IAIK ISDN DIAL UP

IAIK - RAX ISDN Packetdriver Sample install

This work is sponsored by the Austrian National Bank.

The Test version of the CAPIPKT features the following command line parameters:

options :

  -?         ... help

  [-Pxx] -D  ... deinstall [pkt-drvr-interrupt]


  -Pxx       ... pkt_drvr_interrupt (default 60)

  -Ldddd     ... local ISDN-address (ignored for 2nd CAPIPKT)

  -Exxx      ... local EAZ-mask     (ignored for 2nd CAPIPKT)

  -Od        ... outgoing EAZ

  -Ndddd     ... dest. ISDN-address

  -Id.d.d.d  ... dest. IP-address

  -Sd.d.d.d  ... broadc.-subnet (default 255.255.255.255)

  -R         ... route bc-packets to dest.-address (ign. for 2nd CAPIPKT)

  -Axx       ... Common-ISDN-API-interrupt (default F1)


  -Cxx       ... CALL_BACK: call back xx times

  -C0        ... CALL_BACK: station is called_back

  -Kxx       ... RECALL: try xx times on conn-error

  -Tdd       ... ACTIVE_TIME: disconnect dd-seconds after last packet

  -Bdd       ... B-channels used by 1st CAPIPKT (ign. for 2nd CAPIPKT)

  dd .. decimal-number;  xx .. hex-number

A sample configuration defining two packet drivers could look like:

lh ..\edv\capipkt -l80191 -n481090 -i129.27.231.16 -s255.255.255.248 -p66 -t60


   ..\edv\load            -n481090 -i129.27.231.24 -s255.255.255.255 -p66 -t60

   ..\edv\capipkt -l80191 -n850680 -i129.27.231.25 -s255.255.255.255 -p65 -t60

   ..\edv\load            -n850140 -i129.27.231.32 -s255.255.255.255 -p65 -t20

ISDN frame format:

The alpha test version features the following frame format. You may contact us as to how to change this format.

-l3 :   1      2      6        6        2      n       2           1     Byte


       -------------------------------------------------------------------

       | flag | X.75 |Dst-Addr|Src-Addr| type | Data  | CRC-CCITT | flag |

       -------------------------------------------------------------------

This version is in permanent use in a ka9q based router with a primary rate interface. I has been successfully tested with various BRI products like DIEHL, AVM, TELES etc.

A documentation of the actual driver can be downloaded as RTF-file (1109K)
