DESCRIPTION

X400P
is a device driver for the Digium T400P and X400P 4-span T1/E1 PCI cards.

X400P is implemented as a STREAMS(4) device driver that provides the Signalling Data Link Interface, sdli(7), Signalling Data Terminal Interface, sdti(7), Signalling Link Interface, sli(7), Channel Interface, chi(7), and Multiplex Interface, mxi(7). The sdli(7), sdti(7), and sli(7), interface can be used directly, or the sdl(4), sdt(4), and sl(4), modules can be pushed over a Channel Interface, chi(7).

X400P provides the several devices that are directly compatible with a number of stream types and interface protocols. To select a stream type, x400p_device can be selected from the following devices:

/dev/x400p-ss7: This device provides an SDL, SDT, and SL, protocol service interface using SDL-, SDT- and SL-primitives of the sdli(7), sdti(7), or sli(7). This interface is suitable to be usde directly as an sdli(7) device, or have an sdt(4), or sl(4), module pushed over the sdli(7) or sdti(7) interfaces. At the sli(7) interface level, this device is suitable to be linked under an mtp(4) or m2ua(4) mulitplexor. The only bearer channel access that this device provides is using the sdli(4) interface.
/dev/x400p-ch: This device provides a CH and MX protocol service interface using CH- and MX-primitives of the chi(7) and mxi(7). The mxi(7). interface to this device is suitable to be linked under a Media Gateway mg(4), multiplexor for complete bearer channel switching and control. The chi(7) interface to this device is suitable to have sdl(4), sdt(4) and sl(4) modules pushed over the channel to provide a Signalling Link Interface, sli(7) stream that can be then linked under a mtp(4) or m2ua(4) multiplexor for SS7(4) support.

The /dev/x400p-ss7 and /dev/x400p-ch drivers are separate loadable modules and cannot be loaded at the same time. /dev/x400p-sss7 is the older vintage driver that supported SS7 with meager support for bearer channel access. /dev/x400p-ch is the newer vintage channel driver that provides complete support for bearer channel access and uses pushable modules over a Channel Interface, chi(7), to support SS7. These modules are the sdl(4), sdt(4), and sl(4) modules.

IOCTLS

All interfaces support a set of Local Management Interface IO controls, lmi_ioctl(4), using the ioctl(2) and I_STR command to the streamio(2) system call on the x400p_stream file descriptor. The /dev/x400p-ss7 device supports the SS7 Local Management Interface IO controls at the sdl_ioctl(4), sdt_ioctl(4), and sl_ioctl(4), levels. The /dev/x400p-ch devices supports the MG Local Management Interface IO controls at the ch_ioctl(4), and mx_ioctl(4), levels. This driver uses the sdl(4), sdt(4), and sl(4) modules to support the SS7 Local Management Interface IO controls.

NOTICES

The X400P /dev/x400p-ss7 device supports all of the management IO controls described in sdl_ioctl(4), sdt_ioctl(4) and sl_ioctl(4), with the following exceptions:

The X400P /dev/x400p-ch device supports all of the management IO controls described in ch_ioctl(4), and mx_ioctl(4), with the following exceptions:

---
---

NOTICES

The /dev/x400p-ss7 device driver is deprecated. For new applications use the /dev/x400p-ch driver and push the sdl(4), sdt(4), and sl(4), modules.

BUGS

Two drivers is confusing and the deprecated driver must be removed.

VERSIONS

This manpage was updated 2008-10-31 for strss7 release 0.9a.8.

The X400P driver is specific to the OpenSS7 SS7(4) and ISDN(4) stacks. The X400P driver will first appear in strss7-0.8.4. At that time, the deprecated /dev/x400p-ss7 driver will be removed.
