28 * Thanks to Cologne Chip AG for this great controller!
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
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)
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
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
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
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
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.
78 * Bit 12-13 = 0xX000 = elastic jitter buffer (1-3), Set both bits to 0
80 * (all other bits are reserved and shall be 0)
83 * NOTE: only one debug value must be given for all cards
84 * enable debugging (see hfc_multi.h for debug options)
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.
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.
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!
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.
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.
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.
139 * debug register access (never use this, it will flood your system log)
