Drop-in Replacement Amp
dB-troncis launched its new dB-III, a drop-in replacement amp for Scientific-Atlanta System Amp II and System Amp III amplifiers. It is available in 870, 750 and 550 MHz configurations. The new amp, which utilizes GaAs technology, features several design improvements. For example, dB-tronics reports that the 870 MHz version will extend bandwidth to a minimum 870 MHz (typically 910 MHz) while lowering the current drain by approximately 30 percent and keeping the price equal to a remanufactured unit.
By using the dB-III, cable engineers can extend a 750 MHz system to 870 MHz without modifying the housing lids, and the amp uses all standard 550 or 750 MHz plug-ins. An on-board voltage monitor will alert the technician if the DC voltage drops below 22 volts. The dB-III is manufactured on a single circuit board, which can be configured by the factory as a high-gain, low-gain or unbalanced-triple. (dB-tronics, 800-356-2730, www.dbtronics.com)
Status Monitoring Transponder
Electroline developed a new DOCSIS-HMS transponder technology (DHT) for managing, monitoring and controlling HFC network devices. Designed to report critical status and performance information to a remote or centralized manager monitor, the transponder’s main function is to control, alarm and manage HFC equipment in the outside plant, whether the transponder is installed inside HFC equipment such as standby power supplies, fiber nodes and optical amplifiers or as stand-alone independent network test points (end-of-line monitors). The design is based on the combination of three standards: (1) DOCSIS for the PHY and MAC layer protocol; (2) SNMP; and (3) SCTE Hybrid Management Sublayer spec. Electroline says this approach uses existing DOCSIS cable modem facilities as the communications channel, which alleviates the need for specialized hardware controllers and modems at the headend. Additionally, it eliminates the need to reserve a downstream and upstream RF channel to carry the communications between the managed device and the headend.

QAM Integration for VOD
BigBand Networks unveiled its VOD Edge platform, which integrates dense quadrature amplitude modulation (QAM) and RF upconversion with the company’s Broadband Multimedia-Service Router (BMR). BigBand VOD Edge terminates gigabit networking onto the cable hybrid fiber/coax network. This takes advantage of BigBand BMR’s gigabit Ethernet protocol conversion, and its new card with QAM-modulated, RF-upconverted outputs. The QAM card’s density leverages the BMR’s media processing to conserve power consumption and headend space.
BigBand says that further space advantages are derived by combining the BMR’s integrated high-speed switching with QAM, which also streamlines network configuration for even greater cost-effectiveness and ease of use. Media processing at the network edge also drives de-jittering, which the company claims assures video transmission without compromising viewing quality, even when transported from centralized VOD servers via complex IP interconnects.
