Chapter 16: Throughput Testing
The throughput test function measures the upload and download speeds of the DS2831’s cable modem
function. (See Chapter 15: DOCSIS 3.1 Cable Modem.) Throughput has two modes. 1G and 3G. These
support maximum test speeds of 1Gbps and 3Gbps links, respectively.
This mode requires a PC and Deviser’s speed test companion software, which is included with the purchase
of the DS2831 Throughput option. Contact your Deviser service representative for more information.
Throughput test
To conduct a throughput test, follow the instructions below.

Deviser offers a speed test software to assist Throughput. Using a PC installed with the software, deploy
the speed test server on the CMTS side of the CM link. Configure and launch the software according to
