32 | * module parameters: | |
33 | * type: | |
34 | * By default (0), the card is automatically detected. | |
35 | * Or use the following combinations: | |
36 | * Bit 0-7 = 0x00001 = HFC-E1 (1 port) | |
37 | * or Bit 0-7 = 0x00004 = HFC-4S (4 ports) | |
38 | * or Bit 0-7 = 0x00008 = HFC-8S (8 ports) | |
39 | * Bit 8 = 0x00100 = uLaw (instead of aLaw) | |
40 | * Bit 9 = 0x00200 = Disable DTMF detect on all B-channels via hardware | |
41 | * Bit 10 = spare | |
42 | * Bit 11 = 0x00800 = Force PCM bus into slave mode. (otherwhise auto) | |
43 | * or Bit 12 = 0x01000 = Force PCM bus into master mode. (otherwhise auto) | |
44 | * Bit 13 = spare | |
45 | * Bit 14 = 0x04000 = Use external ram (128K) | |
46 | * Bit 15 = 0x08000 = Use external ram (512K) | |
47 | * Bit 16 = 0x10000 = Use 64 timeslots instead of 32 | |
48 | * or Bit 17 = 0x20000 = Use 128 timeslots instead of anything else | |
49 | * Bit 18 = spare | |
50 | * Bit 19 = 0x80000 = Send the Watchdog a Signal (Dual E1 with Watchdog) | |
51 | * (all other bits are reserved and shall be 0) | |
52 | * example: 0x20204 one HFC-4S with dtmf detection and 128 timeslots on PCM | |
53 | * bus (PCM master) | |
54 | * | |
55 | * port: (optional or required for all ports on all installed cards) | |
56 | * HFC-4S/HFC-8S only bits: | |
57 | * Bit 0 = 0x001 = Use master clock for this S/T interface | |
58 | * (ony once per chip). | |
59 | * Bit 1 = 0x002 = transmitter line setup (non capacitive mode) | |
60 | * Don't use this unless you know what you are doing! | |
61 | * Bit 2 = 0x004 = Disable E-channel. (No E-channel processing) | |
62 | * example: 0x0001,0x0000,0x0000,0x0000 one HFC-4S with master clock | |
63 | * received from port 1 | |
64 | * | |
65 | * HFC-E1 only bits: | |
66 | * Bit 0 = 0x0001 = interface: 0=copper, 1=optical | |
67 | * Bit 1 = 0x0002 = reserved (later for 32 B-channels transparent mode) | |
68 | * Bit 2 = 0x0004 = Report LOS | |
69 | * Bit 3 = 0x0008 = Report AIS | |
70 | * Bit 4 = 0x0010 = Report SLIP | |
71 | * Bit 5 = 0x0020 = Report RDI | |
72 | * Bit 8 = 0x0100 = Turn off CRC-4 Multiframe Mode, use double frame | |
73 | * mode instead. | |
74 | * Bit 9 = 0x0200 = Force get clock from interface, even in NT mode. | |
75 | * or Bit 10 = 0x0400 = Force put clock to interface, even in TE mode. | |
76 | * Bit 11 = 0x0800 = Use direct RX clock for PCM sync rather than PLL. | |
77 | * (E1 only) | |
78 | * Bit 12-13 = 0xX000 = elastic jitter buffer (1-3), Set both bits to 0 | |
79 | * for default. | |
80 | * (all other bits are reserved and shall be 0) | |
81 | * | |
82 | * debug: | |
83 | * NOTE: only one debug value must be given for all cards | |
84 | * enable debugging (see hfc_multi.h for debug options) | |
85 | * | |
86 | * poll: | |
87 | * NOTE: only one poll value must be given for all cards | |
88 | * Give the number of samples for each fifo process. | |
89 | * By default 128 is used. Decrease to reduce delay, increase to | |
90 | * reduce cpu load. If unsure, don't mess with it! | |
91 | * Valid is 8, 16, 32, 64, 128, 256. | |
92 | * | |
93 | * pcm: | |
94 | * NOTE: only one pcm value must be given for every card. | |
95 | * The PCM bus id tells the mISDNdsp module about the connected PCM bus. | |
96 | * By default (0), the PCM bus id is 100 for the card that is PCM master. | |
97 | * If multiple cards are PCM master (because they are not interconnected), | |
98 | * each card with PCM master will have increasing PCM id. | |
99 | * All PCM busses with the same ID are expected to be connected and have | |
100 | * common time slots slots. | |
101 | * Only one chip of the PCM bus must be master, the others slave. | |
102 | * -1 means no support of PCM bus not even. | |
103 | * Omit this value, if all cards are interconnected or none is connected. | |
104 | * If unsure, don't give this parameter. | |
105 | * | |
106 | * dslot: | |
107 | * NOTE: only one poll value must be given for every card. | |
108 | * Also this value must be given for non-E1 cards. If omitted, the E1 | |
109 | * card has D-channel on time slot 16, which is default. | |
110 | * If 1..15 or 17..31, an alternate time slot is used for D-channel. | |
111 | * In this case, the application must be able to handle this. | |
112 | * If -1 is given, the D-channel is disabled and all 31 slots can be used | |
113 | * for B-channel. (only for specific applications) | |
114 | * If you don't know how to use it, you don't need it! | |
115 | * | |
116 | * iomode: | |
117 | * NOTE: only one mode value must be given for every card. | |
118 | * -> See hfc_multi.h for HFC_IO_MODE_* values | |
119 | * By default, the IO mode is pci memory IO (MEMIO). | |
120 | * Some cards requre specific IO mode, so it cannot be changed. | |
121 | * It may be usefull to set IO mode to register io (REGIO) to solve | |
122 | * PCI bridge problems. | |
123 | * If unsure, don't give this parameter. | |
124 | * | |
125 | * clockdelay_nt: | |
126 | * NOTE: only one clockdelay_nt value must be given once for all cards. | |
127 | * Give the value of the clock control register (A_ST_CLK_DLY) | |
128 | * of the S/T interfaces in NT mode. | |
129 | * This register is needed for the TBR3 certification, so don't change it. | |
130 | * | |
131 | * clockdelay_te: | |
132 | * NOTE: only one clockdelay_te value must be given once | |
133 | * Give the value of the clock control register (A_ST_CLK_DLY) | |
134 | * of the S/T interfaces in TE mode. | |
135 | * This register is needed for the TBR3 certification, so don't change it. | |
