NAME

     libngatm -- ATM signalling library

LIBRARY

     Begemot ATM signalling library (libngatm, -lngatm)

DESCRIPTION

     The Begemot UNI signalling library handles message decoding and encoding as well as the Q.2110 and Q.2120 transport protocols and adaptation
     layers, and ATM-Forum UNI 4.0 compliant signalling.  Because of this complexity the description is broken down in several man pages:

     unimsg(3)
	   Describes a data structure and functions for handling of variable sized messages.

     unistruct(3)
	   describes data structures for the decoding, encoding and printing functions in the library.

     unifunc(3)
	   describes the decoding, encoding and printing functions.

     uniaddr(3)
	   describes address structures and handling functions.

     unisap(3)

STANDARDS

     This implementation conforms to the applicable ITU-T recommendations and ATM Forum standards.

NAME

     sscop -- SSCOP transport protocol

SYNOPSIS

     sscop [-Fbefhirwx3] [-V X] [-W N] [-a p=v] [-l N] [-t t=m] [-v X]

DESCRIPTION

     The sscop tool implements the Q.2110 transport protocol.  Normally the program reads from standard input and sends this input over the SSCOP
     protocol on the standard output file descriptor. This means, that the standard output file descriptor should be connected in read-write mode.
     The program takes the following arguments:

     -F      Use frameing on the SSCOP connection (see the -f option).

     -V X    Set the verbose flag to the hex value X.

     -W N    Set the initial SSCOP window to N.

     -a p=v  Set SSCOP parameter p to the value v.  The following parameters may be set:

	     j=N     Set the maximum SSCOP-UU data size to N octets.

	     k=N     Set the maximum SSCOP SDU data size to N octets.

	     cc=N    Set the parameter MaxCC (maximum number of connection control message re-transmissions) to the value N.

	     pd=N    Set the parameter MaxPD (maximum acceptable number of outstanding unacknowledged SD PDUs before sending a POLL) to the value
		     N.

	     stat=N  Set the parameter MaxSTAT (maximum number of elements placed in a STAT PDU) to the value N.

     -b      Enable the ATM-Forum SSCOP robustness enhancement.

     -e      Exit when there is an end of file condition on the input file or the SSCOP indicates a release confirmation.

     -f      Use the framing protocol for communication over the SSCOP link. See frame(l) (libbegemot) for framing.

     -h      Print a short help information and exit.

     -i      Try not to read from the user input file descriptor. Assume that we a receiving only.

     -l N    Loose every Nth message. This is used for testing.

     -r      Revert user and SSCOP file descriptors. That means, that user input and output is done on standard output and SSCOP input and output
	     on standard input.

     -t t=m  Set SSCOP timer t to m milliseconds. The following timers may be set:

	     cc=m    Set the connection control timer to m.  This timer controls the retransmission of connection control messages.

	     poll=m  Set the poll timer to m.  This timer controls the transmission of POLL messages.

	     ka=m    Set the keep-alive timer to m.  This timer controls the maximum length of the transient phase.

	     nr=m    Set the no-response timer to m.  This timer controls the maximum time between two received STAT PDUs before the connection is
		     aborted.

	     idle=m  Set the idle timer to m.  This timer controls the length of the idle phase.

     -v X    Set the SSCOP library verbose flag to the hex value.

     -w      Don't start the SSCOP protocol. Wait for a establish indication from the remote side.

     -x      Enable to POLL after retransmission flag.

     -3      Send user output to file descriptor 3.

EXAMPLES

     The following command line sends the file Makefile over a pipe (this depends on the feature that pipes are bi-directional):

     cat Makefile | sscop -reF | sscop -weF

STANDARDS

     The implemented protocol conforms to ITU-T recommendation Q.2110.
