1.1 Presentation

The Loop Start / Ground Start (LS/GS) board is also called Non Direct Dialing In (NDDI2-2)

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 NDDI2-2 board can connect up to eight 2-wire analog lines. Lines 1 to 4 are processed on

the mother board and lines 5 to 8 are processed on the QATI-2 daughter board.

The NDDI2-2 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 NDDI2-2(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 NDDI2-2(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 NDDI2-2 board.

For more information on the NDDI2-2 board configuration, see NDDI2-2(LS/GS) - Hardware

configuration .

For more information on the NDDI2-2 board connection, see NDDI2-2(LS/GS) - External

connections .

1.3 Functional blocks

The NDDI2-2 board is made up of the following functional blocks:

- Quad Low voltage Subscriber Line Audio - processing Circuit (QLSLAC),

- Analog interfaces,

- Digital Signal Processing (DSP) module,

- Common part,

- Power supply.

The following figure shows how the functional blocks of the NDDI2-2 board are organized.

1-3

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 coders-decoders

(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 (Time-Slot 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.).

1.3.2 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 line-card.

- 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 hang-up:

The interface allows the AC signalling received during the hang-up phase to be transmitted

from the line to the QLSLAC (to be detected by the DSP). This signaling can be ringing,

dual tone (DT-AS), DTMF, V23 or Bell202 type for line call identification messages (CLIP

function).

1.3.3 DSP module

The Digital Signal Processing (DSP) module has the following functions:

      ! "  #$!%$!  &!'()'*

- 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 NDDI2-2 interfaces:

There are two types of tone:

• Dial tone,

• Busy tone.

- Ringing detection:

Eight ringing detection channels are necessary on the NDDI2-2 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 NDDI2-2 board. The TAS can be :

• Dual Tone Alert Signalling (DT-AS),

• Ringing Pulse Alert Signalling (RP-AS).

- Frequency Shift Keying (FSK) demodulation:

Eight FSK demodulation channels are necessary on the NDDI2-2 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 Multi-Frequency (DTMF) detection:

In some countries, the messages can be transmitted using the 16 DTMF codes.

1.3.4 Common part

The common part is the interface between the NDDI2-2 board and the other ACT boards.

The Revision Code Number (RCN) register of the QLSLAC recognizes the NDDI2-2 board.

The MIC 0 link rated at 2.048 MHz transmits voice for 8 NDDI2-2 lines.

For more information on the common part, see Common Part - Common part.

1.3.5 Power supply

From -48V power supply, the CM8 converter supplies the NDDI2-2 board with +5V, -5V and

+12V.

3.3V regulators supply the QLSLAC and the DSP module.
