Chapter 3: Configuration
Configuring T1/E1 Lines
1.
Begin by opening the system.conf file from the
/etc/dahdi
directory.
2.
Specify the two letter country code for your loadzone and defaultzone.
This will preload tone zone data and specify a default tone zone for
your interfaces.
The following is a typical setup for a telco in the US:
loadzone = us
defaultzone = us
3.
Configure the SPAN Map.
You will need to define a span. The SPAN map includes defining the
SPAN number, timing, line build out, framing, and coding.
Configuration details for each of these items is explained in this
section.
span => <Number>,<Timing>,<Line Build
Out>,<Framing>,<Coding>[,Yellow]
Number:
This is the port the T1/E1 is plugged into. The TE120 Series cards
only have one port. If you have a single TE120 Series card installed in
the system, you should specify 1 as the span number.
