==Why do noises appear while using the FXM-8A/PCI or FXM-16A/PCIe board?===
It may be due to the incomplete downloading of the firmware after Zaptel/Dahdi installation. Please make sure the network is well connected when you execute the command ./Setup install.

===How to determine the board arrangement when there are more than one AST board?===
If zaptel is configured automatically, you may check /etc/zaptel.conf or /etc/dahdi/system.conf to see the board arrangement.
If zaptel is configured manually, you may execute the command #cat /var/log/messages | grep "Launching card" to check the board arrangement.
If the board arrangement is determined by their serial number, pay attention to the time when you execute the command.

===How to install the SynAST driver in a dahdi version for which driver and tools are published separately?===
Please download the driver and tools of dahdi separately. <br />

1.By Script
<pre>
#cd /opt # enter the directory to source codes
#tar –zxvf SynAST-2.0.1.0.tar.gz # decompress the SynAST driver
#cd SynAST-2.0.1.0 # enter the directory to the SynAST driver
#cd dahdi # enter the directory to the ‘synway ast for dahdi’ driver
#./Setup install # install the driver
Would you like to install SynAST AST package now? y # enter ‘y’ to install
Please enter working dahdi directory [q](exit install) : /opt/dahdi_driver
# enter the directory to dahdi_driver source codes
Please enter dahdi_tools source directory [q](exit install):
# enter the directory to dahdi_tools source codes
SELECT TEJ MODE [t, e, j] :e # select the tej mode, or the driver will be installed in e1 mode
SELECT TEJXAPCI [75, 120]ohm # set the impedance of the TEJ pci board, 75 for coaxial cables, 120 for twisted-pair cables
SELECT TEJ201E [75, 120]ohm # set the impedance of the tej201e board, 75 for coaxial cables, 120 for twisted-pair cables
</pre>
2.Manually
<pre>
#cd /opt # enter the directory to the package of SynAST source codes
#tar –zxvf SynAST-2.0.1.0.tar.gz # decompress the source codes
#cp –rf /opt/SynAST-2.0.1.0/dahdi/srcs/fxm/fxm8apci /opt/dahdi_driver/drivers/dahdi
# copy the fxm8apci driver to the dahdi_driver directory.
#cd /opt/dahdi/linux/drivers/dahdi/fxm8apci
# enter the directory to SynAST source codes in dahdi
#make # compile the driver
#insmod fxm8apci.ko # load the driver

#cd /opt/dahdi_tools # enter the directory to dahdi tools
#./configure
#make # compile dahdi_tools
#make install # install dahdi_tools
</pre>

===How to determine the use of Zaptel or Dahdi for Asterisk?===
For Asterisk-1.4.21 and versions below, use Zaptel; for Asterisk-1.4.22 and versions above, use Dahdi.

===How to solve the problem that the system fails to detect the hangup at remote end as the volume of the recorded busy tone is quite low? ===
Modify the file main/dsp.c under the Asterisk directory, changing the previous content ‘#define DEFAULT_THRESHOLD 512’ to ‘#define DEFAULT_THRESHOLD 448’. The value can be reduced again if the problem is not solved yet.

===How to solve the problem that the zaptel driver fails to be installed in the system of Ubuntu 8.10, kernel 2.6.27-7-server?===
Use the dahdi driver.

===How to solve the problem that the configuration files zaptel.conf and zapata.conf cannot be found under dahdi?===
/etc/dahdi/system.conf under dahdi corresponds to /etc/zaptel.conf under zaptel. The configuration files system.conf and zaptel.conf, although differ in name, are the same in content.
/etc/asterisk/chan_dahdi.conf under dahdi corresponds to /etc/asterisk/zapata.conf under zaptel. The configuration files chan_dahdi.conf and zapata.conf, although differ in name, are the same in content.

===How to solve the failure of FXM boards to receive the calling party number? ===
If you are using a version of zaptel, please uninstall it first. Then install a dahdi version and operate as follows (take the FXM-8A/PCI board for example).
Execute the command ‘echo 32 > /sys/module/fxm8apci/parameters/ringdebounce’. Then test if the board can well receive the calling party number. If the reception still fails, change 32 in this command to 16 or 8 and retest.
Note: If the file /sys/module/fxm8apci/parameters/ringdebounce does not exist, modify the command to ‘echo 32 >/sys/module/fxm8apci/ringdebounce’.

===How to use the function of FXM series boards to adjust recording and playback volumes?===
This volume adjustment function is valid to all channels on the same kind of boards. The value range of the parameter x is 1~255 which represents the DB value of 20log(x/10).
To adjust the recording volume for FXM-8A-PCI, execute the command:
echo x > /sys/module/fxm8apci/parameters/recvolume;
To adjust the playback volume for FXM-8A-PCI, execute the command:
echo x > /sys/module/fxm8apci/parameters/playvolume;
To adjust the recording volume for FXM-16A-PCIe, execute the command:
echo x > /sys/module/fxm16apcie/parameters/recvolume;
To adjust the playback volume for FXM-16A-PCIe, execute the command:
echo x > /sys/module/fxm16apcie/parameters/playvolume
To adjust the recording volume for FXM-32, execute the command:
echo x > /sys/module/fxm32/parameters/recvolume
To adjust the playback volume for FXM-32, execute the command:
echo x > /sys/module/fxm32/parameters/playvolume
