    NAME

    
    
    isdnd.rc
    
     - isdn4bsd ISDN connection management daemon config file format
    
     
    

    DESCRIPTION

    The file /etc/isdn/isdnd.rc contains (if not otherwise specified on the command line) the runtime configuration for the isdnd(8) ISDN connection management daemon which is part of the isdn4bsd package.

    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.

    A line beginning with '#' is treated as a comment line.

    For keywords requiring the specification of a boolean value, the truth value can be either yes or on while the false value can be either no or off

    The configuration file consists of one system section, one or more optional controller sections and one or more entry sections.    #include <the>
    system section parameters regarding the daemon operation or parameters not associated with a single remote connection can be set.    #include <the>
    controller section parameters regarding a particular controller can be set.    #include <the>
    entry section(s) parameters directly associated with a single remote connection can be set.

    The following keywords are recognized by isdnd

    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:

    acctall
    If this parameter is set to on accounting information is written even if the local site was not charged or no charging information is available or is not subscribed. (optional)
    acctfile
    Specifies the name of the accounting file which is used when the keyword useacctfile (see below) is set to on See also system keyword rotatesuffix If this keyword is omitted the system default is used. (optional)
    add-prefix
    If set to on for incoming numbers, have a look at the "type of number" indicator and adjust the number as specified by the prefix-national and prefix-international keywords described later. If this keyword is omitted, the system default (off) is used. (optional)
    aliasing
    If this parameter is set to on alias processing of telephone-number to name is enabled (see also the aliasfile keyword below). The default is off. (optional)
    aliasfile
    Specifies the name of the telephone number-to-name alias database file shared with the isdntel(8) utility when alias processing is enabled via the aliasing keyword. (optional)
    beepconnect
    In full-screen mode, if this parameter is set to on ring the bell when connecting or disconnecting a call.
    extcallattr
    If this parameter is set to on the extended caller attributes "screening indicator" and "presentation indicator" are written to the log-file. The default is off. (optional)
    holidayfile
    Specifies the name of the holiday file containing the dates of holidays. This file is used in conjunction with the valid keyword to lookup the dates of holidays. (optional)
    isdntime
    If this parameter is set to on date/time information from the exchange (if provided) is written to the log-file. The default is off. (optional)
    mailer
    This keyword is used to specify the path/name of a mail program which is able to use the "-s" flag to specify a subject on its command line. In case of a fatal error exit of this program is used to send mail to an administrator specified by the keyword mailto (optional)
    mailto
    This keyword is used to specify the email address of someone to notify in case of a fatal error exit of . (See also keyword mailer ) (optional)
    monitor-allowed
    If this parameter is set to on or yes monitoring via a local or remote machine is enabled. This parameter is optional and is set to off by default.
    monitor-port
    sets the TCP port number for remote monitoring. This integer parameter is optional and is set to port 451 by default.
    monitor
    This keyword specifies a local socket name or a host or network for remote monitoring. The monitor specification may either be:

    the name of a local (UNIX-domain) socket
    this MUST start with a "/", example: /var/run/isdn-monitor
    a dotted-quad host specification
    example: 192.168.1.2
    a dotted-quad network address with netmask
    example: 192.168.1.0/24
    a resolvable host name
    example: localhost
    a resolvable network name with netmask
    example: up-vision-net/24

    monitor-access
    This keyword specifies the access rights for a previously used monitor keyword. The supported access rights are:

    fullcmd
    restrictedcmd
    channelstate
    logevents
    callin
    callout

    prefix-international
    In conjunction with the add-prefix switch (see above), specify the prefix number string for incoming numbers with the international number tag. If aliases are used, they have to be adjusted accordingly. (optional)
    prefix-national
    In conjunction with the add-prefix switch (see above), specify the prefix number string for incoming numbers with the national number tag. If aliases are used, they have to be adjusted accordingly. (optional)
    ratesfile
    Specifies the name of the ratesfile. If this keyword is omitted the system default is used. (optional)
    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).

    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 regprog below).

    For an explanation how regular expressions are specified, please have a look at re_format7 and regex(3). The extended regular expression syntax is supported here.

    Hint: it might be necessary to properly quote the expression to avoid improper interpretation by the configuration file parser. (optional)

    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. Isdnd expects to find the program below the path /etc/isdn which is prepended to the string specified as a parameter to this keyword. (optional)
    rotatesuffix
    Specifies a suffix for renaming the log- and the accounting-filename.    #include <case>
    rotatesuffix is used and a USR1 signal is sent to isdnd, the log-file and the accounting file is not only closed and reopened but the old log-file is also renamed to the former filename with the rotatesuffix string appended. If this keyword is omitted, the log-files are just closed and reopened; this is also the default behavior. (optional)
    rtprio
    Specifies the real-time priority 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 isdnd is not touched in any way. ( See also rtprio(1)). This keyword is only available if was compiled with -DUSE_RTPRIO.

    d64s
    An ISDN leased line with a single B-channel (called D64S in Germany).

    firmware
    This keyword is used like firmware = /path/to/file to download the firmware to active controllers supported by the iavc driver (AVM B1, T1). This keyword is supported for all controller types, and causes I4B_CTRL_DOWNLOAD ioctl to be invoked with the specified file as an argument. In systems equipped with both active and passive adapters, and the passive cards being detected first, dummy `controller' entries are required for the passive cards to get the correct firmwares to correct adapters.

    entry
    This keyword starts one configuration entry. It must not have a parameter. This keyword must be used at least once. The following keywords are valid in an entry section:

    answerprog
    This keyword is used to specify the name of a program which is run in case an incoming telephone connection specified answer in its configuration entry. The default name is answer Isdnd expects to find this program beneath the path /etc/isdn which is prepended to the string specified as a parameter to this keyword. (optional)
    alert
    is used to specify a time in seconds to wait before accepting a call. This keyword is only usable for incoming telephone calls (dialin-reaction = answer). It is used to have a chance to accept an incoming call on the phone before the answering machine starts to run. The minimum value for the alert parameter is 5 seconds and the maximum parameter allowed is 180 seconds. (optional)
    b1protocol
    The B channel layer 1 protocol used for this connection. The keyword is mandatory. The currently configurable values are:

    hdlc
    HDLC framing.
    raw

    Any other value than dov sets the bearer capability as configured by the b1protocol keyword (see above). The currently configurable values are:

    dov
    This connection is a Dov (Data over Voice) connection. The b1protocol keyword must be set to hdlc This feature is experimental and does work on outgoing calls only.

    budget-calloutperiod
    is used to specify a time period in seconds. Within this period, the number of calls specified by budget-calloutncalls are allowed to succeed, any further attempt to call out will be blocked for the rest of the time left in the time period. (optional)
    budget-calloutncalls
    The number of outgoing calls allowed within the time period specified by budget-calloutperiod (optional)
    budget-calloutsfile
    A path/filename to which the number of successful callouts are written. The contents of the file is preserved when it exists during startup of isdnd. The format of this file is: start time, last update time, number of calls. (optional)
    budget-calloutsfile-rotate
    If set to on rotate budget-calloutsfile every night when an attempt is made to update the file on a new day. The statistics for the previous day are written to a file with the filename specified by budget-calloutsfile to which a hyphen and the new day's (!) day of month number is appended. (optional)
    budget-callbackperiod
    budget-callbackncalls
    budget-callbacksfile
    budget-calloutsfile-rotate
    See budget-calloutperiod budget-calloutncalls budget-calloutsfile and budget-calloutsfile-rotate above. These are used to specify the budgets for calling back a remote site.

    calledbackwait
    The time in seconds to wait for a remote site calling back the local site after a call from the local site to the remote site has been made. (optional)
    clone
    This causes the contents of the specified entry to be copied from the existing named entry to the current one. When using this feature at least a new entry specific `name' and `usrdeviceunit' value should be specified for the current entry.
    connectprog
    specifies a program run every time after a connection is established and address negotiation is complete (i.e.: the connection is usable). Isdnd expects to find the program below the path /etc/isdn which is prepended to the string specified as a parameter to this keyword. The programs specified by connect and disconnect will get the following command line arguments: -d (device) -f (flag) [ -a (addr) ] where device is the name of device, e.g. "isp0", flag will be "up" if connection just got up, or "down" if interface changed to down state and addr the address that got assigned to the interface as a dotted-quad ip address (optional, only if it can be figured out by isdnd). (optional)

    Callback behavior, call the remote side which rejects the call and calls us back.

    dialrandincr
    When dialing or re-dialing and this parameter is set to on the dial retry time is added with a random value (currently 0...3 seconds) to minimize the chance of two sites dialing synchronously so each gets a busy each time it dials because the other side is also dialing.
    dialretries
    The number of dialing retries before giving up. Setting this to -1 gives an unlimited number of retries! (optional)
    direction
    This keyword is used to configure if incoming and outgoing, incoming-only or outgoing only connections are possible. The keyword is optional, the default is inout

    The currently supported parameters are:

    inout
    Normal behavior, connection establishment is possible from remote and local.
    in
    Only incoming connections are possible.
    out
    Only outgoing connections are possible.

    disconnectprog
    specifies a program run every time after a connection was shut down. Isdnd expects to find the program below the path /etc/isdn which is prepended to the string specified as a parameter to this keyword. (optional)
    downtries
    is used to configure the number of unsuccessful tries (= retry cycles!) before the interface is disabled (for downtime seconds). (see also the keyword usedown further up). This keyword is optional.
    downtime
    is used to configure the time in seconds an interface is disabled after the configured number of downtries (see also the keyword usedown further up). This keyword is optional and is set to 60 seconds by default.

    A (safety) time in seconds which specifies the time to hang up before an expected next charging unit will occur. (optional)
    idle-algorithm-outgoing
    The algorithm used to determine when to hang up an outgoing call when the line becomes idle. The current algorithms are:

    fix-unit-size
    idle algorithm which assumes fixed sized charging units during the whole call.
    var-unit-size
    idle algorithm which assumes that the charging is time based after the first units time has expired.

    idletime-outgoing
    The time in seconds an outgoing connection must be idle before hanging up. An idle timeout of zero disables this functionality. (optional)
    idletime-incoming
    The time in seconds an incoming connection must be idle before hanging up. An idle timeout of zero disables this functionality. (optional)
    isdncontroller
    The ISDN controller number to be used for connections for this entry. (mandatory)
    isdnchannel
    The ISDN controller channel number to be used for connections for this entry. In case a channel is explicitly selected here, the SETUP message will request this channel but mark the request as preferred (the indicated channel is preferred) instead of exclusive (only the indicated channel is acceptable). Thus the exchange is still free to select another than the requested channel! (mandatory)
    isdntxdel-incoming
    A delay value suitable for the timeout(9) kernel subroutine to delay the transmission of the first packet after a successful connection is made by this value for 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 sense only) for the i4bipr(4) IP over raw HDLC ISDN driver. (optional)
    isdntxdel-outgoing
    A delay value suitable for the timeout(9) kernel subroutine to delay the transmission of the first packet after a successful connection is made by this value for outgoing 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 sense only) for the i4bipr(4) IP over raw HDLC ISDN driver. (optional)

    The local subaddress used when the local site dials out. When dialing out to a remote site, the subaddress specified here is put into the Calling Party Subaddress Information Element

    This keyword is mandatory for the ipr user-land interfaces.

    local-phone-incoming
    The local telephone number used for verifying the destination of incoming calls. When a remote site dials in, this number is used to verify that it is the local site which the remote site wants to connect to. It is compared with the Called Party Number Information Element got from the telephone exchange.

    This keyword is mandatory for the ipr interfaces.

    local-subaddr-incoming
    The local subaddress used for verifying the destination of incoming calls. When a remote site dials in, this subaddress is used to verify that it is the local site which the remote site wants to connect to. It is compared with the Called Party Subaddress Information Element got from the telephone exchange.

    Defines a symbolic name for this configuration entry. Its 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)
    maxconnecttime
    Specify a maximum connection time in seconds. Use this to define an absolute upper limit for a connection on the B-channel to last. CAUTION: This feature is used to limit the connection time, _not_ number of attempts to establish a connection: when using this please take care to also enable the use of budgets to limit the connection establish attempts (otherwise the line will cycle thru an endless loop of connections and reconnections which will have an undesired effect on your telco bill)!

    IDLETIME CALCULATION AND SHORT-HOLD MODE

    incoming calls
    It is assumed that the calling side knows most about charging structures and such and as a consequence only the keyword idletime-incoming has a function for incoming calls.

    For incoming calls the line is constantly monitored, and in case there was not traffic taking place for the time in seconds specified by idletime-incoming the call is closed.

    Typically, 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.

    outgoing calls
    Outgoing call disconnect time can be setup in one of three ways:

    simple mode
    For simple mode, the idle-algorithm-outgoing must be fix-unit-size and the selected unitlength must be 0 (zero) and idletime-outgoing greater zero.

    The outgoing traffic is constantly monitored, and in case there was not traffic taking place for the time in seconds specified by idletime-outgoing the call is closed.

    Typical values in simple mode are 10 to 30 seconds.

    shorthold mode for fixed unit charging
    For shorthold mode, the idle-algorithm-outgoing must be fix-unit-size and the selected unitlength and idletime-outgoing must be greater than 0 (zero); earlyhangup must be >= 0 (zero).
    |<unchecked-window>|<checkwindow>|<safetywindow>|
    |                  |             |              |
    +------------------+-------------+--------------+
    |                  |             |              |
    |                  |<-idle-time->|<earlyhangup->|
    |<--------------unitlength--------------------->|
    

    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.    #include <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.

    Notice: unitlength must (!) be greater than the sum of idletime-outgoing and earlyhangup

    shorthold mode for variable unit charging
    For shorthold mode, the idle-algorithm-outgoing must be var-unit-size and the selected unitlength and idletime-outgoing must be greater than 0 (zero);

    This shorthold mode is suitable when your calls are billed on the elapse time of the call plus a fixed connection charge. For example British Telecom bill this way.

    Each call is divided into two periods, the first is the unchecked period and the second is the checked The checked period starts 1 second before the first units time expires.

    During the checked period if there is no traffic for idle-time seconds the call is disconnected.

    |<---unchecked------------------>|<------checked------>
    +------------------+-------------+
    |                  |<-idle-time->|
    |<--------------unitlength------->|
    

    Experience shows that useful values for idle-time are from 15 to 30 seconds.

    If idle-time is too short an application that is not yet finished with the network will cause a new call to be placed.
