ATX Networks launches MDU offerings
ATX Networks has a busy show schedule, including the announcement today of a new product offering designed to support the delivery of content into MDU and hospitality accounts, as well as new features for its digital video insertion platform.
On the MDU and hospitality fronts, ATX said its UCrypt platform is a clean and simple, "no set-tops required" solution that transitions HD and SD content on the existing HFC network to Pro:Idiom-encrypted – or in-the-clear – content. UCrypt can also support various output formats, including QAM and GigE. ATX said it was in the process of expanding the UCrypt product to include a bulk QAM-to-analog solution.
ATX is also displaying its DVIS, DVISm "Mini" and new DVISn "Nano" MDU product offerings, which are integrated encoding, multiplexing and QAM transmission product offerings optimized for any digital content insertion at MDUs.
New features for the DVIS and DVISm products include RF bypass switching capability, as well as an advanced PID monitoring algorithm. ATX said the new features were geared toward ensuring reliability of service for add/drop applications. The DVIS can encode from one to 10 programs, and the DVISm from one to four.
Both products are provided in an MDU hardened wall mount cabinet and include integrated RF management and a digital channel deletion filter. ATX said the level of scalability and integration provided in the DVIS and DVISm allow them to be configured for any digital insertion method, including add, add/drop or drop on an existing QAM, QAM deletion and re-insertion, or QAM insertion at the band edge. An IP-based management port with on-board Web server and SNMP support allows users to configure and monitor the DVIS or DVISm from a local or remote location.
A GigE output card – with SFP cage – is also being added to the DVIS and DVISm product offerings for applications where users find it more appropriate to deliver encoded content over an IP network.
ATX is also demonstrating its new DVRT 1RU headend unit, consisting of an integrated demodulator with ASI, IP and baseband A/V outputs. It can be used in conjunction with the DVIS or DVISm in order to accommodate backhaul of local audio/video content in or above the return, thereby eliminating the need for a dedicated fiber. The backhauled content can then be retransmitted from the headend, in digital or analog format, to a specific node or select group of nodes requiring the content.
ATX is also introducing the DVISn product, an ultra-compact and cost-effective digital insertion appliance available in single- or dual-channel versions. The Nano is geared toward applications requiring a basic and cost-effective QAM insertion into an empty EIA channel or at the band edge.
Lastly, ATX is showcasing its DigiVu multichannel MPEG-2 encoder/multiplexer with QAM/GigE output.
DigiVu is a line of compact and flexible audio/video encoding products for digital transmission and/or insertion applications. ATX said the cost-effective and space-efficient encoding, multiplexing and transmission platform is ideal for digital simulcast applications or for digital delivery of PEG or hub site-specific programming.
Meanwhile, with an eye toward letting MSOs upgrade their unsupported legacy equipment without removing it from the field, ATX Networks said its HFC Enhance offering of drop-in upgrade modules for amplifiers and nodes saves operators not only time and money, but also allows for a network upgrade with minimal customer downtime.
ATX’s lineup at Expo includes:
- Return path transmitter conversion: ATX offers MSOs the ability to cost-effectively and efficiently convert FP-based return path transmitters to DFB-based transmitters in order to obtain improved optical link performance, and therefore support an increased number of carriers in the return band and/or support higher QAM modulation formats, including 64 QAM, necessary for services such as DOCSIS 2.0 or 3.0.
- Node segmentation solutions: The HFC Enhance Node Segmentation product offering brings to market a suite of products that provides MSOs segmentation options for legacy nodes, including the ADC/C-Cor ISX-30XX, the Scientific Atlanta 6920 and 694X, and the Motorola BTN legacy nodes.
- Drop-in amplifier upgrade modules: The HFC Enhance product line offers the QPAL and QFLAME drop-in upgrade modules, which allow for a bandwidth enhancement of the Texscan/Jerrold/GI/Motorola line extender and the Texscan/Arris/Antec trunk/mini-bridger amplifiers, respectively. Just released is the QC900 series of drop-in upgrade modules, which allow for a bandwidth enhancement of the C-Cor 900 series line extenders and trunk/bridger amplifiers.
And ATX has added QAM narrowcast amps and high-density return path receivers to its Maxnet II Platinum Series.
With the deployment of DOCSIS 3.0, and in particular with M-CMTS implementations, the narrowcast network has added combining layers, which in turn make it more difficult to deliver narrowcast signals to the transmitter with enough level. ATX said its Maxnet II QAM Narrowcast amplifiers provide the extra gain necessary to meet the transmitter input requirements.
The amplifiers come in a variety of offerings, including dual 12 dB gain, lossless 8-way narrowcast combiner with passive broadcast insertion, as well as a lossless 8-way narrowcast combiner with high level output test port. A redundantly powered, three-rack unit chassis can hold up to 20 functional modules, allowing for the ultimate efficiency in terms of rack space utilization.
ATX’s latest Maxnet II return path receiver design incorporates an integrated eight-way splitter into the receiver modules and provides the ability to attenuate the RF outputs on a per-port basis. ATX said 20 receiver modules can be accommodated in a redundantly powered three-rack chassis.
