18 | * module parameters: | |
19 | * type: | |
20 | * By default (0), the card is automatically detected. | |
21 | * Or use the following combinations: | |
22 | * Bit 0-7 = 0x00001 = HFC-E1 (1 port) | |
23 | * or Bit 0-7 = 0x00004 = HFC-4S (4 ports) | |
24 | * or Bit 0-7 = 0x00008 = HFC-8S (8 ports) | |
25 | * Bit 8 = 0x00100 = uLaw (instead of aLaw) | |
26 | * Bit 9 = 0x00200 = Disable DTMF detect on all B-channels via hardware | |
27 | * Bit 10 = spare | |
28 | * Bit 11 = 0x00800 = Force PCM bus into slave mode. (otherwhise auto) | |
29 | * or Bit 12 = 0x01000 = Force PCM bus into master mode. (otherwhise auto) | |
30 | * Bit 13 = spare | |
31 | * Bit 14 = 0x04000 = Use external ram (128K) | |
32 | * Bit 15 = 0x08000 = Use external ram (512K) | |
33 | * Bit 16 = 0x10000 = Use 64 timeslots instead of 32 | |
34 | * or Bit 17 = 0x20000 = Use 128 timeslots instead of anything else | |
35 | * Bit 18 = spare | |
36 | * Bit 19 = 0x80000 = Send the Watchdog a Signal (Dual E1 with Watchdog) | |
37 | * (all other bits are reserved and shall be 0) | |
38 | * example: 0x20204 one HFC-4S with dtmf detection and 128 timeslots on PCM | |
39 | * bus (PCM master) | |
40 | * | |
41 | * port: (optional or required for all ports on all installed cards) | |
42 | * HFC-4S/HFC-8S only bits: | |
43 | * Bit 0 = 0x001 = Use master clock for this S/T interface | |
44 | * (ony once per chip). | |
45 | * Bit 1 = 0x002 = transmitter line setup (non capacitive mode) | |
46 | * Don't use this unless you know what you are doing! | |
47 | * Bit 2 = 0x004 = Disable E-channel. (No E-channel processing) | |
48 | * example: 0x0001,0x0000,0x0000,0x0000 one HFC-4S with master clock | |
49 | * received from port 1 | |
50 | * | |
51 | * HFC-E1 only bits: | |
52 | * Bit 0 = 0x0001 = interface: 0=copper, 1=optical | |
53 | * Bit 1 = 0x0002 = reserved (later for 32 B-channels transparent mode) | |
54 | * Bit 2 = 0x0004 = Report LOS | |
55 | * Bit 3 = 0x0008 = Report AIS | |
56 | * Bit 4 = 0x0010 = Report SLIP | |
57 | * Bit 5 = 0x0020 = Report RDI | |
58 | * Bit 8 = 0x0100 = Turn off CRC-4 Multiframe Mode, use double frame | |
59 | * mode instead. | |
60 | * Bit 9 = 0x0200 = Force get clock from interface, even in NT mode. | |
61 | * or Bit 10 = 0x0400 = Force put clock to interface, even in TE mode. | |
62 | * Bit 11 = 0x0800 = Use direct RX clock for PCM sync rather than PLL. | |
63 | * (E1 only) | |
64 | * Bit 12-13 = 0xX000 = elastic jitter buffer (1-3), Set both bits to 0 | |
65 | * for default. | |
66 | * (all other bits are reserved and shall be 0) | |
67 | * | |
68 | * debug: | |
69 | * NOTE: only one debug value must be given for all cards | |
70 | * enable debugging (see hfc_multi.h for debug options) | |
71 | * | |
72 | * poll: | |
73 | * NOTE: only one poll value must be given for all cards | |
74 | * Give the number of samples for each fifo process. | |
75 | * By default 128 is used. Decrease to reduce delay, increase to | |
76 | * reduce cpu load. If unsure, don't mess with it! | |
77 | * Valid is 8, 16, 32, 64, 128, 256. | |
78 | * | |
79 | * pcm: | |
80 | * NOTE: only one pcm value must be given for every card. | |
81 | * The PCM bus id tells the mISDNdsp module about the connected PCM bus. | |
82 | * By default (0), the PCM bus id is 100 for the card that is PCM master. | |
83 | * If multiple cards are PCM master (because they are not interconnected), | |
84 | * each card with PCM master will have increasing PCM id. | |
85 | * All PCM busses with the same ID are expected to be connected and have | |
86 | * common time slots slots. | |
87 | * Only one chip of the PCM bus must be master, the others slave. | |
88 | * -1 means no support of PCM bus not even. | |
89 | * Omit this value, if all cards are interconnected or none is connected. | |
90 | * If unsure, don't give this parameter. | |
91 | * | |
07003408 AE |
92 | * dmask and bmask: |
93 | * NOTE: One dmask value must be given for every HFC-E1 card. | |
94 | * If omitted, the E1 card has D-channel on time slot 16, which is default. | |
95 | * dmask is a 32 bit mask. The bit must be set for an alternate time slot. | |
96 | * If multiple bits are set, multiple virtual card fragments are created. | |
97 | * For each bit set, a bmask value must be given. Each bit on the bmask | |
98 | * value stands for a B-channel. The bmask may not overlap with dmask or | |
99 | * with other bmask values for that card. | |
100 | * Example: dmask=0x00020002 bmask=0x0000fffc,0xfffc0000 | |
101 | * This will create one fragment with D-channel on slot 1 with | |
102 | * B-channels on slots 2..15, and a second fragment with D-channel | |
103 | * on slot 17 with B-channels on slot 18..31. Slot 16 is unused. | |
104 | * If bit 0 is set (dmask=0x00000001) the D-channel is on slot 0 and will | |
105 | * not function. | |
106 | * Example: dmask=0x00000001 bmask=0xfffffffe | |
107 | * This will create a port with all 31 usable timeslots as | |
108 | * B-channels. | |
109 | * If no bits are set on bmask, no B-channel is created for that fragment. | |
110 | * Example: dmask=0xfffffffe bmask=0,0,0,0.... (31 0-values for bmask) | |
111 | * This will create 31 ports with one D-channel only. | |

112 | * If you don't know how to use it, you don't need it! |
113 | * | |
114 | * iomode: | |
115 | * NOTE: only one mode value must be given for every card. | |
116 | * -> See hfc_multi.h for HFC_IO_MODE_* values | |
117 | * By default, the IO mode is pci memory IO (MEMIO). | |
f77f13e2 | 118 | * Some cards require specific IO mode, so it cannot be changed. |
25985edc | 119 | * It may be useful to set IO mode to register io (REGIO) to solve |
af69fb3a KK |
120 | * PCI bridge problems. |
121 | * If unsure, don't give this parameter. | |
122 | * | |
123 | * clockdelay_nt: | |
124 | * NOTE: only one clockdelay_nt value must be given once for all cards. | |
125 | * Give the value of the clock control register (A_ST_CLK_DLY) | |
126 | * of the S/T interfaces in NT mode. | |
127 | * This register is needed for the TBR3 certification, so don't change it. | |
128 | * | |
129 | * clockdelay_te: | |
130 | * NOTE: only one clockdelay_te value must be given once | |
131 | * Give the value of the clock control register (A_ST_CLK_DLY) | |
132 | * of the S/T interfaces in TE mode. | |
133 | * This register is needed for the TBR3 certification, so don't change it. | |
3bd69ad1 AE |
134 | * |
135 | * clock: | |
1b36c78f | 136 | * NOTE: only one clock value must be given once |
3bd69ad1 AE |
137 | * Selects interface with clock source for mISDN and applications. |
138 | * Set to card number starting with 1. Set to -1 to disable. | |
139 | * By default, the first card is used as clock source. | |
db9bb63a KK |
140 | * |
141 | * hwid: | |
142 | * NOTE: only one hwid value must be given once | |
475be4d8 | 143 | * Enable special embedded devices with XHFC controllers. |
