When we do DSL, we service everything out of ADSL2+ combo cards on Zhone
MXK gear.<br><br>
-Integrated metallic testing on the combo cards helps reduce truck
rolls<br>
-Having dialtone on the pair helps with identifying pairs in the field
using ANAC<br>
-Having dialtone on a pair provides sealing current<br>
-Having dialtone on a pair stops other techs from "stealing"
the pair for something else, because they think it isn't in use<br>
-Derived voice (VoIP on CPE) makes the voice more subject to line
impairments, etc.<br><br>
At peak we had around 6000 leased CLEC copper pairs from the local
ILEC.<br><br>
Just notes from personal experience.<br><br>

Because it is cheaper and easier? It is a lot of equipment there simply
does not need to be there. If you have DSL you have CPE equipment and
that CPE equipment can have FXP out for very little extra. You also save
having filters to separate� DSL and voice.<br><br>
In any case, even the ILEC here is dropping analog and delivering phone
services via VoIP and FXP out on the CPE. I believe because the
technician� only needs to go to the DSLAM to connect you. If you are also
getting analog voice, he needs to go to the CO too because voice and
DSLAM are no longer cohosted.<br><br>
