The ONT Comtrend GRG-4267uF is a dual band terminal, works in the two bands, 5G and 2.4G band, in the 5G band it has IEEE 802.11 WIFI / n / a and in the 2.4G band it has IEEE 802.11 b / g / n. It has internal antennas and is MIMO 3 * 3 in the 5G band, in the 2.4G band it is MIMO 2 * 2.

The ONT terminals are user devices in the FTTH (fiber to housing) solutions of Comtrend, they admit access to ultra-wideband for residential users or small businesses (SOHO) that use GPON technologies.

The ONT of this family have POTS ports and GE Ethernet ports, which allows high performance transmission capabilities.

With the Felix application of Alea Soluciones, the configuration is automatic through the TR-069 protocol. The provision of the same is done through graphical interface at a very high level. It allows an effective provision of the services and commercial products that you have created as an operator for your clients. It allows to abstract from the low level of configuration of machines, systems or complex and heterogeneous environments. Felix configures the ONT at a high level with Data, Telephony and TV services, both IPTV and RF Overlay.
