Chapter 1 Overview

FXM32 is designed with a smart appearance and a flexible structure. The voice quality it provides is rather splendid. The echo canceller which we developed out independently to cancel echoes in hardware supports 128ms for time delay estimation. With the extendable daughterboards and the selectable modules, you can customize systems to what you want. The 2U height and the half-length design it has minimize the space to install in a chassis so that most common main frames you find in daily life are big enough to hold it. In a word, this product is really cost effective.

Figure 1-1 below shows the overall structure of FXM32.

Figure 1-1 Overall Structure of FXM32

Note: When installing motherboards and daughterboards, there will be no difference to put whichever one in front. They can be inserted into any slot on the backboard. See Figure 2-1.

1.1 Features

z Echo Cancellation

1) Compliant with G.168-2002.

2) The basic motherboard supports 256 point (32ms) for time delay estimation on each

Synway FXM32 Analog Voice Board Hardware Manual (Version 1.0) Page 1

Page 7

Synway Information Engineering Co., Ltd

channel while the enhanced motherboard supports 1024 point (128ms).

3) Uses the DSPs on the motherboard to process echoes, not wasting any host resources.

4) Not only cancels out the effect of voice playback on DTMF and busy tones detection, but also avoids self-excited oscillation and howling, minimizes the possibility of registering wrong DTMF and busy tones in a conference call, especially suitable for VoIP application environments.

z DMA

Uses the DMA technique for data reading and writing, greatly minimizing the cost of host CPU.

z Structure

1) Assembles piecemeal just like piling up building blocks. A motherboard offers 4 channels and you may use the backboard to extend with up to 7 daughterboards. Then 32 channels are available in total. Although these daughterboards take some space, they can work without the need of PCI/PCIe slots.

2) Several kinds of modules are optional for you to install with the mother/daughter boards to achieve different purposes. Actually, we provide FXS, FXO and FXC (a compound body of FXS and FXO). FXC has the capability to ensure safe communication even when the PC is powered off, which eliminates the damage caused by sudden power cuts.

3) The 2U height and the half-length de sign (Height: 55mm, Length: 120mm) minimize the space it needs for installation, allowing a great many choices of mainboards and main frames.

4) You are allowed to fix the module by bolt and the backboard by ouch onto the mother/daughter board to prevent them from loosening or disengaging during transportation or in removal.

z Compatibility in Software and Hardware

1) Compatible with all commercial and home mainboards.

2) Includes PCI 2.2 bus with burst data transmission rate up to 132 MB/s; PNP (plug and play) feature eliminates the need for jumper leads; general PCI design supports 3.3V/5V PCI slot and PCI-X slot.

Includes PCI Express 1.0a bus with the single-way transmission rate up to 2.5Gb; supports PCI Express X1, X2, X4, X8, X16 slots.

3) Supports Unix, Linux and Solaris.

4) This board driver is compatible with Zaptel. So it supports a lot of open source PBX systems, like Asterisk, Trixbox, Yate, CallWeaver, FreeSwitch, etc.

z Interface

The on-board RJ11 jack can connect directly to telepho ne lines, making connection easy and

malfunctions rare.

z Power

The power for motherboard is supplied by PCI/PCIe slot, while that for backboard and daughterboard is supplied by host-computer power.

z Indicator

Rear projection indicators. We make use of the gaps between RJ11 jacks and the light-admitting quality of the jack to hide the indicators behind the RJ11 jacks. Such design not only ensures the neatness of the board, but also allows you to get the module type and errors in running without opening the main frame.

Figure 2-7 Modules and RJ11 Jacks

Note:

1) What each RJ11 jack corresponds to is the module position but not the module type. For example, as shown in Figure 2-7 above, Port 1 and Port 2 are connected to Module 1, no matter Module 1 is FXO, FXS or FXC. Likewise, Port 3 and Port 4 correspond to Module

2) Interfaces and modules for daughterboards are the same as those on the motherboard.

3) When an FXM32 board is running, the indicators at the RJ11 jacks corresponding to trunk channels stay red, and those at the RJ11 jacks corresponding to station channels stay green. The indicators being unused will not light up. Take the board in Figure 2-7 for example, the color of indicators at each interface are as shown in Figure 2-8 below.

2.3 Channel Number Identification

An FXM32 set provides up to 32 channels, each of which has a fixed number. The channel number is only decided by ‘the slot position on the backboard’ and ‘the port

position on the mother/daughter board’. See Figure 2-10 below. The slots on the backboard are numbered 1~8 from left to right. Then see the following Figure 2-11. The on-board channels are numbered 1~4 from top to bottom.

When the mother/daughter board is fitted to the backboard, the channels on the board which is

inserted to Slot 1 on the backboard are numbered CH1~CH4, and those on the board which is inserted to Slot 2 on the backboard are numbered CH5~CH8. Then in turn, the channels on the board which is inserted to Slot 8 on the backboard are numbered CH29~CH32.

Note: Each position has a fixed channel number. It doesn’t matter where the mother/daughter board is on the backboard or if there is a board inserted on a slot, just as shown in Figure 2-12 below.

Fix the screws on the L-bracket and then go to the next step.

Note: Skip the following Step 4 and Step 5 if you do not use any daughterboard. Step 4: Fit the daughterboard onto the chassis.

Likewise, fix the screws on the L-bracket and then go to the next step.

Note: Daughterboards need not be inserted into PCI/PCIe slots. And it has no

difference to put whichever one of them in front. Step 5: Meet the HD power cord to the backboard to connect motherboards with

daughterboards.

Figure 2-14 below shows how to insert the power cord of the chassis to the backboard.

HD Power Plug

Figure 2-14 Fit HD Power Plug to Backboard

Note:

1) Skip this step if you do not use any daughterboard.

2) You may choose a suit able backboard according to ho w many daughterboards you need. See Table 2-1 to find the backboard models we supply.

Step 6: Set up an application environment

Connect phone lines with the port to an FXO module and the telephone with the port to an FXS module, to establish an application environment.

Step 7: Connect the clock synchronization line

Note: Skip this step if there is no need to get clock synchronization for multiple bo ards.

The clock synchronization line is used to connect more than one FXM32 motherboards or connect FXM32 boards with other kinds of boards (e.g. digital trunk boards) so that these boards can use a same clock to reduce the errors in faxing and to ensure the accuracy of data transmission between different boards. (Note: The synchronization of FXM32 motherboards and daughterboards is achieved by backboards instead of the clock synchronization line.)

See Figure 2-15 below.

Figure 2-15 Clock Synchronization Line

See Figure 2-2 for the clock synchronization line interface on the motherboard.

Step 8: Boot your computer and install the driver

Regarding driver installation, refer to the file ‘SynAST UserManual.doc’ for details.
