NAME

       isdnctrl - get/set ISDN device information


SYNOPSIS

       isdnctrl action device ...


DESCRIPTION

       isdnctrl  is used to create and delete network interfaces for ISDN, set
       up the various parameters and phone numbers for dial in and  dial  out.
       It is also used to list the current parameters of an already configured
       network interface.  isdnctrl is not needed for  configuration  of  ISDN
       ttys!

       The use of isdnctrl is independent of the hardware driver.



OPTIONS

       The following actions may be given to isdnctrl.

       addif name
              Adds  a  new ISDN interface name to the kernel. If name is omit-
              ted, the kernel will use ethX, where X is an  increasing  number
              starting  from 0. This is probably not useful with ISDN so using
              a name like isdn0 (for raw ip interfaces)  or  ippp0  (for  syn-
              chronous PPP interfaces) is always recommended.

       delif name [force]
              Removes the ISDN interface name from the kernel. If the optional
              keyword force is appended, isdnctrl executes ifconfig name  down
              before removing it.

       reset [force]
              Removes  all  ISDN interfaces from the kernel if it is possible.
              If the optional keyword force  is  appended,  isdnctrl  executes
              ifconfig name down before removing an interface.

       ifdefaults name
              resets the interface name to some reasonable defaults.

       dialmode name [off|manual|auto]
              Sets the dial mode of the interface to one of:

              off
              no  connection can be made; an existing connection is terminated
              immediately.  Incoming connections are also not possible.

              manual
              manual dialing / hangup; a connection will only  be  made  after
              isdnctrl  dial  name but the line will be disconnected after the
              huptimeout value set if using kernel drivers updated since 1 Nov
              1998;  otherwise an explicit isdnctrl hangup name will be needed
              to cause the connection to be dropped.
              Incoming connections are possible; however, if this interface is
              configured  in callback in mode, the callback dial will not hap-
              pen (as this is actually an outgoing connection, not an incoming
              one).

              auto
              autodial  mode; an outgoing packet will trigger a dialout, and a
              hangup will occur after  the  huptimeout  value  specified  (see
              below).
              An interface in auto dial mode will call another system back (if
              configured in callback in mode).

              auto was the "old" behaviour (as  it  was  before  dialmode  was
              implemented).

              If  no  argument  is  given,  the current dialmode value is dis-
              played.

              You can give all as the interface name; the command will then be
              executed for all interfaces.

       addphone name out num
              Adds the phone number num to the list of outgoing numbers of the
              ISDN interface name.  Numbers in this list are used to dial  the
              remote  station  if the connection is down and packets are to be
              sent via the interface (Dial on demand). More  than  one  number
              can be set by calling isdnctrl addphone repeatedly. If more than
              one number is set, these will be tried one  after  another  (the
              last  added  number  is tried first, etc.).  When using a german
              SPV-type connection, the number has to be prefixed by a  capital
              S.

       addphone name in num
              Adds the phone number num to the list of incoming numbers of the
              ISDN interface name.  Numbers in this list are  used  to  verify
              access  permission  of the remote station if an incoming call is
              received. The verification can be disabled by setting the inter-
              face  into insecure mode using isdnctrl name secure off.  If the
              list is empty, incoming calls are disabled.  More than one  num-
              ber  can  be added by calling isdnctrl addphone repeatedly. Also
              wildcards can be used (see below).

       delphone name in|out num
              Removes phone number num from the  incoming  or  outgoing  phone
              list.

       eaz name [num]
              Set the EAZ (German 1TR6 protocol) or MSN (Euro-ISDN E-DSS1) for
              ISDN interface name to num.  For an EAZ this is only one  digit,
              while  for  an MSN num is the whole MSN (usually the local phone
              number). If num is omitted, isdnctrl prints the current  setting
              for ISDN interface name.

       huptimeout name [seconds]
              Set  the  hangup timeout for ISDN interface name to seconds.  If
              there is inactivity (i.e. no traffic on the interface)  for  the
              given  time  the driver automatically shuts down the connection.
              If seconds is omitted isdnctrl prints the  current  setting  for
              interface name.

       cbdelay name [seconds]
              Set  the  callback delay for ISDN interface name to seconds.  If
              callback mode for this interface is in, dialing is  delayed  the
              given  time.  If the callback mode is out, after dialing out and
              waiting the given time, a hangup is issued to free the line  for
              the  incoming  callback  from  the  remote machine. This hangup-
              after-dial is disabled by setting cbdelay to 0.  If  seconds  is
              omitted  isdnctrl prints the current setting for interface name.

       dialmax name [num]
              Set the number of dial attempts for ISDN interface name to  num.
              If  dialing,  each  phone number is tried this many times before
              giving up.  If num is omitted isdnctrl prints the  current  set-
              ting for interface name.

       ihup name [on|off]
              Turn  on  or off the hangup timeout for incoming calls on inter-
              face name.  If on or off  is  omitted  the  current  setting  is
              printed.

       chargehup name [on|off]
              Turn  on  or  off  hangup  before next charge info for interface
              name.  This can only be used  if  the  ISDN  provider  transmits
              charge  info during and after the connection.  If set to on, the
              driver will close the connection just  before  the  next  charge
              info will be received if the interface is inactive. If on or off
              is omitted the current setting is printed.

       chargeint name [seconds]
              If seconds are given, the charge interval for the  given  inter-
              face is set. This may be useful on ISDN lines with no chargeinfo
              or no online chargeinfo. The connection will be closed 2 seconds
              before the end of the next estimated charge interval if huptime-
              out seconds of inactivity have been  reached.  If  ihup  is  on,
              incoming  connections  are  closed  by  this mechanism also.  On
              lines with online charge info you also might  ask  by  chargeint
              name for the current charge interval as delivered from the tele-
              com on a given interface.

       secure name [on|off]
              Turns on or off the security feature for interface name.  If set
              to  on, incoming calls will only be accepted if the calling num-
              ber can be found in the incoming access list. See description of
              action addphone for information about how to add numbers to this
              list.  If on or off is omitted, the current setting is  printed.

       callback name [mode]
              Set  callback mode for interface name to mode mode.  If callback
              mode is in, then after getting an incoming call, a  callback  is
              triggered.  If  callback mode is out, then the local system does
              the initial call and then  waits  for  callback  of  the  remote
              machine.  The option on is available only for compatibility with
              older versions. Its meaning is the same like  in.   If  callback
              mode is off, calls are handled normally without special process-
              ing.

       cbhup name [on|off]
              Turns on or off Hangup (Reject) for interface name before start-
              ing  callback.  If cbhup is on, when receiving an incoming call,
              the interface  first  rejects  that  call  before  the  callback
              sequence  is  started. If on or off is omitted, the current set-
              ting is printed.

       encap name [encapsulation]
              Set the encapsulation mode for interface name.  Possible  encap-
              sulations are:

              rawip
              raw ip encapsulation (default)

              ip
              IP + typefield encapsulation

              cisco-h
              Special  mode  for  communicating with a Cisco in HDLC-mode with
              Cisco-keepalive switched off.

              ethernet
              ethernet over ISDN (MAC-header included)

              syncppp
              Synchronous PPP over ISDN

              uihdlc
              raw ip with additional ui-header

              cisco-hk
              Special mode for communicating with a Cisco  in  HDLC-mode  with
              Cisco-keepalive switched on.

              x25iface
              Provides an interface as required by the Linux X.25 PLP protocol
              implementation (requires Linux 2.1.x or newer).

       If encapsulation is omitted, the current setting is printed.

       l2_prot name [protocol]
              Set the layer-2 protocol for interface  name.   Possible  values
              for protocol are:
              x75i,  x75ui,  x75bui and hdlc.  If protocol is omitted the cur-
              rent setting is printed.

       l3_prot  name  [ protocol ]
              Set the layer-3 protocol for interface name.  At the moment only
              trans  is  supported  here.   If protocol is omitted the current
              setting is printed.

       list name
              List all parameters and the charge info for interface name.   If
              name is all, then all interfaces are listed.

       status name
              Show  the  connection status for interface name.  The output can
              be one of the following types:

              ippp0 not connected
              There is no connection

              ippp0 connected to 0123456789
              There is an outgoing connection to phone number 0123456789

              ippp0 connected from 0123456789
              There is an incoming connection from phone number 0123456789

       If the interface is connected, the exit status of the command is  true,
       else it is false.
       If name is all, then the connection status for all interfaces is shown.
       The exit status is always true in this case.
       If name is active, then only those interfaces that are  currently  con-
       nected are shown. The exit status is always true in this case.

       verbose num
              Set verbosity level to num.

       hangup name
              The connection of interface name is closed immediately.

       bind name driverId,channel [exclusive]
              Binds  an  interface  name  to a physical channel.  The driverId
              identifies a specific S0-Port. The  channels  of  a  port  start
              counting with zero. If exclusive is given, other interfaces can-
              not use that channel anymore.  Otherwise,  the  channel  may  be
              used by other interfaces.

       unbind name
              Unbinds a the previously bound interface name.

       pppbind name [num]
              Binds  the  interface name to an ippp device /dev/ipppnum.  This
              works only for synchronous ppp. The value must be a number.   If
              num  is omitted and name is called ipppX , then the interface is
              bound to /dev/ipppX.

       pppunbind name
              Unbinds the previously bound interface name.


       busreject driverId [on|off]
              If switched on, instead of ignoring incoming calls not  matching
              any interface, isdn4linux responds with a REJECT to those calls.
              If switched off, isdn4linux is passive, allowing  other  devices
              connected  to  the same S0-bus to answer the call.  You normally
              should not enable this feature, if the ISDN adaptor is  not  the
              only device connected to the S0-bus.  Otherwise it could happen,
              that isdn4linux  rejects  an  incoming  call  which  belongs  to
              another device on the bus.


       addslave name slave
              Adds  a  slave  interface  named slave to interface name for raw
              channel-bundling. For bundling of more than  two  channels,  any
              number of slaves can be added to an interface by using this com-
              mand repeatedly.  name must refer to an existing "master" inter-
              face (not a slave). Slave interfaces are not visible to the ker-
              nel, however all usual ISDN settings can be configured.  Because
              slave interfaces are not visible to the kernel, they are config-
              ured "through" their "master", so it  is  important  that  slave
              interfaces  are  added  before  the  corresponding  "master"  is
              started by ifconfig.  If the "master" is already up, it  has  to
              be  shutdown with ifconfig down ...  otherwise the addslave com-
              mand will be rejected.


       sdelay name num
              Set delay for slave-dialing.  The master interface name  has  to
              have  a  load of more than trigger cps for at least num seconds,
              before its slave starts dialing.
              Note that this only works for rawIP, not MPPP!


       trigger name num
              Set trigger level for slave-dialing.  The master interface  name
              has to have a load of more than num cps for at least sdelay sec-
              onds, before its slave starts dialing.
              Note that this only works for rawIP, not MPPP!


       addlink name
              For MPPP, this adds a slave interface to  the  existing  connec-
              tion, i.e. connect the extra channel now. It is like a dial com-
              mand for the extra channel.
              This also means that addlink will only work if the master inter-
              face  name must already be connected! Also, the dialmode for the
              slave interface must be auto.


       removelink name
              For MPPP, this removes a slave interface from the existing  con-
              nection, i.e. hangup the extra channel now.


       dial name
              Force dialing of interface name.

       mapping driverId MSN0[,MSN1[,MSN2]] ... [,MSN9]
              Installs  a  mapping-table for MSN<->EAZ-mapping. See README for
