Description
Technical Specifications
The Casa Systems C1G Cable Modem Termination System (CMTS) is a new class of cable edge device that implements all of the DOCSIS 3.0 features enabling service providers to cost effectively offer highly scalable broadband services such as IPTV, video-over-IP, interactive gaming, as well as traditional broadband access and VoIP services.
Due to its extremely compact size (15 in x 8.75 in x 1RU), the C1G can be easily deployed in locations such as Multi-Dwelling Units (MDU), hotels and motels (hospitality), and small hubs.
