6.Installation and Connection

The condition for installation

The terminal asks for 110~220V AV power supply .It must be installed in the area where the network can cover. The strength of signal can affect the quality of voice.

Insert the sim card to card holderInstall antenna, In order to ensure the voice quality, antenna should be put beyond 1.5m from fixed phone and GSM FWT.

Connect the fixed phone and GSM FWT with the telephone line.

Connect the adapter and turn on the power button

1)      The installation for connecting to fixed phones

Notes: Bcs there are may types of fixed phone and their electric parameters are different, in order to avoid mutual disturbance between telephone and terminal and affect voice quality, the distance between phones and terminal is 1.5m at least.

2)      The Installation for connecting to billing device for metering

If the users demand to register cost during calls,billing device can be connected between terminal and fixed phone.Billing device register cost according to the anti-polarity signal that is provide by terminal.

3)      The installation for connecting to PBX for call extention

If users want to connect small PBX to this GSM FWT, connect terminal’s phone port to the PBX.

4)      The installation for connecting to VOIP gateway for call terminal

Suppose a VOIP call originated from US, which was transferred from US to china server on VOIP, finally the call will be terminated from internet to GSM network and to be sent to the destination answer side.

5)      The installation for connecting to alarm system for security
