Need help finding CAIS SDSL equipment manual

Hi all, I'm looking for CAIS SDSL equipment manual. I know there is no more CAIS, but I really need their equipment manual/documentation. If somebody worked before for CAIS/Ardent Communicataions or somebody knows the person who worked before for CAIS/Ardent please let me know. It would be really helpful for me. I appreciate if somebody can help me in this regard. thanks in advance, Ganbold
