1.
Begin by
opening the
system.conf
file from the
/etc/dahdi
directory.
2.

loadzone = us
defaultzone = us

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 line is plugged into. Port 1 being the furthest
span from the PCI bus. The port numbers are noted on the PCI bracket.
