TERRA-FXOII is an IP telephone interface with 2 sets of telephone lines and DTMF management for receiving or broadcasting calls. The CH1 of TERRA-FXOII supports full duplex communication with AEC (Acoustic Echo Cancellation). It is suitable for the use with analogue and digital phone systems. The typical analogue phone application can be the conventional telephone line/cell phone to intercom/paging to a chosen TERRACOM device (or a device group) through TERRA-FXOII. In addition to the digital phone application, the TERRA-FXOII can act as a dial agent and allow the IP phone (AVAYA, CISCO & 3COM etc.) to dial DTMF keys and proceed intercom/paging with a chosen TERRACOM device (or a device group). The TERRA-FXOII can be easily congured via web interface providing full control over features such as read telephone line status (call in, ringing, disconnect etc.) and hang up Line 1/Line 2 manually or via 3rd party commands, pre-chime/post-chime/SIP call tone setting, scheduler & output levels.
