Building drivers:
""""""""""""""""
-Unlike earlier versions, the Astribank driver (xpp) will now build
-automatically. To build the drivers follow the usual Zaptel
-documentation. E.g: run:
-
- make
-
-in the top-level directory.
-
-Next you will need to build the user-space tools needed for loading the
-firmware and initialization files for the Astribank:
-
- make -C xpp/utils
-
-INSTALLATION:
+From the toplevel zaptel directory run a command similar to (I used line
+continuation to prevent line wrapping):

+ KVERS=2.6.12-1-386 \
+ XPPMOD=xpp/ \
+ EC_TYPE=CAN_KB1
+
+ - The KSRC= points to a configured kernel source tree.
+ - The KVERS= should match the relevant tree version.
+ - The XPPMOD= instructs the Zaptel Makefile to descend into the xpp/
+ subdirectory. The slash (/) in the end is mandatory.
+ - The EC_TYPE= select the echo canceler.
+
+Building firmware utilities:
+"""""""""""""""""""""""""""
+Then you should compile the firmware loading utilities. Simply go
+to the zaptel/xpp/utils and run make.
+
+Those who don't use prepackaged drivers should make sure they also

-DEVICE STARTUP:
-""""""""""""""
-
-Terminology:
-"""""""""""
-Some technical terms that are used throughout the document and in the
-driver / zaptel . Only used in the technical parts.
-
-span:
-Zaptel breaks the channels it knows bout to logical units called
-"spans". A port in a E1/T1/ISDN card is usually a span. So is a complete
-analog card. You can see the list of spans as the list of files under
-/proc/zaptel or the list in zttool.
-
-XBUS:
-A funny way to call an Astribank device.
-
-XPD:
-This is basically a subunit of the Astribank. It will be registered to
-Zaptel as a single span. This will basically be 8 analog channels.
-
-
-Loading Firmware:
-""""""""""""""""
-Normally this is done using the script xpp_fxloader.If it works fine,
-you don't need to bother reading this section.
-Once the firmware is loaded the USB ID of the Astribank changes to e4e4
-1132, and the driver can pick it up. You'll also see the top led lit.
-
-First and foremost: the simplest and most useful tool to debug problems
-here is lsusb. The output of lsusb should show exactly if the device is
-connected and if its firmware is loaded.
-
-The firmware files are named *.hex. The are in the Intel hex format
-(read: plain text, but not readable) that is copied at install time from
-xpp/utils to /usr/share/zaptel .
-
+Loading Firmware Details:
+""""""""""""""""""""""""
The Astribank needs a firmware loaded into it. Without the firmware,
-the device will appear in lsusb with vendor ID e4e4 and product ID 1130.
-The firmware is loaded in two stages. In the first stage we load the
-"USB" firmware using the program fxload. After the first stage the USB
-ID is e4e4 1131. In the second stage we load the "FPGA" firmware.
-
-The first is done using the the program fxload. To load it manually, use
-the command:
-
- fxload -t fx2 -D /proc/bus/usb/MMM/NNN -I /usr/share/zaptel/USB_1130.hex
-
-fxload is standard program that is typically part of the package 'fxload'
-or 'hotplug-utils' . /proc/bus/usb is the mount point of the USB
-file-system (usbfs). MMM is the first number (bus number) and NNN is the
-second number (device number) you see for the device in lsusb, with full
-3 digits. If the load is successful, the device disconnects and
-reconnects with USB product ID 1131 (and a new device number).
-
-The second-stage loader is done using the program fpga_load, which is
-built in the directory xpp/utils and installed to /usr/sbin/fpga_load .
-Its syntax is based on fxload. To load with it manually, use:
-
- fpga_load -D /proc/bus/usb/MMM/NNN -I /usr/share/zaptel/FPGA_FXS.hex
-
-Note that as the device has reconnected, it now has a new device
-number. So you need to re-check the value of NNN with lsusb. Typically
-this will be the old value + 1.
-
-
-Firmware Loading with UDEV:
-""""""""""""""""""""""""""
-Firmware loading with udev should work but is not installed
-automatically, yet. See the comments in the beginning of the script
-/etc/hotplug/usb/xpp_fxloader .
-
-Loading The Modules:
-"""""""""""""""""""
-Here is what should happen:
-In short: you should plug it or have it plugged at boot time, and all
-the modules should load. You will see xpp_usb , xpd_fxs and possibly
-xpd_fxo in the modules list (the output of lsmod).
-
-After the module xpp is loaded, you'll also be able to see the directory
-/proc/xpp . For any unit discovered there you will see a directory
-/prc/xpp/XBUS-n (where n is a number: typically 0). Once subunit have
-been discovered you'll see subdirectories: /proc/xpp/XBUS-n/XPD-m (where
-m may be another number: 0, 1 ,etc).
-
-Now to the ugly details:
-
-The driver of the Astribank is composed of several modules: xpp is the
-basic one, that contains the functionality to connect to Zaptel and other
-common functions. xpd_fxs is the module for controlling FXS spans.
-xpd_fxo is the module for controlling FXO spans. xpd_usb is the module
-that holds the functionality needed to connect to the USB bus.
-
-All modules depend on xpp, and modprobing them will install xpp as well.
-However the xpd_* modules are only installed on-demand: no need to
-install xpd_fxo if you only have FXS Astribank.
-
-You either plug in the Astribank , or start the hotplug/udev system
-while an Astribank is connected, after the firmware is loaded. The
-Vendor-ID/Product-ID of the device is e4e4/1132 . The handler for that
-combination is listed as the kernel module xpp_usb . Thus the system
-runs 'modprobe xpp_usb' if that module is not already loaded.
-
-The module xpp_usb depends on the modules zaptel and xpp . Both of which
-are loaded before xpp_usb is loaded. As usual, parameters and rules form
-/etc/modprobe.conf and/or /etc/modprobe.d/* will apply to the module, as
-modprobe is used.
-
-The modules to handle the specific span types (xpd_fxs, xpd_fxo) may or
-may not have been loaded yet at this stage (when the command 'modprobe
-xpp_usb' returns).
-
-At this point the xpp driver asks the box what units it has. According to
-the answers it gets, it will figure what xpd_* modules it will need, and
-modprobe for them. At some earlier version of the driver this has
-required some special modprobe.conf setup, but this is no longer
-the case.
-
-
-Device Initializations Scripts:
-""""""""""""""""""""""""""""""
-The chips in the device need to be initialized. This involves sending a
-bunch of values to certain registers in those chips. We decided that
-hardwiring those values in the driver itself would not be a good idea.
-
-before registering a XPD as a span in Zaptel, we run an initialization
-script: /usr/share/zaptel/initialize_registers . If this fails (e.g:
-because the script is not there, or is not executable), you will get an
-error message in the logs [FIXME: quote error message] that the
-invocation has failed. The XPD will then be removed (you won't see that
-a directory for that XPD under the relevant /proc/xpp/XBUS-* directory)
-and not be registered with Zaptel.
-
-Registering With Zaptel:
-"""""""""""""""""""""""
-Now we finally got to the "lights party" part: the lights in a subunit
-(XPD) get lit before it registers with Zaptel and are turned off after
-that.
-
-You may choose not to register the XPDs to Zaptel automatically, to
-allow finer control of the process. This is done using the module
-parameter zap_autoreg. Set in the modprobe configuration file (e.g:
-/etc/modprobe.conf ) the line:
-
- options xpp zap_autoreg=0
-
-to disable automatic registration at startup. You will then need to
-register the spans manually.

+
+You should then get in lsusb the vendor ID e4e4 and device ID 2121
+(those IDs are temporary and likely to change in upcoming versions).
+Once there is such a device, the xpp_usb driver should load

+disconnect and reconnect the device than running 'modprobe xpp_usb'.
+
+
+The driver has been separated into several modules: xpp.ko, xpd_fxs.ko and
+xpp_usb.ko . Generally you only need to modprobe xpp_usb, and it should also
+be loaded by hotplug when you connect the Astribank. However in order for it
+to load xpd_fks.ko correctly

+Refer to the instructions for Zaptel. After our small patches were applies,
