Key Features

• Access to Fiber Optical Network: Supports downstream 2.5Gbps and upstream to 1.25Gbps with a transmission distance of up to 20km. Higher bandwidth support makes it possible to both integrate and provide more additional services.
• Easy Remote Management: GRG-4242u supports the ONT Management and Control Interface (OMCI), making it easy to configure, activate and manage remotely from an Optical Line Terminal (OLT).
• VoIP (SIP): Voice over Internet Protocol provisioning communications services rather than via PSTN.
• Remote Management: TR-069 / TR-181 standard data model for the ISP remote control.
