Asterisk 安装笔记 E1 on Dahdi 的配置

安装好 dahdi之后，make config就会生成默认的配置文件

/etc/dahdi/init.conf

init.d自动启动脚本的配置，一般不需要改，以前是放在/etc/sysconfig下面的

/etc/dahdi/modules

需要加载的modules，看你的板卡型号，把不需要的注释掉

我的是TE410P，使用 wct4xxp

# Digium TE205P/TE207P/TE210P/TE212P: PCI dual-port T1/E1/J1
# Digium TE405P/TE407P/TE410P/TE412P: PCI quad-port T1/E1/J1
# Digium TE220: PCI-Express dual-port T1/E1/J1
# Digium TE420: PCI-Express quad-port T1/E1/J1
wct4xxp

/etc/dahdi/system.conf

最重要的配置文件，里面参数很多，基本都有注释，很清楚的了。

下面是我的情况，一条E1连接到该卡#1端口上面，配置如下

# Span 1: TE4/0/1 “T4XXP (PCI) Card 0 Span 1″ (MASTER) HDB3/CCS
span=1,1,0,ccs,hdb3
# termtype: te
bchan=1-15,17-31
dchan=16
echocanceller=mg2,1-15,17-31

# Global data

loadzone = no
defaultzone = no

请参照你的E1，看看有没有用crc4，我配置了半天发现我的E1上面是不能加crc4的，郁闷死，嘿嘿。defaultzone 据说中国设置为no。

另外echocanceller也很重要，这个是硬件的回音消除，TE410P就支持。

/etc/modprobe.d/blacklist

这个是modules 不加载的列表，默认是要先取消所有模块，然后再加载。不用改

/etc/modprobe.d/dahdi

这个是每个模块的特别设置，比如T1到E1的软跳线，4个端口，一个个跳

The driver accepts parameter t1e1override and decimal value between 0 and 15 wich corespond to binary from 0000 to 1111 where each bit corespond to a span. 0 is T1 and 1 is E1.

< |>      0       |   0000
      1       |   0001
      2       |   0010
      3       |   0011
      4       |   0100
      5       |   0101
      6       |   0110
      7       |   0111
      8       |   1000
      9       |   1001
      10     |   1010
      11     |   1011
      12     |   1100
      13     |   1101
      14     |   1110
      15     |   1111

But how to know which port is configured for T1 or E1? Take a look at the picture below.

Spans 4 3 2 1

debug就是调试信息输出到syslog

noburst 就是是否开启突发传输，默认noburst=1就是关闭burst

options wct4xxp t1e1override=15 debug=1 noburst=0
options dahdi debug=1

启动脚本：

/etc/init.d/dahdi

Asterisk 1.6的配置文件：chan_dahdi.conf

[channels]
language=en
context=default

switchtype=euroisdn
pridialplan=national

internationalprefix = +
nationalprefix = +86
localprefix = +8620
