Motorola Introduces Node-Hosted CMTS Technology for Enhanced HFC Network Expansion

Strategic Insights

— 1 min read

Motorola, a leading provider of integrated communications solutions, has announced the introduction of its new node-hosted DBM-2000 distributed broadband module at the Western Cable Show 2000. The innovative technology enables operators to expand their existing HFC networks to meet the increasing demands of IP telephony and provides the potential for greater bandwidth per subscriber. By pushing CMTS functionality deeper into the network, Motorola's solution helps operators upgrade their networks with ease, ensuring seamless IP data delivery.

Key Takeaways:

  • Motorola's node-hosted DBM-2000 distributed broadband module is designed to push CMTS functionality from the headend deeper into the network, closer to the home/office, allowing operators to easily upgrade their networks to meet IP data delivery requirements.
  • The DBM-2000 builds a Layer 2 bridge with Ethernet-type baseband data network transmissions between node and headend, and RF transmission between node and the subscriber's cable modem over existing HFC plants.
  • The module supports both the Physical Layer (PHY) and the Media Access Layer (MAC) functions of a Layer 2 bridge in addition to the routing functionality of other Motorola CMTS products, enabling optical/electrical baseband media conversion, QAM modulator, RF upconversion, RF tuner/downconversion, and QPSK/QAM burst demodulation.
  • The DBM-2000 allows for the transfer of IP data via a PC, demonstrating its ability to support IP telephony and greater bandwidth per subscriber.
  • The new module can be factory configured or field installed in Motorola's STARLINE SG2000 node platform, providing flexibility and convenience for operators.

Statistics:

  • The DBM-2000 module supports 10/100 Mbps Ethernet and 155.52 Mbps FDDI data interfaces, ensuring high-speed data connectivity.
  • The module provides a physical layer (PHY) with QPSK/QAM burst demodulation, RF upconversion, RF tuner/downconversion, and optical/electrical baseband media conversion, enhancing its capabilities.
  • The DBM-2000 also features MAC functions, controlling the flow and routing of data traffic to multiple subscribers, enabling efficient network management.
