So all frames in both directions -may be logged. -When the echo logging feature is used the number of available B-channels -for a HFC-PCI card is reduced to 1. Of course this is only relevant to -the card, not to the isdn line. -To activate the echo mode the following ioctls must be entered: - -hisaxctrl <driver/cardname> 10 1 - -This reduces the available channels to 1. There must not be open connections -through this card when entering the command. -And then: - -hisaxctrl <driver/cardname> 12 1 - -This enables the echo mode. If Hex logging is activated the isdnctrlx -devices show a output with a line beginning of HEX: for the providers -exchange and ECHO: for isdn devices sending to the provider. - -If more than one HFC-PCI cards are installed, a specific card may be selected -at the hisax module load command line. Supply the load command with the desired -IO-address of the desired card. -Example: -There tree cards installed in your machine at IO-base addresses 0xd000, 0xd400 -and 0xdc00 -If you want to use the card at 0xd400 standalone you should supply the insmod -or depmod with type=35 io=0xd400. -If you want to use all three cards, but the order needs to be at 0xdc00,0xd400, -0xd000 you may give the parameters type=35,35,35 io=0xdc00,0xd400,0xd00 -Then the desired card will be the initialised in the desired order. -If the io parameter is used the io addresses of all used cards should be -supplied else the parameter is assumed 0 and a auto search for a free card is -invoked which may not give the wanted result. - -Comments and reports to werner@isdn4linux.de or werner@isdn-development.de - - - |
