T400P-SS7, E400P-SS7 Device Driver

The T400P-SS7 (T1) and E400P-SS7 (E1) cards are affordable 4-Span T1 and E1 cards manufactured by Digium under an open hardware design (Gerber plots available) and resold by OpenSS7 Corporation. The proceeds of the sale of these cards go directly to the support of the OpenSS7 Project.

The X400P-SS7 driver provides SS7, ISDN and voice channel support for these cards. The driver provides the following interfaces:

Local Management Interface (LMI)

Signalling Data Link Interface (SDLI)

Signalling Data Terminal Interface (SDTI)

Signalling Link Interface (SLI)

Data Link Provider Interface (DLPI)

Multiplex Interface (MXI)

Channel Interface (CHI)

For more information on card specifications see our hardware page for the card here.

Work on this driver was started April 2002.

The X400P-SS7 driver is in the Maintenance stage.

Varion has provided the project with a complimentary (partially populated) V400P (E1) card for testing.

This component depends on the following interfaces:

Local Management Interface (LMI)

Signalling Data Link Interface (SDLI)

Signalling Data Terminal Interface (SDTI)

Signalling Link Interface (SLI)

Data Link Provider Interface (DLPI)

Multiplex Interface (MXI)

Channel Interface (CHI)

This device driver is a Linux 2.4.x loadable module which depends upon the PCI facilities of the Linux 2.4.x kernel series.
