NAME

SS7 - OpenSS7 SS7 Devices

SYNOPSIS

#include <sys/stream.h>

int ss7_stream = open(ss7_device, flags);
int retval = ioctl(ss7_stream, I_PUSH, ss7_module);

DESCRIPTION

Devices

SS7[1]
provides the following STREAMS pseudo-device drivers:

isup(4): SS7 Integrated Services Digital Network (ISDN) User Part (ISUP)[2..5] protocol layer that provides a Call Control Interface, cci(7), for ISUP operation, cci_isup(7), and an IO Control Interface, lmi_ioctl(4), for ISUP operation, isup_ioctl(4).
bicc(4): SS7 Bearer Independent Call Control (BICC)[6] protocol layer that provides a Call Control Interface, cci(7), for BICC operation, cci_bicc(7), and an IO Control Interface, lmi_ioctl(4), for BICC operation, bicc_ioctl(4).
tcap(4): SS7 Transaction Capabilities Application Part (TCAP)[7..11] protocol layer that provides a TCAP, tcapi(7), TPI interface, tpi(7), for TCAP operation, tpi_tcap(7), and XTI interface, xti(3), for TCAP operation, xti_tcap(3), and an IO Control Interface, lmi_ioctl(4), for TCAP operation, tcap_ioctl(4).
sccp(4): SS7 Signalling Connection Control Part (SCCP)[12..16] protocol layer that provides an SCCP, sccpi(7), NPI interface, npi(7), for SCCP operation, npi_sccp(7), TPI interface, tpi(7), for SCCP operation, tpi_sccp(7), and XTI interface, xti(3), for SCCP operation, xti_sccp(3), and an IO Control Interface, lmi_ioctl(4), for SCCP operation, sccp_ioctl(4).
mtp(4): SS7 Message Transfer Part (MTP) Level 3[17] protocol layer that provides an MTP, mtpi(7), NPI interface, npi(7), for MTP operation, npi_mtp(7), TPI interface, tpi(7), for MTP operation, tpi_mtp(7), and XTI interface, xti(3), for MTP operation, xti_mtp(3), and an IO Control Interface, lmi_ioctl(4), for MTP operation, mtp_ioctl(4).

Modules

SS7[1] provides the following pushable STREAMS modules:

sl(4): Signalling Link Interface[18], sli(7), module that can be pushed on a stream that conforms to the Signalling Data Terminal Interface, sdti(7). It also provides a Communications Device Interface, cdi(7), or Data Link Provider Interface, dlpi(7). for SS7 MTP2 Links.
sdt(4): Signalling Data Terminal Interface[19], sdti(7), module that can be pushed on a stream that conforms to the Signalling Data Link Interface, sdli(7).
sdl(4): Signalling Data Link Interface[20], sdli(7), module that can be pushed on a stream that conforms to the Channel Interface, chi(7).

Drivers

SS7[1] support is provided for the following STREAMS device drivers:

acb56(4): ACB56 V.35 card driver that provides a Signalling Data Terminal, sdti(7), interface. sl(4), modules can be pushed over this device to provide the MTP Level 3 Signalling Link, sli(7), interface.
x400p(4): T400P-SS7 and E400P-SS7 4-span T1/E1 card driver that provides a Channel, chi(7), Multiplex, mxi(7), Signalling Data Link, sdli(7), Signalling Data Terminal, sdti(7), and Signalling Link, sli(7) interface. sdt(4), and sl(4) modules can be pushed over the sdli(7) device to form a complete SS7 MTP Level 2 signalling link, or the sli(7) interface can be used directly.
x100p(4): T100P-SS7 and E100P-SS7 1-span T1/E1 card driver that provides a Channel, chi(7), Multiplex, mxi(7), Signalling Data Link, sdli(7), Signalling Data Terminal, sdti(7), and Signalling Link, sli(7) interface. sdt(4), and sl(4) modules can be pushed over the sdli(7) device to form a complete SS7 MTP Level 2 signalling link, or the sli(7) interface can be used directly.

NOTICES
