NAME

ISDN - OpenSS7 ISDN Devices

SYNOPSIS

#include <sys/stream.h>

int isdn_stream = open(isdn_device, flags);
int retval = ioctl(isdn_stream, I_PUSH, isdn_module);

DESCRIPTION

The ISDN related collection of drivers and modules provide ISDN[1, 2] capabilities in a number of related forms, including H.323, V5.2, GR-303 and GSM variants.

DRIVERS

ISDN provides the following STREAMS pseudo-device drivers:

isdn(4): Integrated Services Digital Network (ISDN) Q.931/932 Network Layer protocol layer[3, 4] that provides a Call Control Interface, cci(7), for ISDN operation, cci_isdn(7), and a Local Management Interface, lmi_ioctl(4), for ISDN management, isdn_ioctl(4).
capi(4): Common ISDN Application Programming Interface (CAPI)[5] protocol layer that provides the Call Control Interace, cci(7), for ISDN operation, cci_isdn(7), for CAPI devices installed and registered on the local system, and a Local Management Interface, lmi_ioctl(4), for CAPI management, capi_ioctl(4).
v5(4): V5.2 protocol layer that provides the Call Control Interface, cci(7), for V5.2 operation, v5_ioctl(4).
gr303(4): GR-303-CORE protocol layer that provides the Call Control Interface, cci(7), for GR-303-CORE operation, cci_gr303(7), and a Local Management Interface, lmi_ioctl(4), for GR-303-CORE management, gr303_ioctl(4).
dl(4): Q.921 (LAPD), Q.922 (LAPF), X.25 (LAPB)[6..8], Data Link Provider Interface, dlpi(7), for LAPD, LAPF and LAPB, dlpi_lapd(7), dlpi_lapf(7), dlpi_lapb(7), and a Local Management Interface, lmi_ioctl(4), for DL management, dl_ioctl(4).

MODULES

ISDN provides the following pushable STREAMS modules:

hdlc(4): ISO 3309/4335 High-Level Data Link Control (HDLC)[9, 10] Communications Device Interface, cdi(7), module, that can be pushed over a stream that conforms to the Channel Interface (CHI), chi(7).

DEVICES

ISDN provides the following STREAMS device drivers:

x400p(4): T400P-SS7 and E400P-SS7 4-span T1/E1 card driver that provides a Channel Interface, chi(7), and Multiplex Interface, mxi(7). The hdlc(4), module cam be pushed over the chi(7) device and linked under the dl(4) driver to form a complete ISDN Q.921 data link. The mxi(7) device can be used to switch bearer channels, see mx(4).
x100p(4): T100P-SS7 and E100P-SS7 1-span T1/E1 card driver that provides a Channel Interface, chi(7), and Multiplex Interface, mxi(7). The hdlc(4), module cam be pushed over the chi(7) device and linked under the dl(4) driver to form a complete ISDN Q.921 data link. The mxi(7) device can be used to switch bearer channels, see mx(4).

NOTICES

The hdlc(4) device is now provided by the striso(5) package. lapb(4) and lapf(4) are also provided by the striso(5) package. lapd(4) is still provided by the strisdn(5) package.

VERSIONS

This manpage was updated 2008-10-31 for strisdn release 0.9.2.4.

Most of the devices and modules listed here do no appear until strss7-0.8.4.
