"Integrated metallic testing on the combo cards helps reduce truck rolls" I can't stress this feature enough. Being mainly a data only CLEC, we wanted to buy the cheaper, non-combo, data only DSL cards. However, Adtran, Calix, Zhone, and Nokia confirmed that without the SIP to FXS combo function, you loose the Integrated metallic testing" This means you can't test loop length (without a dsl modem trained on the other end), can't test if you have a cross, foreign voltage, etc. Yes, this can be done with a field tester, but the cost of sending a tech out to do that is much more of an expense.

and what is an FXP? I think you mean FXS port.
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
wasnt there a hige shit stom in australia for their new national broadband network making internet ptrimary and phone secondary, a lot of aussies on forums I frequent bitch about its reliability, where even their aged copper services worked fine, not to mention prolonged outages due to storms and the bushfires they had recently, lets hope the world learns from australias mistakes and not go down that path.
