6 dahdi_span_types - set line modes of DAHDI spans before assignment
7
9 dahdi_span_types [options] <list|dumpconfig|set> [devpath ...]
10
13 The span type (the line mode: E1/T1/J1) must be set to a span before
14 DAHDI assigns it a span number, as E1 spans use more channels.
15 dahdi_span_types applies the span type configuration to an un-assigned
16 span.
17 Using it only makes sense when the kernel module parameter
19 dahdi.auto_assign_span is unset, otherwise DAHDI automatically assign
20 span numbers during device registration.
21 dahdi_span_types takes a command and an optional list of devices. If no
23 device is given, the command is applied to all devices.
24 The device is marked as a path in the SysFS tree.
26
29 -h|--help
30 Output usage message and exit
31 -n|--dry-run
33 During "set" operation, only show what would be done, without
34 actually changing anything.
35 -v|--verbose
37 During "set" operation, show the actions that are being per‐
38 formed.
39 --line-mode=<E1|T1|J1>
41 During "dumpconfig" operation, force special generation mode:
42 · First, generates a "wildcard" entry with the fiven line-mode.
44 · Comment out all span entries. Each of them may be manually
46 un-commented to override the "wildcard".
47
50 set
51 Reads settings from span-types.conf and applies them to the
52 device(s) specified in the command line (or all devices, if none
53 specified).
54 list
56 List line modes for all spans in the system which may be set
57 with dahdi_span_types (E1/T1/J1 spans).
58 dumpconfig
60 List types for the spans in a format fit to be used in
61 span-types.conf. Use this to generate a configuration file after
62 you have (perhaps manually) set all existing spans.
63 dahdi_genconf spantypes uses this command internally.
65
68 General structure
69 span-types.conf is a file with lines specifying line modes of spans.
70 Empty lines or lines beginning with '#' are ignored.
72 Each line is in the format of:
74 ID spanspec ...
76 The ID field specifies the DAHDI device and the spanspecs define the
78 line modes of its spans. A line may have multiple spanspecs in a single
79 line (though dumpconfig generates a configuration with one per line).
80 Span Identifier
83 A DAHDI device may be specified either by a hardware identifier (a
84 software readable serial number or whatever) or the location in which
85 it is installed on the system. The former makes it simpler to change
86 connector / slot whereas the latter makes it simpler to replace a unit.
87 The value in this field is matched (when the command set is used) to
89 the following values:
90 hwid
92 @location
93 devpath
94 See above for their descriptions. The value may include shell wild‐
96 cards: *, ? and [], which are used in the match. The values to be
97 matched are first cleaned up: '!' is replaced with '/' and any charac‐
98 ter not in "a-zA-Z0-9/:.-" is replaced by "_".
99 Note that while span-types.conf allows an arbitrarily-complex combina‐
101 tion of E1, J1 and T1 ports, it would normally have just a single wild‐
102 card line setting the line mode (the first line in the example below).
103 Span Specification
106 Each line should have one or more span specifications: this is the
107 value used to set span type with DAHDI in the SysFS interface. A speci‐
108 fication has two colon-separated fields:
109 rel_span_no:span_type
111 for instance, the following are four span specifications specify ports
113 1 and 2 as E1 and ports 3 and 4 as T1: [12]:E1 [34]:T1 .
114 rel_span_no
116 The relative number of the span in the device. E.g.: port num‐
117 ber. This field may contain shell wildcards (*, ? and [])
118 span_type
120 E1/T1/J1
121 Multiple matches
124 During set operation, the dahdi_span_types applies all matching set‐
125 tings to a span. This is done in the order of lines in the configura‐
126 tion files.
127 Thus, if there are multiple matches to a span -- the last match will
129 win (all will be applied to the kernel in order. The last one in the
130 file will be applied last).
131 Example:
133 * *:T1 # All spans on all devices will be T1
134 usb:X1234567 [34]:E1 # Except spans 3,4 on the device which will be E1
135
139 DAHDICONFDIR
140 The directory in which span-types.conf resides. /etc/dahdi if
141 not overridden from the environment.
142 DAHDISPANTYPESCONF
144 The path to span-types.conf resides. /etc/dahdi/span-types.conf
145 if not overridden from the environment.
146
150 /etc/dahdi/span-types.conf
151 The default location for the configuration file.
152 /sys/bus/dahdi_devices/devices/device
154 SysFS node for the device. In this directory reside the follow‐
155 ing files, among others:
156 spantype
158 read/write file. Reading from it returns current configu‐
159 ration for spans of the device. Span-specifications can
160 be written to it to change line modes (but only for a
161 span that is not assigned yet).
