Touchstone® TG8442 Cable Voice Gateway

DOCSIS® 3.1 Gateway with 802.11ac Wi-Fi

ARRIS HomeAssure Enabled

The TG8442 Telephony Wireless Gateway delivers the gigabit broadband performance of DOCSIS 3.1. This feature-packed unit is intended to serve as the hub of the subscriber's home or business network, connecting all IP capable devices (Internet, Data, Voice and Video) throughout the customer's premises.

The TG8442, with its 4x4 802.11ac and 3x3 802.11n Dual Band Wireless radios, offers superior Wi-Fi performance enabling video over Wi-Fi. The TG8442 is ARRIS HomeAssure Enabled. When used with additional Wi-Fi Extenders, the solution delivers high-performance Wi-Fi to every corner of the home, while offering ease of use for the consumer and reduced OPEX costs for the service provider. The TG8442 gateway can provide automated network optimization, interworking with the self-configuring extenders, the HomeAssure consumer App and the HomeAssure Cloud management platform for remote management, analytics and diagnostics.

The switchable US diplex filter is designed to produce superior RF performance, surge protection and ease of deployment on a DOCSIS 3.1 network.

Optimized DRAM, Flash and Multiple embedded processor cores are designed to allow new applications to be deployed on the gateway.

The TG8442 is designed to minimize support costs with multiple provisioning and remote management methods (SNMP, Configuration File, Remote WebGUI access, TFTP, and TR-069/181). Multiple remote access levels (User, Technician and MSO) also allow more ease and flexibility for manual configuration and control.
