ISDN config: LBO values
Hi all,
When configuring Asterisk with an ISDN card, it will at one point
become necessary to select the LBO (Line Build-Out) value. This is an
integer (0-7) that is determined by the length of the cable and is
selected from the following table. Many of us are familiar with it:
CSU (dB) DSX-1 (feet)
