Description
The concept of Best Value is to offer customers the best value product, sourced from a variety of manufacturers all over the world, in any given category, at any point in time. The products selected for our Best Value range are carefully evaluated in terms of price, performance and manufacturing quality before they make it onto our website. Although certainly a 'value' brand, Best Value products are never inferior quality... just superb value for money.
Description
The M-ADSL-FILTER has been specifically designed to implement the functionality of low pass filter in G.Lite system.G.Lite technology is similar to full rate ADSL in using DMT technology but operates at a lower data rate of up to 1.5Mbps downstream and 512Kbps upstream, depending on line conditions and lengths. ADSL Lite is proposed as a lower speed version of ADSL that will eliminate the need for telecom to install and maintain a premises based POTS splitter. It was found necessary to include one or more low pass filters in series with the POTS terminals in order to reliably achieve maximum data rates.
For POTS voice band service, the M-ADSLFilter provides protection from ADSL signals, which may impact through non-line or other remote devices (handset, fax, voice band modem etc) and central office operations. For ADSL signals, it also provides protection from the high frequency transient and impedance effect that occur during POTS operations (ringing transients, on-hook, off-hook transient and so on). Because the POTS splitter in the M-ADSL-Filter connects directly to the subscriber loop media, it also provides some protection for externally induced line hits or faults which could damage any attached equipment or endanger people interacting with the installed equipment. The circuit protection will be provided mostly by standard central office line protection means and additional protection measures built into the POTS splitter to protect against line overstress, which could damage the splitter itself.
DC CHARACTERISTICS
All requirements of this specification can be met in the presence of all POTS loop currents from 0 mA to 100 mA. This Single In-Line filter can pass POTS tip-to-ring DC voltages of 0 V to 105 V and ringing signals of 40 Vrms to 150 Vrms at any frequencies from 15.3 Hz to 68 Hz superimposed on DC voltages in the range from 0 V to 105 V. The DC resistance from tip-to-ring at the line port interface with the phone interface shorted, shall be less than or equal to 50 ohms for one filter. The DC resistance from tipto- ground and from ring-to-ground at the Phone interface with the Line interface open shall be greater than or equal to 10 Megohms. The ground point shall be local building or green wire ground. As an objective, the DC resistance should exceed 10 MW.
