This mod is for ISDN based IPCops. With it, it is possible to connect or disconnect the second ISDN channel on the fly (multilink). Adding and removing the second channel is done via IPCop's dial screen and does not require an existing connection to be disconnected.

This mod is for IPCop v1.4.1, v1.4.2 and v1.4.4



IPCop's ISDN dialup settings 'single' and 'dual' will be changed to the following behavior:

• Configured as 'single', will only connect the first channel by default. The second channel can be added by selecting "Add ISDN-Channel" from the dial screen (or removed). If the connection is disconnected, it will always default to single channel, even if both channels were previously active.
  
  
• Configured as 'dual', will always connect both channels by default. The second channel can be removed by selecting "Remove ISDN-Channel" from the dial screen (or added). If the connection is disconnected, it will always default to dual channel, even if only one channel was previously active. (This is only valid if iBOD is not enabled, see notes below.)
  
  
• In both 'single' and 'dual' mode, the second channel can always be added or removed without affecting the first channel.
  
  
• Selecting "Add ISDN-Channel" or "Remove ISDN-Channel" from the dial screen, only takes effect if at least one channel is connected.
  

To use the manual add/remove channel features of this mod, you must disable IPCop's iBOD feature (Bandwidth on Demand for dual ISDN). iBOD will interfere with your manual channel selections if it is enabled.



Use this mod at your own risk. This mod has been tested with a simple ISDN setup. Make a backup of your IPCop's settings before you install. Be prepared to reinstall IPCop. If something goes wrong, your IPCop may lose the ability to connect. You have been warned.
