MASTERBUILT - Headends by Blonder Tongue
- Cable television has become a standard part of everyday life for the average person. Those familiar with the industry know that there are many differences in the equipment and method of which TV signals are delivered to consumers. It starts with the cable television headend, essentially the heart of the CATV system. The headend is a significant investment and Blonder Tongue believes that sacrifices should never be made when it comes to choosing the right headend solution. We pride ourselves on providing the finest professional quality CATV equipment at an affordable price. Blonder Tongue equipment is often imitated, but never duplicated. We don’t just sell equipment and are committed to provide our customers with the finest cable television solutions available.
Based on this philosophy, Blonder Tongue went back to the drawing board and refined our process of designing and building “pre-fabricated” headends for customers to create a program to lead the industry. MASTERBUILT Headends by Blonder Tongue has arrived.
The Blonder Tongue Communication Station CMTS unit is based on the DOCSIS (Data-Over-Cable-Service- Interface-Specification) standards. The CMTS features a scalable design architecture that supports one DOCSIS or Euro-DOCSIS downstream channel with 64 or 256 QAM modulation and up to eight (8) upstream channels that can be factory or field installed supporting QPSK or 16 QAM. The single rack unit (1.75” high) can be installed in a cable headend facility or a distribution hub site and can function with any DOCSIS/EuroDOCSIS certified CPE (Customer Premise Equipment) device.
