What is the technical difference between the MVP110-EURO&MVP120-EURO?

The MVP110 only supports the FXS interface, while the MVP120 only supports the FXO interface. What this means is the MVP110 can only be used when connected directly to PBX/KTS Line or CO port, an analog telephone or fax machine. The MVP120 would be used if you intend to interface the voip with a PBX/KTS Station Port or PSTN phone line. Go to our web site for our latest manuals at:
