# sbsh(4)

Granch SBNI16 SHDSL modem device driver

## NAME

**sbsh** – Granch SBNI16 SHDSL modem device driver

## SYNOPSIS

**device sbsh**

## DESCRIPTION

The **sbsh** driver provides support for an internal PCI modem SBNI16-SHDSL. A device is introduced to the OS as a common Ethernet-like network card which must be configured with [ifconfig(8)](/ifconfig/8.md) (all standard network interface parameters could be set). Modem-specific parameters (master/slave mode, line rate, etc.) must be set with the **sb16config** utility before interface activation.

## FILES

The sources for the driver reside in:

- */sys/dev/sbsh/if\_sbsh.c*

  - */sys/dev/sbsh/if\_sbshreg.h*

  ## DIAGNOSTICS

- sbsh%d: couldn't map memory

  - sbsh%d: couldn't map interrupt

  - sbsh%d: couldn't set up irq

  A fatal initialization error has occurred.

- sbsh%d: unable to load firmware

  A fatal error has occurred while **sb16config** was running.

- sbsh%d: firmware wasn't loaded

  “**ifconfig** *...* **up**” has failed because device has not been configured with **sb16config**.

- sbsh%d: transmit timeout

  - sbsh%d: interrupt posted but not delivered

  Probably, a hardware error or incompatibility.

- sbsh%d: unable to get mbuf

  - sbsh%d: unable to get mbuf cluster

  The driver failed to allocate a memory buffer.
