See the 13 GNU General Public License for more details. 14 15 However, if you wish to modify the HiSax sources, please note the following: 16 17 HiSax has passed the ITU approval test suite with ELSA Quickstep ISDN cards 18 and Eicon Technology Diva 2.01 PCI card. 19 The certification is only valid for the combination of the tested software 20 version and the tested hardware. Any changes to the HiSax source code may 21 therefore affect the certification. 22 23 Additional ITU approval tests have been carried out for all generic cards 24 using Colognechip single chip solutions HFC-S PCI A for PCI cards as well 25 as HFC-S USB based USB ISDN ta adapters. 26 These tests included all layers 1-3 and as well all functional tests for 27 the layer 1. Because all hardware based on these chips are complete ISDN 28 solutions in one chip all cards and USB-TAs using these chips are to be 29 regarded as approved for those tests. Some additional electrical tests 30 of the layer 1 which are independent of the driver and related to a 31 special hardware used will be regarded as approved if at least one 32 solution has been tested including those electrical tests. So if cards 33 or tas have been completely approved for any other os, the approval 34 for those electrical tests is valid for linux, too. 35 Please send any questions regarding this drivers or approval abouts to 36 werner@isdn-development.de 37 Additional information and the type approval documents will be found 38 shortly on the Colognechip website www.colognechip.com 39 40 If you change the main files of the HiSax ISDN stack, the certification will 41 become invalid. Because in most countries it is illegal to connect 42 unapproved ISDN equipment to the public network, I have to guarantee that 43 changes in HiSax do not affect the certification. 44 45 In order to make a valid certification apparent to the user, I have built in 46 some validation checks that are made during the make process. The HiSax main 47 files are protected by md5 checksums and the md5sum file is pgp signed by 48 myself: 49 50 KeyID 1024/FF992F6D 1997/01/16 Karsten Keil <kkeil@suse.de> 51 Key fingerprint = 92 6B F7 58 EE 86 28 C8 C4 1A E6 DC 39 89 F2 AA 52 53 Only if the checksums are OK, and the signature of the file 54 "drivers/isdn/hisax/md5sums.asc" match, is the certification valid; a 55 message confirming this is then displayed during the hisax init process. 56 57 The affected files are: 58 59 drivers/isdn/hisax/isac.c 60 drivers/isdn/hisax/isdnl1.c 61 drivers/isdn/hisax/isdnl2.c 62 drivers/isdn/hisax/isdnl3.c 63 drivers/isdn/hisax/tei.c 64 drivers/isdn/hisax/callc.c 65 drivers/isdn/hisax/l3dss1.c 66 drivers/isdn/hisax/l3_1tr6.c 67 drivers/isdn/hisax/cert.c 68 drivers/isdn/hisax/elsa.c 69 drivers/isdn/hisax/diva.c 70 drivers/isdn/hisax/hfc_pci.c 71 72 Please send any changes, bugfixes and patches to me rather than implementing 73 them directly into the HiSax sources. 74 75 This does not reduce your rights granted by the GNU General Public License. 76 If you wish to change the sources, go ahead; but note that then the 77 certification is invalid even if you use one of the approved cards. 78 79 Here are the certification registration numbers for ELSA Quickstep cards: 80 German D133361J CETECOM ICT Services GmbH 0682 81 European D133362J CETECOM ICT Services GmbH 0682 82 83 84 Karsten Keil 85 keil@isdn4linux.de 86 87 -----BEGIN PGP SIGNATURE----- 88 Version: 2.6.3i 89 Charset: noconv 90 91 iQCVAwUBOFAwqTpxHvX/mS9tAQFI2QP9GLDK2iy/KBhwReE3F7LeO+tVhffTVZ3a 92 20q5/z/WcIg/pnH0uTkl2UgDXBFXYl45zJyDGNpAposIFmT+Edd14o7Vj1w/BBdn 93 Y+5rBmJf+gyBu61da5d6bv0lpymwRa/um+ri+ilYnZ/XPfg5JKhdjGSBCJuJAElM 94 d2jFbTrsMYw= 95 =LNf9 96 -----END PGP SIGNATURE-----
