NAME
     itester - ISDN test and development tool

SYNOPSIS
     /usr/etc/itester [-x] -t switch_software_type [ -s spid1 ] [ -S spid2 ] [
     -r rate1 ] [ -R rate2 ] -c calldn1 [ -C calldn2 ]


DESCRIPTION
     itester is used during ISDN layer 1 certification testing to turn on the
     IOM loop in the hardware.  It can also be used for developing additional
     ISDN stack functionality.

OPTIONS
     -x      When this is specified, itester is able to establish data links,
             register spids, and make and receive calls.  If it is not
             specified, itester can only control the loopback.  For ISDN layer
             1 testing, itester should be started without this option.

     -t switch_software_type
             switch_software_type must be one of DMS100, NI1, 5ESS, NET3,
             1TR6, or NTT.

     -s spid1
             This option specifies the first SPID.  This option is only needed
             for the DMS100 and National ISDN 1 (NI1) switch software types.

     -S spid2
             This option specifies the second SPID.  This option is only
             needed for the DMS100 and National ISDN 1 (NI1) switch software
             types.

     -r rate1
             Specifies the connection rate of channel B1.  If 56, then the B1
             SETUP will be sent asking for a 56kbps connection.  If 64 or not
             specified, then the B1 SETUP will be sent asking for a 64 kbps
             connection.

     -R rate2
             Specifies the connection rate of channel B2.  If 56, then the B2
             SETUP will be sent asking for a 56kbps connection.  If 64 or not
             specified, then the B2 SETUP will be sent asking for a 64 kbps
             connection.

     -c calldn1
             Specifies the phone number to call on channel B1.  This must be
             specified.

     -C calldn2
             Specifies the phone number to call on channel B2.


Use
     To use itester during ISDN Layer 1 certification testing, first start
     isdnd.  Then start itester without the -x option.  During layer 1
     testing, the testing technician may ask you to turn on loopback.  To turn
     on loopback, press '4'.  Itester has no other function during Layer 1
     testing.

     To use itester for development or testing purposes, do not start isdnd.
     Start itester with the -x option.  Enter spids and dns as neccessary.
     First build a protocol stack (you may not want any protocol stack, lapd
     only, or the entire stack.)  To put lapd on the stack, press '8'.  To put
     the Q931 modules on the stack, press 'p'.  If you are using a switch
     software type that requires 2 spids, then you should also press 'P'.  (In
     the menu, all lower case letters with an asterisk next to it indicates
     that if you press the capital letter, the same action will take place on
     B2.)

     Now activate the hardware by pressing 2.  This takes the hardware out of
     the reset state.  If you just want to establish a data link, press 'e'
     (or 'E' for B2).  If you want to register a spid, press 'i' (or 'I' for
     B2).  To answer a call on B1, press 'a'.  To answer a call on B2, press
     'A'.  The 'a' option toggle, so if you don't want to answer the call on
     B1 anymore, you should press 'a' again.

     The main window of itester provides some useful information about what is
     going on in the protocol stack.  They are not intended for naive ISDN
     users; but they are helpful for people who are working with ISDN.
