Detailed Specifications

Netgear CM2050V-100NAS DOCSIS 3.1 2.5Gbps Voice Cable Modem

Overview 

The Netgear CM2050V-100NAS is a high-performance DOCSIS 3.1 cable modem engineered for environments requiring multi-gigabit internet delivery and integrated telephony services. Designed specifically for the Xfinity network, this unit serves as a critical edge device for remote offices, small businesses, or high-demand residential setups where Xfinity Voice is a core requirement. By utilizing DOCSIS 3.1 technology, the CM2050V supports downstream speeds up to 2.5Gbps, effectively eliminating the throughput bottlenecks often found in standard 1Gbps hardware.

In a deployment context, the CM2050V acts as the primary gateway between the ISP’s coaxial infrastructure and the local network. The inclusion of two RJ-11 telephone ports allows for the consolidation of data and voice services into a single hardware footprint, simplifying cable management and reducing power consumption at the site. The hardware features a 2.5GBASE-T Ethernet port, ensuring full compatibility with high-bandwidth routers and firewalls. It supports 32x8 channel bonding for legacy DOCSIS 3.0 connections while leveraging 2x2 OFDM/OFDMA for modern 3.1 efficiency. This architecture ensures low latency and high reliability for VoIP, video conferencing, and large-scale data transfers. As a dedicated modem, it provides a clean handoff to downstream networking equipment without the complexities or security overhead of integrated residential gateways.

Key Features

- DOCSIS 3.1 technology for multi-gigabit throughput.
- Integrated 2.5Gbps Ethernet port for high-speed LAN.
- Two telephone ports supporting Xfinity Voice services.

Frequently Asked Questions

Does this modem support Wi-Fi or routing functions?

No, the CM2050V is a dedicated cable modem. It does not have a built-in Wi-Fi router or DHCP server. You must connect it to a separate router or firewall to provide connectivity to multiple devices.

Is this modem compatible with all cable internet service providers?

The CM2050V is specifically certified for Xfinity by Comcast and is required for users who want to maintain Xfinity Voice landline services. It may not be compatible with other cable providers; always verify with your ISP before deployment.

Why is the 2.5Gbps Ethernet port significant for this model?

Standard Gigabit (1Gbps) ports cap actual data transfer at approximately 940Mbps due to overhead. The 2.5Gbps port allows the modem to deliver the full speed of multi-gigabit internet plans to compatible 2.5G or 10G routers.
