DOCSIS is considered by many as the reason why the cable industry can keep up with the rapid pace of end-users’ hunger for faster and faster Internet speeds.
Data Over Cable Service Interface Specifications (or DOCSIS, for short) is a telecommunications standard developed by CableLabs, the standard-setting organization for the Cable industry. DOCSIS has been adopted by Cable Operators worldwide thanks to its ability to enable high-bandwidth data transfer through an existing coaxial cable system initially designed for cable TV (video) transmission.
But with the growing prevalence and demand of high-speed fiber-optic internet, cable networks face a serious challenge that they have met by constantly evolving the DOCSIS standard. This has allowed them to remain in the market and improve their service offerings. With each advance in the DOCSIS standard, from the original DOCSIS 1.0 to DOCSIS 3.1, the current standard (and DOCSIS 4.0 in the future), the cable industry pushes the limits of bandwidth to maintain a competitive advantage. DOCSIS 4.0 promises to offer 10G bandwidth in the downstream and 6G bandwidth in the upstream, which helps combat the speeds of 5G Wireless and fiber-optic standards like XG(S)-PON!
|Feature||DOCSIS 3.0||DOCSIS 3.1||DOCSIS 4.0|
|Maximum upstream speed||200 Mbps||1.5 Gbps||6 Gbps|
|Maximum downstream speed||1 Gbps||10 Gbps (with the existing spectrum, but not existing architecture)||10 Gbps (with expanded spectrum)|
|Throughput||256-QAM (42.88 Mbps per 6 MHz channel)||4096-QAM (1.89 Gbps per 192 MHz channel)||4096-QAM (1.89 Gbps per 192 MHz channel)|
DOCSIS technology is used in many different types of devices. DOCSIS is used for direct internet access by a cable modem, or as a voice gateway for telephone, or even as a combined device with voice, wireless, and internet. It is also used in set-top boxes to provide Internet and video (TV) services, as well as being embedded at other points deep inside a cable network. DOCSIS offers some unique tools that allow network operators to use DOCSIS devices to help monitor the health of the network itself. It is the versatility and speed of DOCSIS technology advancement that has given it the longevity to last for over 20 years.
Promptlink offers only the very best when it comes to DOCSIS testing solutions and monitoring systems.

What Promptlink Can Offer
DOCSIS Network Monitoring and Provisioning
CPM provides a complete way to monitor issues happening in a DOCSIS cable plant. The PNM module helps proactively detect and correct impairments in the network before they impact end-users Quality of Experience (QoE). Network NoiseHawk detects and pinpoints where noise is entering the network, correcting issues that impact large numbers of customers. NoiseHawk narrows the problem down to a single network component or segment between two components.
This three-pronged approach provides proactive, reactive and historical troubleshooting to best conquer the unique challenges on an HFC DOCSIS cable plant. Only Promptlink can offer this versatile solution to the most pressing issues managed in today’s DOCSIS cable plant.
DOCSIS CPE Testing Solutions
Cable operators, testers or 3PL companies looking for an innovative testing solution for the functionality of their DOCSIS CPE devices can find it in Promptlink’s CPE ATLAS.
CPE ATLAS is a next-generation SNMP-based CPE testing tool that can support up to 20 CPE devices of any kind in any combination, all tested in parallel:
- Cable modems, including voice and wireless cable modems
- DSL devices, including voice and wireless DSL devices
- GPON/XGS-PON modems
- Wireless routers
- Wireless extenders
- Powerline devices
CPE ATLAS enables testing and verification on any such devices in much higher volumes than the original industry standard CMTP and the competition, cutting down costs tremendously. Promptlink’s shielded enclosures provide accurate Wi-Fi test results in any environment.
Why Promptlink Is the Right Choice
Promptlink’s testing solutions enable companies to streamline their testing process and reduce costs as a result. The CPE ATLAS has been designed with a few key features in mind:
Fully Automated testing
Repeatable and Reproducible
High-Volume Testing Capabilities
