The DG3450 Wireless Gateway supporting DOCSIS 3.1 allows unprecedented data rates to be delivered to MSO customers. The DG3450, along with its 4×4 802.11ac Dual Band Wireless radios, offers superior Wi-Fi performance enabling video over Wi-Fi.

The MoCA2.0 interface with channel bonding enables the creation of a high performance home network. The switchable US diplex filter is designed to produce superior RF performance and ease of deployment on a DOCSIS 3.1 network.

Increased DRAM, Flash and Multiple embedded processor cores are designed to allow new applications to be deployed on the gateway. This feature-packed unit is intended to serve as the hub of the subscribers network, connecting all IP capable devices (Internet, Data and Video) throughout the customers premises.

Residential gateway support has always been a concern of the operator. The DG3450 distinguishes itself with capabilities to minimize these support needs. Multiple provisioning methods (SNMP, Configuration File, Remote WebGUIaccess, TFTP, and TR-069/181) allow custom designed setups to be applied to monitor the end user more efficiently. Multiple remote access levels (User, Cusadmin, and MSO) also allow more ease and flexibility for manual configuration and control.

The DG3450 will help lead the future to advanced home and small business services.
