Maybe I need to be a little more specific.
I know what signal attenuation is. What I don't know, is how LBO (and
specifically the implementation of it as used in the zaptel hardware/software)
helps the situation.
My servers are co-located with my carrier, and my PRI circuits are run through
several patch panels, jumpers, etc. to another room, where they terminate on a
DMS-100. I have asked the carrier for an estimated cable length, so i can
correctly set the LBO.
In the zaptel config, what is meant by DSX-1? What is CSU?
Why would I use a -7.5db, -15db or -22.5db LBO?

Subject: [Asterisk-Users] Zaptel Line Build Out
Can someone who is knowledgable in the traditional telco space please give
me a
layman's explanation (or point me to an appropriate url) of LBO as per the
zaptel configuration file?
# The line build-out (or LBO) is an integer, from the following table:
# 0: 0 db (CSU) / 0-133 feet (DSX-1)
# 1: 133-266 feet (DSX-1)
# 2: 266-399 feet (DSX-1)
# 3: 399-533 feet (DSX-1)
# 4: 533-655 feet (DSX-1)
# 5: -7.5db (CSU)
# 6: -15db (CSU)
# 7: -22.5db (CSU)
