.Dd January 8, 2002 .Dt SBNI 4 i386 .Os FreeBSD .Sh NAME .Nm sbni .Nd Granch SBNI12 leased line modem driver .Sh SYNOPSIS .Cd "device sbni" .Sh DESCRIPTION The .Nm sbni driver provides support for leased line modems of following models:
p l -tag -compact t Pa SBNI12-02, SBNI12D-02 t Pa SBNI12-04, SBNI12D-04 t Pa SBNI12-05, SBNI12D-05, ISA and PCI t Pa SBNI12-10, SBNI12D-10, ISA and PCI .El
p and a kit for data link over a voice band SBNI12-11, SBNI12D-11, ISA and PCI.
p In addition to the standard port and irq specifications, the .Nm driver also supports a number of .Em flags which can set baud rate, receive level, and low three bytes of Ethernet MAC-address (high three always are 00:ff:01), because Granch modems is presented to the system as Ethernet-like netcards.
p The high byte of the .Em flags is a bit field, it's used to specify SBNI adapter receive level/baud rate: d -literal Bits 0-3: receive level (0x00..0x0f) Bits 4-5: baud rate number: 00 - 0 baud rate (2Mb in fast mode/500kb in slow) 01 - 1 baud rate (1Mb/250kb) 10 - 2 baud rate (500kb/125kb) 11 - 3 baud rate (250kb/62.5kb) Bit 6 : use fixed receive level if bit 6 is set then receive level will be set according to bits 0-3 value, otherwise receive level will be autodetected Bit 7 : use fixed baud rate if bit 7 is set then baud rate will be set according to bits 4-5 value, otherwise baud rate is set to 2Mb .Sh FILES The sources for the driver reside in:
p l -tag -compact t Pa /sys/dev/sbni/if_sbni.c t Pa /sys/dev/sbni/if_sbnireg.h t Pa /sys/dev/sbni/if_sbnivar.h .El .Sh SEE ALSO .Xr arp 4 , .Xr netintro 4 , .Xr ifconfig 8 .Sh HISTORY The .Nm device driver first appeared in .Fx 4.6 . .Sh AUTHORS The .Nm sbni device driver for FreeBSD 4.x was written by Denis I. Timofeev, partially based on David Greenman's .Nm ed driver. Earlier versions (available on ftp.granch.com) were written by Alexey V. Zverev.
p SBNI12 hardware was designed by Alexey V. Chirkov.
