Data sheet subject to change without notice RDPS-MF051(R1)10/01/2002 SHEET 2 OF 11 Product Specification MF600SWI 1. Introduction: The in-Line Micro 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 low pass filter provide protection from ADSL signal which may impact through non-line or other effects remote devices(handset, fax, voice band modem etc)and central office operation . For ADSL signal , it also provide protection from the high frequency transient and impedance effect that occur during POTS operation(ringing transients , on-hook,off-hook transient and so on). Because the POTS splitter connects directly to the subscriber loop media , it must also provide some protection for externally induced line hits or faults which could damage any attached equipment or endanger humans 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 pots splitter to protect against line overstress which could damage the splitter itself. 2.

The ZHP-r is valid only for voice band frequency. The combination of capacitors in the ZHP-r is only representative. The input shall be 27 nF however derived.

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 tip-to-ground and from ring-toground 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 M. 5.5. Test methods : 5.5.1. Off-hook insertion loss : The insertion loss of a device connected into a given transmission system is defined as the ratio, expressed in dB, of the load power available ( before and after insertion ) delivered to the output network beyond the point of insertion at a given frequency. In general, the insertion loss is defined as the ratio, expressed in dB of the power delivered to a load with the circuit in place and the power delivered to a load without the circuit in place. The added insertion loss shall be measured using the test up in figure 2. For measuring POTS band insertion loss for single filter module also for single filter with four added parallel load filters. General Insertion loss equation can be expressed as follows. Insertion loss = 20 log V2 / V1 dB where V1 = the measured voltage value of load without LPF in circuit. V2 = the measured voltage value of load with LPF in circuit. The test setup is shown in drawing below. Figure 2.

Return loss: Return loss measure the amount of energy that is lost due to reflection which resulted from impedance mismatching at the interface. Return loss is essentially defined as the ratio of the power incident upon a given transmission system to the power reflected caused by impedance mismatch with respect to reference impedance at the interface between source and device. Return loss figure are a function of the impedance of the circuit involved and are therefore frequency dependent. These impedance must be closely maintained in order to reduce the possibility of undesirable reflection and echoes which in long distance circuit the telephone user or destroy the data being sent. To perform the return loss test, open, short, load calibration must be done prior measurement while the LCR impedance analyzer being selected in impedance mode. Return loss is general expressed in decibels. General return loss equation is as follows. Return loss = 20 log ZL + ZM / ZL - ZMdB Where ZL = the reference impedance ZM = the measured impedance The test setup is shown in drawing below. 5.5.2.1.
