXS/FXO analogue phones should be sent over IP/Ethernet network, and solution with IP phones and gateways for several reasons could not be implemented. What we needed to offer, was a simple converter schemes, which will pass through all – CLI’s, DDI, and PABX specific protocols just like a simple converter. Also faxes should be working. In VoIP as we all know, faxes are usually problem, and some specific protocols implemented at PABX’es also sometimes does not works on VoIP.
Here is how you can do that using our products:
it’s an easy way to get 30 voice lines tranparently through the IP.
You need:
1 pair of AN-E1-Muxlite: https://www.ad-net.com.tw/index.php?id=254
1 pair of AN-E1-TDM-IP: https://www.ad-net.com.tw/index.php?id=491
If more than 30 lines should be sent over IP, you can use, 2E1, 4E1, 8E1, or 16E1 TDM over IP units. Each E1 line will carry 30 phone likes, so in case of 16E1 unit you can send over IP 480 phones.
In case even bigger capacity is needed, TDM over IP units can be cascaded to get more capacity.
