(www.quicknet.net) -Version 0.3.4 December 18, 1999 - -1.0 Introduction - -This document describes the first GPL release version of the Linux -driver for the Quicknet Internet PhoneJACK and Internet LineJACK -cards. More information about these cards is available at -www.quicknet.net. The driver version discussed in this document is -0.3.4. - -These cards offer nice telco style interfaces to use your standard -telephone/key system/PBX as the user interface for VoIP applications. -The Internet LineJACK also offers PSTN connectivity for a single line -Internet to PSTN gateway. Of course, you can add more than one card -to a system to obtain multi-line functionality. At this time, the -driver supports the POTS port on both the Internet PhoneJACK and the -Internet LineJACK, but the PSTN port on the latter card is not yet -supported. - -This document, and the drivers for the cards, are intended for a -limited audience that includes technically capable programmers who -would like to experiment with Quicknet cards. The drivers are -considered in ALPHA status and are not yet considered stable enough -for general, widespread use in an unlimited audience. - -That's worth saying again: - -THE LINUX DRIVERS FOR QUICKNET CARDS ARE PRESENTLY IN A ALPHA STATE -AND SHOULD NOT BE CONSIDERED AS READY FOR NORMAL WIDESPREAD USE. - -They are released early in the spirit of Internet development and to -make this technology available to innovators who would benefit from -early exposure. - -When we promote the device driver to "beta" level it will be -considered ready for non-programmer, non-technical users. Until then, -please be aware that these drivers may not be stable and may affect -the performance of your system. - - -1.1 Latest Additions/Improvements - -The 0.3.4 version of the driver is the first GPL release. Several -features had to be removed from the prior binary only module, mostly -for reasons of Intellectual Property rights. We can't release -information that is not ours - so certain aspects of the driver had to -be removed to protect the rights of others. - -Specifically, very old Internet PhoneJACK cards have non-standard -G.723.1 codecs (due to the early nature of the DSPs in those days). -The auto-conversion code to bring those cards into compliance with -today's standards is available as a binary only module to those people -needing it. If you bought your card after 1997 or so, you are OK - -it's only the very old cards that are affected. - -Also, the code to download G.728/G.729/G.729a codecs to the DSP is -available as a binary only module as well. This IP is not ours to -release. - -Hooks are built into the GPL driver to allow it to work with other -companion modules that are completely separate from this module. - -1.2 Copyright, Trademarks, Disclaimer, & Credits - -Copyright - -Copyright (c) 1999 Quicknet Technologies, Inc.

These are ISA or PCI bus devices that use Plug-n-Play for -configuration, and use no IRQs. The driver will support up to 16 -cards in any one system, of any mix between the two types. - -Note that you will need two cards to do any useful testing alone, since -you will need a card on both ends of the connection. Of course, if -you are doing collaborative work, perhaps your friends or coworkers -have cards too. If not, we'll gladly sell them some! - - -2.2 ISAPNP - -Since the Quicknet cards are Plug-n-Play devices, you will need the -isapnp tools package to configure the cards, or you can use the isapnp -module to autoconfigure them. The former package probably came with -your Linux distribution. Documentation on this package is available -online at: - -http://mailer.wiwi.uni-marburg.de/linux/LDP/HOWTO/Plug-and-Play-HOWTO.html - -The isapnp autoconfiguration is available on the Quicknet website at: - - http://www.quicknet.net/develop.htm - -though it may be in the kernel by the time you read this. - - -3.0 Card Configuration - -If you did not get your drivers as part of the linux kernel, do the -following to install them: - - a. untar the distribution file. We use the following command: - tar -xvzf ixj-0.x.x.tgz - -This creates a subdirectory holding all the necessary files. Go to that -subdirectory. - - b. run the "ixj_dev_create" script to remove any stray device -files left in the /dev directory, and to create the new officially -designated device files. Note that the old devices were called -/dev/ixj, and the new method uses /dev/phone. - - c. type "make;make install" - this will compile and install the -module. - - d. type "depmod -av" to rebuild all your kernel version dependencies. - - e. if you are using the isapnp module to configure the cards - automatically, then skip to step f. Otherwise, ensure that you - have run the isapnp configuration utility to properly configure - the cards. - - e1. The Internet PhoneJACK has one configuration register that - requires 16 IO ports. The Internet LineJACK card has two - configuration registers and isapnp reports that IO 0 - requires 16 IO ports and IO 1 requires 8. The Quicknet - driver assumes that these registers are configured to be - contiguous, i.e. if IO 0 is set to 0x340 then IO 1 should - be set to 0x350. - - Make sure that none of the cards overlap if you have - multiple cards in the system. - - If you are new to the isapnp tools, you can jumpstart - yourself by doing the following: - - e2. go to the /etc directory and run pnpdump to get a blank - isapnp.conf file. - - pnpdump > /etc/isapnp.conf - - e3. edit the /etc/isapnp.conf file to set the IO warnings and - the register IO addresses. The IO warnings means that you - should find the line in the file that looks like this: - - (CONFLICT (IO FATAL)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) # or WARNING - - and you should edit the line to look like this: - - (CONFLICT (IO WARNING)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) # - or WARNING - - The next step is to set the IO port addresses. The issue - here is that isapnp does not identify all of the ports out - there. Specifically any device that does not have a driver - or module loaded by Linux will not be registered. This - includes older sound cards and network cards. We have - found that the IO port 0x300 is often used even though - isapnp claims that no-one is using those ports. We - recommend that for a single card installation that port - 0x340 (and 0x350) be used. The IO port line should change - from this: - - (IO 0 (SIZE 16) (BASE 0x0300) (CHECK)) - - to this: - - (IO 0 (SIZE 16) (BASE 0x0340) ) - - e4. if you have multiple Quicknet cards, make sure that you do - not have any overlaps. Be especially careful if you are - mixing Internet PhoneJACK and Internet LineJACK cards in - the same system. In these cases we recommend moving the - IO port addresses to the 0x400 block. Please note that on - a few machines the 0x400 series are used. Feel free to - experiment with other addresses. Our cards have been - proven to work using IO addresses of up to 0xFF0. - - e5. the last step is to uncomment the activation line so the - drivers will be associated with the port. This means the - line (immediately below) the IO line should go from this: - - # (ACT Y) - - to this: - - (ACT Y) - - Once you have finished editing the isapnp.conf file you - must submit it into the pnp driverconfigure the cards. - This is done using the following command: - - isapnp isapnp.conf - - If this works you should see a line that identifies the - Quicknet device, the IO port(s) chosen, and a message - "Enabled OK". - - f. if you are loading the module by hand, use insmod. An example -of this would look like this: - - insmod phonedev - insmod ixj dspio=0x320,0x310 xio=0,0x330 - -Then verify the module loaded by running lsmod. If you are not using a -module that matches your kernel version, you may need to "force" the -load using the -f option in the insmod command. - - insmod phonedev - insmod -f ixj dspio=0x320,0x310 xio=0,0x330 - - -If you are using isapnp to autoconfigure your card, then you do NOT -need any of the above, though you need to use depmod to load the -driver, like this: - - depmod ixj - -which will result in the needed drivers getting loaded automatically. - - g. if you are planning on having the kernel automatically request -the module for you, then you need to edit /etc/conf.modules and add the -following lines: - - options ixj dspio=0x340 xio=0x330 ixjdebug=0 - -If you do this, then when you execute an application that uses the -module the kernel will request that it is loaded. - - h. if you want non-root users to be able to read and write to the -ixj devices (this is a good idea!) you should do the following: - - - decide upon a group name to use and create that group if - needed. Add the user names to that group that you wish to - have access to the device. For example, we typically will - create a group named "ixj" in /etc/group and add all users - to that group that we want to run software that can use the - ixjX devices. - - - change the permissions on the device files, like this: - - chgrp ixj /dev/ixj* - chmod 660 /dev/ixj* - -Once this is done, then non-root users should be able to use the -devices. If you have enabled autoloading of modules, then the user -should be able to open the device and have the module loaded -automatically for them. - - -4.0 Driver Installation problems. - -We have tested these drivers on the 2.2.9, 2.2.10, 2.2.12, and 2.2.13 kernels -and in all cases have eventually been able to get the drivers to load and -run. We have found four types of problems that prevent this from happening. -The problems and solutions are: - - a. A step was missed in the installation. Go back and use section 3 -as a checklist. Many people miss running the ixj_dev_create script and thus -never load the device names into the filesystem. - - b. The kernel is inconsistently linked. We have found this problem in -the Out Of the Box installation of several distributions. The symptoms -are that neither driver will load, and that the unknown symbols include "jiffy" -and "kmalloc". The solution is to recompile both the kernel and the -modules. The command string for the final compile looks like this: - - In the kernel directory: - 1. cp .config /tmp - 2. make mrproper - 3. cp /tmp/.config . - 4. make clean;make bzImage;make modules;make modules_install - -This rebuilds both the kernel and all the modules and makes sure they all -have the same linkages. This generally solves the problem once the new -kernel is installed and the system rebooted. - - c. The kernel has been patched, then unpatched. This happens when -someone decides to use an earlier kernel after they load a later kernel. -The symptoms are proceeding through all three above steps and still not -being able to load the driver. What has happened is that the generated -header files are out of sync with the kernel itself. The solution is -to recompile (again) using "make mrproper". This will remove and then -regenerate all the necessary header files. Once this is done, then you -need to install and reboot the kernel. We have not seen any problem -loading one of our drivers after this treatment. - -5.0 Known Limitations - -We cannot currently play "dial-tone" and listen for DTMF digits at the -same time using the ISA PhoneJACK. This is a bug in the 8020 DSP chip -used on that product. All other Quicknet products function normally -in this regard. We have a work-around, but it's not done yet. Until -then, if you want dial-tone, you can always play a recorded dial-tone -sound into the audio until you have gathered the DTMF digits. - - - - - - - - - - - - - - - - -
