7 1.1 Presentation The Loop Start / Ground Start (LS/GS) board is also called Non Direct Dialing In (NDDI22) board. It is an analog board which allows the Private Automatic Branch exchange (PABX) to be connected to most public networks. Furthermore, this board allows the PABX to be connected to a pager system according to the ESPA standard. The NDDI22 board can connect up to eight 2wire analog lines. Lines 1 to 4 are processed on the mother board and lines 5 to 8 are processed on the QATI2 daughter board. The NDDI22 board can handle the following optional daughter boards : Calling Line Identification Protocol Interface Adaptor (CLIPIA) board: This board allows the line impedance to be modified to identify the caller and to detect the metering pulses. For more information on the CLIPIA board, see NDDI22(LS/GS) CLIPIA Daugtherboard Operation. Tax Metering board: This board is used to detect 12/16 KHz metering pulses. For more information on the Tax Metering board, see NDDI22(LS/GS) Metering Detection Daughter Board. Ground Start board: This board is used to seize the line via the ground and to detect incoming calls via grounding a line wire. Note: The Ground Start board is only available in the US market. Each daughter board is dedicated to 4 network lines, i.e. 2 daughter boards are necessary to handle 8 lines of an NDDI22 board. For more information on the NDDI22 board configuration, see NDDI22(LS/GS) Hardware configuration. For more information on the NDDI22 board connection, see NDDI22(LS/GS) External connections. 1.2 Environment changebegin The following figure shows the front and back panel connections of the NDDI22 board.!

10 Chapter 1 #$! %$! &!'()' * A/D and D/A voice signal conversion is ensured by 2 QLSLAC circuits. Each Quad Low voltage Subscriber Line Audio processing Circuit (QLSLAC) contains 4 codersdecoders (CODECS) and supports 4 analog interfaces. One Time Division Multiplex (TDM) or TS allocation connects both QLSLAC to circuit C1. The QLSLAC acts as: an interface between : the Pulse Code Modulation (PCM) bus (TimeSlot Assigner (TSA)) and the processor, the SLIC OET/CET management and 4 Signal Processing Channels (SPC), the programmable software for transmission features (input impedance, reception and transmission gains, echo cancellation, µ or A laws coding, etc.). Analog interfaces Analog interfaces: control the signalling, transmit voice, receive messages to identify the caller (CLIP), if any. Interfaces are made up of the following parts: protection circuits which consist of: overvoltage protection circuits to avoid damage in case of any short circuit, EMI filtering circuits to reduce the RFI effects on the telephone linecard. impedance for ringing signal: A firmware command allows a low or high impedance to be connected. This command allows, with a specific equipment (country dedicated daughter board), either a ringing impedance or a spark quench circuit to be connected (loop protection circuit during dialing). loop circuits which can be: on line loop, a high dynamic impedance circuit with DC current limitation (compatible with TBR21), dialing loop (very low resistance). loop current detector. polarity detector: Still used for paging, its use depends on the country for NDDI operation. The polarity can be detected only if a DC current loop is present. interface for AC signalling at hangup: The interface allows the AC signalling received during the hangup phase to be transmitted from the line to the QLSLAC (to be detected by the DSP). This signaling can be ringing, dual tone (DTAS), DTMF, V23 or Bell202 type for line call identification messages (CLIP function). DSP module The Digital Signal Processing (DSP) module has the following functions: 14! " #$! %$! &!'()' *

11 #$! %$! &!'()' * Tone detection: Eight channels are available for tone detection. The different paces are validated by the firmware coupler, levels and frequencies are validated by the DSP software. External tone detection on the NDDI22 interfaces: There are two types of tone: Dial tone, Busy tone. Ringing detection: Eight ringing detection channels are necessary on the NDDI22 board. The different paces are validated by the firmware coupler, levels and frequencies are validated by the DSP software. The detector must handle frequencies ranging from 14.5 to 68 Hz. TAMIS Terminal equipment Alert Signaling (TAS) detection: Eight TAS detection channels are necessary on the NDDI22 board. The TAS can be : Dual Tone Alert Signalling (DTAS), Ringing Pulse Alert Signalling (RPAS). Frequency Shift Keying (FSK) demodulation: Eight FSK demodulation channels are necessary on the NDDI22 board (eight FSK carrier detections are provided). FSK has the following features: bit duration: 833 µs, 0 logical frequency: 2200 ± 22 Hz (Bellecore) or 2100 ± 16 Hz (ETSI), 1 logical frequency: 1200 ± 12 Hz (Bellecore) or 1300 ± 16 Hz (ETSI), Signal level reception: 12 to 32.5 dbm (Bellecore) or 11 to 35 dbm (ETSI). Dual Tone MultiFrequency (DTMF) detection: In some countries, the messages can be transmitted using the 16 DTMF codes. Common part The common part is the interface between the NDDI22 board and the other ACT boards. The Revision Code Number (RCN) register of the QLSLAC recognizes the NDDI22 board. The MIC 0 link rated at MHz transmits voice for 8 NDDI22 lines. For more information on the common part, see Common Part Common part Power supply From 48V power supply, the CM8 converter supplies the NDDI22 board with +5V, 5V and +12V. 3.3V regulators supply the QLSLAC and the DSP module.!

25 4.1 Overview The Call Line Identification Protocol Interface Adaptator (CLIPIA) daughter board allows the line impedance to be modified for: the CLIP function, the metering function. A daughter board handles 4 lines. You need 2 CLIPIA daughter boards for an NDDI22 (LS/GS) board. For more information on the CLIPIA board configuration, see NDDI22(LS/GS) CLIPIA Daughterboard Configuration. For more information on the CLIPIA board connection, see NDDI22(LS/GS) External connections. 4.2 CLIP function You need a line impedance of 600 Ohms (conversation excluded) to use the CLIP protocol. The CLIPIA board has, for each line, a relay controlled by the mother board allowing the 600Ohm line to be connected when it is not in conversation mode. 4.3 Metering function To manage accounting pulse reception on the line in some countries, you need a low impedance of 12 or 16 KHz (selected by a build). The CLIPIA board comprises a resonant circuit per line, a jumper allows a resonance at 12 or 16 KHz to be selected. ()!. / 0 $,)1! $! 2(!$)' * 41
