NAME

acb56 - SeaLevel ACB56 Device Driver

SYNOPSIS

#include <ss7/lmi.h>
#include <ss7/lmi_ioctl.h>
#include <ss7/sdli.h>
#include <ss7/sdli_ioctl.h>
#include <ss7/sdti.h>
#include <ss7/sdti_ioctl.h>
#include <sys/stropts.h>

int retval = ioctl(acb56_stream, I_PUSH, ``sl'');

DESCRIPTION

ACB56
is a Signalling Data Terminal Interface, sdti(7), device driver for the SeaLevel Systems, Inc., ACB56 card.

ACB56 is implemented as a STREAMS(4) device driver that provides the Signalling Data Terminal Interface, sdti(7).

ACB56 provides the following devices that are directly compatible with the stream types provided by pushing the sdt(4) module:

/dev/acb56: This device provides an SDT protocol service interface using the SDT-primitives of the Signalling Data Terminal Interface described in sdti(7). This interface is suitable for use with the sl(4) module for use with the mtp(4) or m2ua(4) multiplexors.

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 acb56_stream file descriptor. See sdt_ioctl(4) for a complete description of SDT management controls, and below for a description of SDT management controls particular to the ACB56 driver.

NOTICES

ACB56 supports all of the management IO controls described in sdt_ioctl(4), with the following exceptions:

---: ACB56 does not support the flags, f, field of the sdt_config structure. The number of flags between frames is under the control of the SCC chip on the card.
---: ACB56 does not support the transmit block size, b, field of the sdt_config structure.
---: ACB56 does not support the following fields of the sdt_config structure: t8, Te, De and Ue, as it does not support high speed links.
---: ACB56 does not support the protocol options SS7_POPT_HSL, SS7_POPT_XSN and SS7_POPT_ALL, values in the popt field of the sdt_opt_conf structure, as it does not support high speed links.
---: ACB56 does not support the eim_state, Ce, su_received or interval_error, fields of the sdt_statem structure, as it does not support high speed links.
---: ACB56 does not support the carrier_lost field of the sdt_stats structure, as it does not support common carrier modes.
