ACB-56 Device Driver

The ACB56 card is a single V.35 ISA card available from SeaLevel based on the Zilog MPCC chip. These cards available directly from Sealevel.

The ACB56 driver provides SS7 support for these cards. The driver provides the following interfaces:

Local Management Interface (LMI)

Signalling Data Terminal Interface (SDTI)

Signalling Link Interface (SLI)

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

Work on this driver started in January 1999. This driver was moved to the STREAMS version of the OpenSS7 SS7 stack in 2000.

The ACB56 driver is in the Maintenance stage.

If there is sufficient interest, the driver will be enhanced to support the mutliple V.35 PCI cards also available from Sealevel and based on the same Zilog chip.

This component depends on the following interfaces:

Local Management Interface (LMI)

Signalling Data Terminal Interface (SDTI)

Signalling Link Interface (SLI)

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