[Asterisk-Users] Zaptel Line Build Out

[Rod Bacon]

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?
