1 | The driver for the HFC-PCI and HFC-PCI-A chips from CCD may be used |
2 | for many OEM cards using this chips. | |
3 | Additionally the driver has a special feature which makes it possible | |
4 | to read the echo-channel of the isdn bus. So all frames in both directions | |
5 | may be logged. | |
6 | When the echo logging feature is used the number of available B-channels | |
7 | for a HFC-PCI card is reduced to 1. Of course this is only relevant to | |
8 | the card, not to the isdn line. | |
9 | To activate the echo mode the following ioctls must be entered: | |
10 | ||
11 | hisaxctrl <driver/cardname> 10 1 | |
12 | ||
13 | This reduces the available channels to 1. There must not be open connections | |
14 | through this card when entering the command. | |
15 | And then: | |
16 | ||
17 | hisaxctrl <driver/cardname> 12 1 | |
18 | ||
19 | This enables the echo mode. If Hex logging is activated the isdnctrlx | |
20 | devices show a output with a line beginning of HEX: for the providers | |
21 | exchange and ECHO: for isdn devices sending to the provider. | |
22 | ||
23 | If more than one HFC-PCI cards are installed, a specific card may be selected | |
24 | at the hisax module load command line. Supply the load command with the desired | |
25 | IO-address of the desired card. | |
26 | Example: | |
27 | There tree cards installed in your machine at IO-base addresses 0xd000, 0xd400 | |
28 | and 0xdc00 | |
29 | If you want to use the card at 0xd400 standalone you should supply the insmod | |
30 | or depmod with type=35 io=0xd400. | |
31 | If you want to use all three cards, but the order needs to be at 0xdc00,0xd400, | |
32 | 0xd000 you may give the parameters type=35,35,35 io=0xdc00,0xd400,0xd00 | |
33 | Then the desired card will be the initialised in the desired order. | |
34 | If the io parameter is used the io addresses of all used cards should be | |
35 | supplied else the parameter is assumed 0 and a auto search for a free card is | |
36 | invoked which may not give the wanted result. | |
