Sunrise Telecom Introduces Cable Modem System Analyzer - Hukk Engineering Division - Brief Article - Product Announcement

ISP Business, Nov, 2000

Sunrise Telecom's Hukk Engineering Division, a pioneer in the digital CATV test equipment field, announced the new CM1000 cable modem system analyzer, which for the first time allows technicians to test the performance of cable modems. Initial orders for the CM1000 have already been received from the top three CATV cable modem providers in the US.

Until now, cable modem installers have had to use the shotgun approach to installation. That means replacing all components, including the drop cable, splitters, and internal wiring because there is no reliable way to test performance of the installation.

The CM1000 can prevent the costly, time consuming, and often unnecessary practice of replacing equipment and wiring to the street by checking the various points in the installation, allowing the technician to quickly determine which components needs to be replaced.

The CM1000 is based on a modular platform allowing future modules to perform different jobs. Technicians will only need to swap out a module and the instrument will perform completely different tests making the instrument future proof as different standards and requirements arise. In addition, with the CM1000's full color display, technicians can determine at a glance whether the connection meets the requirements.

Simulating a cable modem, the CM1000 communicates with the cable modem termination system (CMTS) to characterize the digital performance in both directions. In addition to conventional digital tests such as MER, BER, level, and constellation on the forward path, a new Hukk technology allows block error rate (BkER) testing on the return path without a headend unit.
