Abstract

This manual provides a Installation and Reference Manual for OpenSS7 STREAMS Channels.

Objective

The objective of this manual is to provide a guide for the STREAMS programmer when developing STREAMS modules, drivers and application programs for OpenSS7 STREAMS Channels.

This guide provides information to developers on the use of the STREAMS mechanism at user and kernel levels.

STREAMS was incorporated in UNIX System V Release 3 to augment the character input/output (I/O) mechanism and to support development of communication services.

STREAMS provides developers with integral functions, a set of utility routines, and facilities that expedite software design and implementation.

Intent

The intent of this manual is to act as an introductory guide to the STREAMS programmer. It is intended to be read alone and is not intended to replace or supplement the OpenSS7 STREAMS Channels manual pages. For a reference for writing code, the manual pages (see STREAMS(9)) provide a better reference to the programmer. Although this describes the features of the OpenSS7 STREAMS Channels package, OpenSS7 Corporation is under no obligation to provide any software, system or feature listed herein.

Audience

This manual is intended for a highly technical audience. The reader should already be familiar with Linux kernel programming, the Linux file system, character devices, driver input and output, interrupts, software interrupt handling, scheduling, process contexts, multiprocessor locks, etc.

The guide is intended for network and systems programmers, who use the STREAMS mechanism at user and kernel levels for Linux and UNIX system communication services.

Readers of the guide are expected to possess prior knowledge of the Linux and UNIX system, programming, networking, and data communication.

Quick Start Guide

OpenSS7 STREAMS Channels

Package strchan-0.9.2.3 was released under GPLv2 2007-06-24.

The OpenSS7 STREAMS Channels package provides STREAMS modules and drivers, libraries, programs, init scripts, and daemons that implement the OpenSS7 STREAMS isochronous channels for the purpose of implementing data transmission links, or for carrying voice or other media, such as channelization of T1 carrier facilities, or ATM AAL3. This package also includes pseudo-isochronous channels such as those provided by RTP.

Included are hardware device drivers and pseudo-device drivers that provide implementations of specific channels. A pseudo-device driver is planned to link into the Linux OSS (Open Sound System) and ALS (Advanced Linux Sound). Specific E1/T1 cards such as the V401P are supported by this package. Also included is an experimental driver that operates also as a Zaptel driver for the purpose of OpenSS7/Asterisk integration (but see also the NOTES file in the release).

This package also supports data channel protocols for data communication over isochronous channels such as HDLC and SS7 DAEDR/DAEDT/AERM/SUERM. Upper layer link protocols, such as LAPB, LAPF, LAPM and LLC are supported by separate packages. These modules are provided here because they work directly over an isochronous channel and are therefore designed to work with them. These data links provide support for the OpenSS7 STREAMS ISO/OSI as well as the OpenSS7 STREAMS ISDN Stacks and OpenSS7 STREAMS SS7 Stack packages.

This package builds and installs the following STREAMS kernel modules and drivers:

ch(4)

The ch(4) multiplexing pseudo-device driver is a fully functional channel device capable of channelized, fractional or full-span E1/T1/J1 statistically multiplexed channels. Streams opened on this device driver support delivery of the raw octet streams associated with the multiplexed channel.

mx(4)

The mx(4) multiplexing pseudo-device driver is a fully functional matrix switching device capable of switching, performing rate adaption, echo cancellation, digital padding, conferencing, tones, announcements, detection of tones, detection of speech, continuity tests, progress tones, A-law/mu-law conversion, decompression/compression, comb filtering, and other functions of a digital switching matrix.

mg(4)

The mg(4) multiplexing pseudo-device driver is a fully functional media gateway device capable of providing conversion between Circuit Switched Network connections (via the mx(4) driver) and Ephemeral RTP streams (via the rtp(4) module and udp(4) driver). This device also supports Media Gateway Control Protocol communications of several forms over tcp(4) and sctp(4).

pwe3(4)

The pwe3(4) module is a pushable STREAMS module that is pushed over a tcp(4) or sctp(4) Stream to provide pseudo-wire emulation end-to-end. This device appears as though it is a channel device.

zaptel(4)

The zaptel(4) multiplexing pseudo-device driver is a STREAMS driver that provides the historical zaptel(4) interface for asterisk and other open-PBX packages. mx(4) streams are linked under the driver and represent spans that can be managed by zaptel(4).

cd_hdlc(4)

The cd_hdlc(4) module is a pushable STREAMS module that provides the capabilities of the High-Level Data Link Control and can be pushed over a raw ch(4) channel to provide a Communications Device Interface (CDI) or Data Link Provider Interface (DLPI) suitable for use with ISO/OSI protocols, X.25, ISDN or Frame Relay.

cd_daed(4)

The cd_daed(4) module is a pushable STREAMS module that provides th capabilities of SS7 High-Level Data Link Control (Q.702) and can be pushed over a raw ch(4) channel to provide a Communications Device Interface (CDI) or Signalling Data Terminal Interface (SDTI) suitable for use with SS7 protocols.

The OpenSS7 STREAMS Channels package includes kernel modules, SVR 4.2 STREAMS drivers, modules, libraries, utilities, test programs, daemons, and development environment for the development and execution of OpenSS7 STREAMS Channels applications for the SVR 4.2 STREAMS environment.

This package is currently incomplete. It is being released as a reference point for the community. If you are interested in completion of this package, sponsor the OpenSS7 Project. To sponsor the project, contact info@openss7.com.

This distribution is only currently applicable to Linux 2.4 and 2.6 kernels and was targeted at ix86, x86_64, ppc and ppc64 architectures, but should build and install for other architectures as well.

If you are interested in different licensing terms, please contact the copyright holder, or OpenSS7 Corporation <sales@openss7.com>.

See README-alpha (if it exists) for alpha release information.

Prerequisites

The quickest and easiest way to ensure that all prerequisites are met is to download and install this package from within the OpenSS7 Master Package, openss7-0.9.2.F, instead of separately.

Prerequisites for the OpenSS7 STREAMS Channels package are as follows:

1. Linux distribution, somewhat Linux Standards Base compliant, with a 2.4 or 2.6 kernel and the appropriate tool chain for compiling out-of-tree kernel modules. Most recent Linux distributions are usable out of the box, but some development packages must be installed. For more information, see Compatibility.

   	− A fairly LSB compliant GNU/Linux distribution.2
   	− Linux 2.4 kernel (2.4.10 - 2.4.27), or
   	− Linux 2.6 kernel (2.6.3 - 2.6.21);
   	− glibc2 or better.
   	− GNU info (for info files).
   	− GNU groff (for man pages).3

(Note: If you acquired strchan a part of the OpenSS7 Master Package, then the dependencies listed below will already have been met by unpacking the master package.)

2. OpenSS7 Linux Fast-STREAMS, streams-0.9.2.3. ⁴
3. OpenSS7 STREAMS Compatibility Modules, strcompat-0.9.2.6.
4. OpenSS7 STREAMS XNS, strxns-0.9.2.6.

When configuring and building multiple OpenSS7 Project release packages, place all of the source packages (unpacked tarballs) at the same directory level and all build directories at the same directory level (e.g. all source packages under /usr/src).

When installing packages that install as kernel modules, it is necessary to have the correct kernel development package installed. For the following distributions, use the following commands:

     Ubuntu:  $> apt-get install linux-headers
     Debian:  $> apt-get install kernel-headers
     Fedora:  $> yum install kernel-devel

You also need the same version of gcc(1) compiler with which the kernel was built. If it is not the default, add `CC=kgcc' on the line after `./configure', for example:

     $> ../strchan-0.9.2.3/configure CC='gcc-3.4'

Installation

The following commands will download, configure, build, check, install, validate, uninstall and remove the package:

     $> wget http://www.openss7.org/tarballs/strchan-0.9.2.3.tar.bz2
     $> tar -xjvf strchan-0.9.2.3.tar.bz2
     $> mkdir build
     $> pushd build
     $> ../strchan-0.9.2.3/configure --enable-autotest
     $> make
     $> make check
     $> sudo make install
     $> sudo make installcheck
     $> sudo make uninstall
     $> popd
     $> sudo rm -rf build
     $> rm -rf strchan-0.9.2.3
     $> rm -f strchan-0.9.2.3.tar.bz2

If you have problems, try building with the logging targets instead. If the make of a logging target fails, an automatic problem report will be generated that can be mailed to The OpenSS7 Project.⁵ Installation steps using the logging targets proceed as follows:

     $> wget http://www.openss7.org/tarballs/strchan-0.9.2.3.tar.bz2
     $> tar -xjvf strchan-0.9.2.3.tar.bz2
     $> mkdir build
     $> pushd build
     $> ../strchan-0.9.2.3/configure --enable-autotest
     $> make compile.log
     $> make check.log
     $> sudo make install.log
     $> sudo make installcheck.log
     $> sudo make uninstall.log
     $> popd
     $> sudo rm -rf build
     $> rm -rf strchan-0.9.2.3
     $> rm -f strchan-0.9.2.3.tar.bz2

See README-make for additional specialized make targets.

For custom applications, see the INSTALL and INSTALL-strchan files or the see Installation, as listed below. If you encounter troubles, see Troubleshooting, before issuing a bug report.

Brief Installation Instructions

The OpenSS7 STREAMS Channels package is available from the downloads area of The OpenSS7 Project website using a command such as:

     $> wget http://www.openss7.org/tarballs/strchan-0.9.2.3.tar.bz2

Unpack the tarball using a command such as:

     $> tar -xjvf strchan-0.9.2.3.tar.bz2

The tarball will unpack into the relative subdirectory named after the package name: strchan-0.9.2.3.

The package builds using the GNU autoconf utilities and the configure script. To build the package, we recommend using a separate build directory as follows:

     $> mkdir build
     $> cd build
     $> ../strchan-0.9.2.3/configure

In general, the package configures and builds without adding any special options to the configure script. For general options to the configure script, see the GNU INSTALL file in the distribution:

     $> less ../strchan-0.9.2.3/INSTALL

For specific options to the configure script, see the INSTALL-strchan file in the distribution, or simply execute the configure script with the --help option like so:

     $> ../strchan-0.9.2.3/configure --help

After configuring the package, the package can be compiled simply by issuing the `make' command:

     $> make

Some specialized makefile targets exists, see the README-make file in the distribution or simply invoke the `help' target like so:

     $> make help | less

After successfully building the package, the package can be checked by invoking the `check' make target like so:

     $> make check

After successfully checking the package, the package can be installed by invoking the `install' make target (as root) like so:

     $> sudo make install

The test suites that ship with the package can be invoked after the package has been installed by invoking the `installcheck' target. This target can either be invoked as root, or as a normal user, like so:

     $> make installcheck

(Note: you must add the --enable-autotest flag to configure, above for the test suites to be invoked with `make installcheck'.)

The package can be cleanly removed by invoking the `uninstall' target (as root):

     $> sudo make uninstall

Then the build directory and tarball can be simply removed:

     $> cd ..
     $> rm -rf build
     $> rm -rf strchan-0.9.2.3
     $> rm -f strchan-0.9.2.3.tar.bz2

Detailed Installation Instructions

More detailed installation instructions can be found in the Installation, contained in the distribution in `text', `info', `html' and `pdf' formats:

     $> cd ../strchan-0.9.2.3
     $> less doc/manual/strchan.txt
     $> lynx doc/manual/strchan.html
     $> info doc/manual/strchan.info

5 Releases

This is the OpenSS7 Release of the OpenSS7 STREAMS Channels tools, drivers and modules used with the Linux Fast-STREAMS or Linux STREAMS¹⁰ SVR 4.2 STREAMS releases.

The purpose of providing a separate release of this package was to separate the OpenSS7 STREAMS Channels tools, headers, drivers and modules from the Linux STREAMS¹¹ package for use with both Linux STREAMS¹² and Linux Fast-STREAMS in preparation for replacement of the former by the later.

The following sections provide information on OpenSS7 STREAMS Channels releases as well as compatibility information of OpenSS7 release to mainstream UNIX releases of the core, modules and drivers, as well as Linux kernel compatibility.

5.1 Prerequisites

The quickest and easiest way to ensure that all prerequisites are met is to download and install this package from within the OpenSS7 Master Package, openss7-0.9.2.F, instead of separately.

Prerequisites for the OpenSS7 STREAMS Channels package are as follows:

1. Linux distribution, somewhat Linux Standards Base compliant, with a 2.4 or 2.6 kernel and the appropriate tool chain for compiling out-of-tree kernel modules. Most recent Linux distributions are usable out of the box, but some development packages must be installed. For more information, see Compatibility.

   	− A fairly LSB compliant GNU/Linux distribution.13
   	− Linux 2.4 kernel (2.4.10 - 2.4.27), or
   	− Linux 2.6 kernel (2.6.3 - 2.6.21);
   	− glibc2 or better.
   	− GNU info (for info files).
   	− GNU groff (for man pages).14

(Note: If you acquired strchan a part of the OpenSS7 Master Package, then the dependencies listed below will already have been met by unpacking the master package.)

2. OpenSS7 Linux Fast-STREAMS, streams-0.9.2.3. ¹⁵
3. OpenSS7 STREAMS Compatibility Modules, strcompat-0.9.2.6.
4. OpenSS7 STREAMS XNS, strxns-0.9.2.6.

If you need to rebuild the package from sources with modifications, you will need a larger GNU tool chain as described in See Downloading from CVS.

5.2 Compatibility
