SYNOPSIS

int sigtran_stream = open(sigtran_device, flags);

DESCRIPTION

SS7 Devices

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

bua(4): SS7 BICC User Adaptation Layer (BUA) protocol layer transporting and distributing the services provided by bicc(4) and providing an IO Control interface, lmi_ioctl(4), for BUA-specific management, bua_ioctl(4).
isua(4): SS7 ISUP User Adaptation Layer (ISUA)[2] protocol layer transporting and distributing the services provided by isup(4) and providing an IO Control interface, lmi_ioctl(4), for ISUA-specific management, isua_ioctl(4).
tua(4): SS7 TCAP User Adaptation Layer (TUA)[3] protocol layer transporting and distributing the services provided by tcap(4) and providing an IO Control interface, lmi_ioctl(4), for TUA-specific management, tua_ioctl(4).
sua(4): SS7 SCCP User Adaptation Layer (SUA)[4] protocol layer transporting and distributing the services provided by sccp(4) and providing an IO Control interface, lmi_ioctl(4), for SUA-specific management, sua_ioctl(4).
m3ua(4): SS7 MTP3 User Adaptation Layer (M3UA)[5] protocol layer transporting and distributing the services provided by mtp(4) and providing an IO Control interface, lmi_ioctl(4), for M3UA-specific management, m3ua_ioctl(4).
m2ua(4): SS7 MTP2 User Adaptation Layer (M2UA)[6] protocol layer transporting and distributing the services provided by sl(4) and providing an IO Control interface, lmi_ioctl(4), for M2UA-specific management, m2ua_ioctl(4).

SS7 Modules

SIGTRAN provides the following SS7 modules:
