freebsd-dev/usr.sbin/i4b/isdnd/isdnd.rc.5
Poul-Henning Kamp 19c749625f Initial entry of ISDN4BSD into the FreeBSD tree.
ISDN4BSD is the work of our brand-new comitter: Hellmuth Michaelis,
who has done a tremendous amount of work to bring us this far.

There are still some outstanding issues and files to bring into
the tree, and for now it will be needed to pick up all the extra
docs from the isdn4bsd release.

It is probably also a very good idea to subscribe to the isdn@freebsd.org
mailing list before you try this out.

These files correspond to release "beta Version 0.70.00 / December
1998" from Hellmuth.

.Sh NAME
.Nm isdnd.rc
.Nd isdn4bsd ISDN connection management daemon config file format
.Sh DESCRIPTION
The file
.Pa /etc/isdn/isdnd.rc
contains (if not otherwise specified on the command line) the runtime
configuration for the
.Xr isdnd 8
ISDN connection management daemon which is part of the isdn4bsd package.
.Pp
The configuration file consists of keywords which start in column 1 followed by
one or more spaces or tabs, an equal sign, one or more spaces or tabs
and a keyword dependent parameter value.
.Pp
A line beginning with '#' is treated as a comment line.
.Pp
For keywords requiring the specification of a boolean value, the truth
value can be either
.Em yes
or
.Em on
while the false value can be either
.Em no
or
.Em off .
.Pp
The configuration file consists of one
.Em system
section and one or more
.Em entry
sections.
In the
.Em system
section parameters regarding the daemon operation or parameters
not associated with a single remote connection can be set.
In the
.Em entry
section(s) parameters directly associated with a single remote
connection can be set.
.Pp
The following keywords are recognized by
.Nm isdnd :
.Pp
.Bl -tag -width system -compact
.It Li system
This keyword starts the system configuration section. It must not
have a parameter and may be used only once. The keyword is mandatory.
The following keywords are valid in the system configuration section:
.Bl -tag -width useacctfile -compact
.It Li acctall
If this parameter is set to
.Em on ,
accounting information is written even if the local site was not charged
or no charging information is available or is not subscribed. (optional)
.It Li acctfile
Specifies the name of the accounting file which is used when the keyword
.Em useacctfile
(see below) is set to
.Em on .
If this keyword is omitted the system default is used. (optional)
.It Li aliasing
If this parameter is set to
.Em on ,
alias processing of telephone-number to name is enabled (see also the
.Em aliasfile
keyword below). The default is off. (optional)
.It Li aliasfile
Specifies the name of the telephone number-to-name alias database file shared
with the
.Xr isdntel 1
utility when alias processing is enabled via the
.Em aliasing
keyword. (optional)

If this parameter is set to
.Em on ,
date/time information from the exchange (if provided) is written to the
logfile. The default is off. (optional)
.It Li monitor-allowed
If this parameter is set to
.Em on
or
.Em yes ,
monitoring via a local or remote machine is enabled.
This parameter is optional and is set to
.Em off
by default.
.It Li monitor-port
sets the TCP port number for remote monitoring.
This integer parameter is optional and is set to port 451 by default.
.It Li monitor
This keyword specifies a local socket name or a host or network for remote
monitoring. The
.Em monitor
specification may either be:
.Pp
.Bl -tag -width Ds -compact -offset
.It Ar the name of a local (UNIX-domain) socket
this MUST start with a "/", example: /var/run/isdn-monitor
.It Ar a dotted-quad host specification
example: 192.168.1.2
.It Ar a dotted-quad network address with netmask
example: 192.168.1.0/24
.It Ar a resolvable host name
example: localhost
.It Ar a resolvable network name with netmask

.It Ar callin
.It Ar callout
.El
.It Li ratesfile
Specifies the name of the ratesfile. If this keyword is omitted the system
default is used. (optional)
.It Li regexpr
This keyword is used to specify regular expressions. It can be specified
more than once up to a compile time dependent value (currently set to 5 by
the MAX_RE definition in the source).
.Pp
All specified regular expressions are compared to the log strings at runtime
and if a match is found, a program is run with the log text as a parameter
(see also the keyword
.Em regprog
below).
.Pp
For an explanation how regular expressions are specified, please have a
look at
.Xr re_format 7
and
.Xr regex 3 .
The
.Em extended
regular expression syntax is supported here.
.Pp
Hint: it might be necessary to properly quote the expression to avoid
improper interpretation by the configuration file parser.
(optional)
.It Li regprog
This keyword is used to specify the name of a program which is run in
case a corresponding regular expression is matched by a logging string.

(optional)
.It Li rtprio
Specifies the realtime priority
.Nm isdnd
runs at as an integer value in the range 0...31 with 0 being the highest
priority. This keyword is optional; if not specified the process priority of

us back.
.El
.It Li dialrandincr
When dialing or re-dialing and this parameter is set to

.Em downtime
seconds).
(see also the keyword
.Em usedown
further up). This keyword is optional.

channel is acceptable). Thus the exchange is still free to select another
than the requested channel!
(mandatory)
.It Li isdntxdel-incoming
A delay value suitable for the
.Em timeout()
kernel subroutine to delay the transmittion of the first packet after a
successfull connection is made by this value for
.Em incoming
ISDN connections. The specification unit is 1/100 second. A zero (0) disables
this feature and is the default value. This feature is implemented (and makes

with the
.Em "Called Party Number Information Element"
got from the telephone exchange.
.Pp
This keyword is mandatory for the ipr interfaces.
.It Li name
Defines a symbolic name for this configuration entry. It's purpose is to
use this name in the full-screen display for easy identification of a link
to a remote site and for accounting purposes. (mandatory)
.It Li ratetype
The rate entry used from the rates file. (optional)
.br
For example, ratetype=0 selects lines beginning "ra0" in /etc/isdn/isdnd.rates;

.It Ar next
For every new (non-retry) call setup, start with the next number which
follows the last one used.
.El
.It Li remote-phone-dialout
The remote telephone number used when the local site dials out. When dialing
out to a remote site, the number specified here is put into the
.Em "Called Party Number Information Element" .

This keyword is mandatory for the
.em
ipr
interfaces. It may be specified more than once to try to dial to several
numbers until one succeeds.
.It Li remote-phone-incoming
The remote telephone number used to verify an incoming call. When a remote site
dials in, this number is used to verify that it is the correct remote site
which is herewith authorized to connect into the local system. This parameter
is compared against the
.Em "Calling Party Number Information Element"
got from the telephone exchange.
.Pp
This keyword is mandatory for the ipr interfaces.
.Pp
This keyword may have a wildcard parameter '*' to permit anyone dialing in.
.It Li unitlength
The length of a charging unit in seconds. This is used in conjunction with
the idletime to decide when to hangup a connection. (optional)
.It Li unitlengthsrc
This keyword is used to specify from which source
.Xr isdnd 8

Use the unitlength specified on the commandline.
.It Ar conf
Use the unitlength specified in the configuration file with the keyword
.Em unitlength .
.It Ar rate
Use the unitlength from the ratesfile specified in the configuration
file with the keyword
.Em ratetype .

which is a service provided by the telecommunications (ie phone) provider,
to indicate billable units).
.El
.It Li usrdevicename
Specifies the userland interface which is used for interfacing ISDN B channel
data to the userland. The keyword is mandatory.
This keyword accepts the following parameters:
.Pp
.Bl -tag -width Ds -compact -offset
.It Ar ipr

This specifies a Raw B CHannel access interface.
.It Ar tel
ISDN telephony.
.El
.It Li usrdeviceunit
Specifies the unit number for the with the
.em
usrdevicename
specified device.
.It Li usedown
is used to enable the use of the keywords
.Em downtries
and
.Em downtime
in the entries section(s). It is used in the
.Nm isdnd
daemon to dynamically enable and disable the IP interfaces to avoid excessive
dialing activities in case of transient failures (such as busy lines).
This parameter is optional and is set to
.Em off
by default.
.It Li connectprog
specifies a program run everytime after a connection is established and
address negotiation is complete (i.e.: the connection is useable).

.Sh IDLETIME CALCULATION AND SHORTHOLD MODE
.Bl -tag -width incoming calls -compact
.It Li incoming calls
It is assumed that the calling side knows most about charging structures and
such and as a consequence only the keyword
.Em idletime-incoming
has a function for incoming calls.
.Pp
For incoming calls the line is constantly monitored, and in case there was
not traffic taking place for the time in seconds specified by
.Em idletime-incoming
the call is closed.
.Pp
Typically,
.Em idletime-incoming
is used as a last resort and is therefore set much higher than a charging
unit time: typical values are one to five minutes.
.It Li outgoing calls
Outgoing call disconnect time can be setup in one of two ways:
.Bl -tag -width shorthold mode -compact
.It Li simple mode
For simple mode, the selected
.Em unitlength
must be 0 (zero) and
.Em idletime-outgoing
greater zero.
.Pp
The outgoing traffic is constantly monitored, and in case there was
not traffic taking place for the time in seconds specified by
.Em idletime-outgoing
the call is closed.
.Pp
Typical values in simple mode are 10 to 30 seconds.
.It Li shorthold mode
For shorthold mode, the selected
.Em unitlength
and
.Em idletime-outgoing
must be greater than 0 (zero);
.Em earlyhangup must be >= 0 (zero).
.Bd -literal
|<unchecked-window>|<checkwindow>|<safetywindow>|
| | | |
+------------------+-------------+--------------+
| | | |
| |<-idle-time->|<earlyhangup->|
|<--------------unitlength--------------------->|
.Ed
During the unchecked window which is (unitlength - (idle-time+earlyhangup))
in length, no idle check is done. After the unchecked window has ended,
the line is checked for idle-time length if no traffic takes place. In case
there was traffic detected in the check-window, the same procedure is restarted
at the beginning of the next unit. In case no traffic was detected during
the check-window, the line is closed at the end of the check window.
.Pp
Notice:
.Em unitlength
must (!) be greater than the sum of
.Em idletime-outgoing
and
.Em earlyhangup !
