The combination of features and packaging offers extremely efficient use of board area, saving significant system size and cost, maximising time to market for Telephony Systems developers. The AG1460 has been designed to work with loop lengths of up to 3.0km (800 including telephone), with both resistive and complex line impedances. Its performance to regulatory standards allows use in public and private network applications. (c) Silver Telecom 2004 The AG1460 has integral dc/dc converter and ringing generation thus providing all the line powering requirements from a single supply. The SLIC requires a minimum of external components. The system interface has been designed for connection to all popular codecs of both the audio and signalling connections. The AG1460 is ideal for low line count, short loop length applications, such as ISDN Terminal Adaptors, Internet Telephony (VoIP), Computer Telephony Integration (CTI), Digital Loop Carriers (DLC), Wireless Local Loops (WLL) and Small Office Home Office (SOHO).

(c) Silver Telecom 2004 V1.4 May 2004 Data Sheet AG1460 QUAD 5V RINGING SLIC The battery feed to the telephone line is generated from the positive supply rail. This provides a -48V battery feed to the line, except during ringing, when this is increased to -72V. The loop current is pre-set to a constant 24mA. If the loop length is such that the constant current feed cannot be maintained (i.e. >3km), then the AG1460 will revert to a constant voltage source, allowing the loop to be serviced at a reduced loop current. 1.0 Line Interfacing As well as being in an electrically demanding environment, the needs of different applications and regulatory standards means that the SLIC must allow flexibility, together with facilities to ensure robust performance. All four of the SLICs on the AG1460 provide a complete and flexible interface to the telephone line. 1.1 Battery Feed The AG1460 has an integral DC-DC converter which generates the battery voltages in the device. This means that only a supply of +5V, and GND is needed, unlike conventional SLICs which will need a battery voltage of anything between -20V and -60V (-75V for ringing). This confers a significant cost, space and time to market benefit on the equipment designer. 1.2 Ringing The ringing signal is generated by switching the appropriate SLIC into ringing mode by setting the RM pin high and then toggling the F/R pin at the required frequency and cadence. The toggling of the F/R pin produces a balanced signal at Tip and Ring. These signal waveforms are shown in figure 3. During ringing the DC-DC converter automatically Condition 1 - DC operation Signal 1 0 Notes No ringing INPUT RM OUTPUT SHK 1 0 Off hook detected NOTE: SHK SHOULD BE DE-BOUNCED Off Hook Condition 2 - Ringing On-hook 1 Condition 3 - Ringing/Off-hook 1 sec 3 sec RM 1 sec 3 sec 0 1 F/R (input) 0 SHK 1 0 The phone goes off hook, and SHK is detected at point A (leading edge). RM must be switched low in <500ms (point B), and the ringing cadence should be removed from F/R.. As long as the telephone is off hook, SHK will remain high. A B Figure 3: Ringing Signal Waveforms (c) Silver Telecom 2004 V1.4 May 2004 Data Sheet switches to produce a battery voltage of -72V. This will produce greater than 40VRMS into a REN of 3. The slope of the edges on the ringing waveform is determined by the value of the slew rate capacitor connected between the CAP pin and Ground. A 220nF capacitor is recommended with 20Hz ringing. When the "off-hook" condition occurs during ringing, the ring-trip circuit on the AG1460 senses the loop current flowing and signals the off-hook condition on the SHK output (as shown in figure 3). The SHK signal must be "debounced" to remove any spurious pulses by the controlling processor. On detection of SHK the ringing signal must be removed from the F/R pin and RM taken to a logic 0 within 500ms to avoid excessive power dissipation in the line driver circuit. The ring-trip function will operate up to a maximum loop resistance of 800 (including telephone), which corresponds to around 3km loop length. To keep within the power rating of the on-board DC-DC converter, it is important that only one SLIC channel is ringing at any time. This can be met by using a ringing cadence of 1 second ON, 3 seconds OFF. The active ringing channel is then sequenced so that all four SLIC channels may be in the ringing mode, but only one is supplying ringing current at any one time. AG1460 QUAD 5V RINGING SLIC The DC-DC converter can be switched off by applying a logic 1 to the PD input. This reduces the current consumption to a nominal 10mA. The SLIC takes 50ms to power up from this powered down state. When using the power down state it is recommended that the SLIC is polled (powered up periodically) to check for SHK (the subscriber has gone off hook). Since the DC-DC converter supplies the power to all four SLICs on the AG1460, all four SLICs will be powered down when the PD signal is applied. 2.0 The 2-4 Wire (hybrid) Conversion. Each individual SLIC of the AG1460 transmits and receives balanced 2-wire analog signals at the Tip and Ring connections. These are converted to a ground referenced output at VOUT and from a ground referenced input at VIN. VOUT and VIN are normally connected to a Codec for conversion to and from a digital Pulse Code Modulated (PCM) stream. 2.1 The 2 Wire Impedance. For the AG1460, the input impedance, Zin, of each SLIC is set to 600. For countries where the line impedance is 600 e.g. North America, no external adjustment is required. For countries where an alternative line impedance is used the Codec filter characteristics can be programmed to give the required matching. 1.3 Loop Off and Power Down The loop current can be removed from the line by switching the LO input to a logic 1. This can be used as a power denial to the line or to present a very high impedance to the line. Typically used when carrying out maintenance on the line, or to suspend service during a line fault, etc. Country USA Germany Spain South Africa Europe CTR21 Termination Impedance 600R Balance Impedance 600R ZT 150K 150K ZB 150K 100pF 220R 820R 220R 820R 56K 200K 150K 150K 100pF 120nF 120nF 470pF 68K 180K 270R 750R 270R 750R 150K 150K 150nF 300R 1000R 150nF 370R 620R 620pF 75K 240K TBD 100pF TBD UK 220nF 310nF 910pF TBD TBD Table 1: Impedance Programming for AG1460P (c) Silver Telecom 2004 V1.4 May 2004 Data Sheet The Codec manufacturer can provide information on how Codec programming is done. Programmable Codecs require information about the transfer characteristics of the SLIC with which they are working, which is contained in a .CIR netlist. A .CIR netlist can be obtained by contacting either Silver Telecom or your local representative, to allow the Codec programming coefficients to be generated. If a simple (non-programmable) Codec is being used, the AG1460P provides programming of Zin through hardware. The input impedance, Zin, of the SLIC can be set to the required value by connecting the appropriate impedance across pins ZT1 and ZT2. The scaling factor is 250 so a resistor of value 150kohms will give an impedance of 600R tip to ring. In this way the requirements of many countries may be met with one common linecard layout. Different values of the ZT components are only parts requiring change. Typical combinations are shown in table 1. AG1460 QUAD 5V RINGING SLIC If F/R is held at logic 1 (forward) the d.c. voltage at Tip is positive with respect to Ring. If F/R is taken to logic 0 the voltage polarity is reversed. The F/R pin should not be left floating, and if not used should be tied high. 2.5 On Hook Transmission. The AG1460 is capable of on-hook transmission. This means analog signals can be transmitted from Vin through Tip and Ring and onto the line even when no loop current is flowing. This can be used when sending Caller Line Identification (CLI) information or for other "no ring" calls. The AG1460 will provide on hook transmission with a high impedance on Tip/Ring or where specific loads are demanded by Network Operators. 3.0 Switch Hook Detect Level When the subscriber goes "off-hook" loop current will begin to flow. If this current is above the detection threshold (10mA) the switch hook output, SHK, will switch to logic 1. It is recommended that software or hardware de-bouncing of the switch hook signal is used. This is to avoid short pulses due to contact bounce, which can cause a false switch hook output, triggering the incorrect system response. During loop disconnect dialling; SHK will pulse between logic 1 and logic 0 to indicate the digits being dialled. Again it is recommended that software debouncing is used to avoid false detection of digits. 2.2 Network Balance Impedance. The network balance impedance, Zb, of each SLIC is set to 600 for the standard AG1460. For countries where the network balance impedance is 600 e.g. North America, no external adjustment is required. For countries where an alternative network balance impedance is used the Codec filter characteristics can be programmed to give the required matching. The .CIR netlist is again needed to allow the Codec programming coefficients to be generated. If a simple Codec is being used the AG1460P is available, providing programming of ZB through hardware. The network balance impedance, ZB, of the SLIC is set to the required value by connecting the appropriate impedance between pins VIN and ZB. Where the input and balance impedances are the same, a resistor value of 300k should be used with a 100pF capacitor in a "T" configuration as shown in Table 1. Where the impedances are different, then no simple relationship exists. Some typical examples are shown in Table 1. For countries which are not shown, please contact Silver Telecom. 4.0 Protection of the AG1460 SLIC 4.1 Thermal Protection Should any SLIC be operated incorrectly, for example by accidentally shorting Tip and Ring to each other or to ground, there is a danger the power dissipation could exceed the maximum rating. In this case a thermal cut-off will ensure the device gradually powers down safely by reducing the loop current. Once the problem has been corrected the loop current will return to its normal level. This feature means that the SLIC can be used even when a thermal overload has occurred. 2.3 Transmit and Receive Gain. The gain in both the transmit direction (Tip/Ring to VOUT) and the receive direction (VIN to Tip/Ring) is set to 0dB. Normally any gain adjustments required by the user can be made by programming the Codec. 4.2 Lightning and Power Cross Protection. It is usual for the AG1460 to be used in "on-premise" applications, such as SOHO, CTI and VoIP. In this case power cross and lightning protection is not required, however in most `off-premise' applications, a subscriber circuit will be required to withstand over voltage conditions which could be caused by lightning or overhead power cables striking the telephone cables. It is therefore normal in "off-premise" 2.4 Tip & Ring Polarity Reversal. The AG1460 can reverse the battery voltage polarity at Tip and Ring via the F/R pin. (c) Silver Telecom 2004 V1.4 May 2004 Data Sheet applications to provide primary and secondary protection circuits to prevent damage to the SLIC. The AG1460 has been designed to be able to use low cost protection components and a typical circuit is shown in Figure 4. This circuit is suitable for most "onpremise" applications. With some additional components, the AG1460 will meet UL60950 requirements: a series element should be added - a combination of a fuse (e.g. 350mA, Bussman C515 or Littelfuse 220003) and a surge resistor (25 typically). Alternatively a Teccor F1250T or F0500T fuse may be used without a surge resistor. For ITU-T K20 power cross protection, a PTC thermistor (eg. type JH330L) of 30R is suitable. The lightning protection is provided by steering diodes connected to 0V and upgrading D1 to a Tranzorb device (Motorola or Semitron 1.5KE82A). For lightning and power cross protection, D1 should be upgraded further (5KP75). Just one Tranzorb is needed per linecard. AG1460 QUAD 5V RINGING SLIC It is the responsibility of the equipment designer to ensure that their system meets the requirements of the relevant regulatory bodies. Every effort is made to ensure that Silver Telecom products are compliant with the latest standards. 6.0 A Typical Application. The AG1460 has been designed to interface to any Codec, and is shown in a typical application in figure 4. For examples of the interface to various codecs, either visit the Silver Telecom web-site at www.silvertel.com, or contact Silver Telecom or their local representative. The status outputs from the SLIC are passed to the micro-controller. These signals can then be processed as necessary by the system software. Control over the ringing and reversals functions is achieved via the RM and F/R pins. The audio signals which are on the 4 wire side of the connection are coupled by 100nF capacitors to avoid d.c. level problems between the two devices. The AG1460 provides for a 2 wire impedance and a network balance impedance of 600. For other impedances a DSP codec can be used which can be programmed using applications information available from the codec manufacturer. The necessary transfer function parameters for the AG1460 are available from Silver Telecom. +5V 5.0 Approvals. It can be seen from the Electrical Characteristics given on subsequent pages that the SLIC has been designed to meet the equipment standards of as many major public telephone authorities as possible. 100uF + 10 + 100nF VCLAMP D1 D2 TIP +5VA GNDA 220uF +5VPWR VIN VOUT 100nF RING 100nF AG1460 TIP Analog path to/from codec D5 RING D3 D4 PGND CAP GNDPWR F/R RM LO PD SHK Control signals to/from codec or micro-controller 220nF AG1460 is fixed 600R impedance.

If a simple Codec, without programmable filtering characteristics, is to be used, then the AG1460P can provide user hardware programmable line and network balance impedances. Contact Silver Telecom for other applications circuits. 7.0 Layout Considerations. Figure 5 gives an example of the tracking needed for the AG1460. Tracks to the +5VPWR and GNDPWR should be made as thick as possible. Also to maximise the performance of the device signal tracks should be kept as short as possible. Finally, as is common in all designs, decoupling capacitors should be placed adjacent to the supply and ground pins.
