Dinstar DWG2000F-8G-M

Dinstar DWG2000F-8GSM-M is an eight-port GSM gateway of modular design with a built-in antenna combiner. Speaking about the model, DWG2000F-8GSM-M is worth highlighting the ability to increase the number of supported SIM cards from 8 to 16 by simply purchasing an additional board. The upward opening slot for SIM cards makes it easier to replace them without dismantling the device. These gateways are fully compatible with Dinstar SIMCloud/SIMbank solutions and are easy to operate.

Dinstar DWG2000F-8GSM-M is a corporate eight-port VoIP GSM gateway, the use of which allows medium and large companies to save significant money. The savings are achieved due to the ability to connect to eight GSM lines via the SIP protocol to the PBX installed in the office. The upward opening slot for SIM cards makes it easier to replace them without dismantling the device. These gateways are fully compatible with Dinstar SIMCloud/SIMbank solutions and are easy to operate. Speaking about the DWG2000F-8GSM-M model , it is worth highlighting two important advantages. Firstly, it is the ability to increase the number of supported SIM cards from 8 to 16 by simply purchasing an additional board. Secondly, it is the presence of an antenna input divider, which reduces the number of antennas used by four times without losing the quality of reception and transmission of a cellular signal.
