Introduction: The In-Line 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 1.5 Mbps downstream and 512 kbps 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 premise based POTS splitter. Recent field trials of ADSL Lite equipment jointly carried out by a group of manufacturers and a North America network operator has proved the technology, achieving maximum data rate for distance up to 15000 feet, 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. The In-Line filter for phones or telephone equipments sharing a two-line phone jack. The low pass filters provide protection from ADSL signal which may impact through non-linear or other effects remote devices ( telephone sets, facsimile machine, answering machine, voice band modem, etc. ) on line 1 and line 2. For ADSL signal, it also provides protection from the high frequency transients and impedance effects that occur during POTS operation ( ringing transients, on / off hook transients and so on ). This In-Line filter provides one filtered jack for any single or two-line phone devices. Because the In-Line filter 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 equipments or endanger humans interacting with the installed equipments. The circuit protection will be provided mostly by standard central office line protection means and additional protection measures built into the In-Line filter to protect against line overstress which could damage the In-Line filter itself. The electrical and transmission specifications are designed to meet T1E1.4/2001-007R3 and as per customer’s requirement.

On-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 setup in figure 1. 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. Zon definition: 1.0 nF 5 Mohms Figure 1.

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 Z L = the reference impedance ZM = the measured impedance The test setup is shown in drawing below. 4.5.3.1.
