Does anyone know any source to find datasheets about Alcatel PDH and SDH (1650 and 1511) and related cards?
Thank you very much.

I have some info about 1660 not about 1650. do you need it.

Here is Alcatel 1660 SM Release 5

Thank you for your help.
Do you know any resource to find more detailed information about Alcatel PDH and SDH cards such as FXO, FXS, RAC, or different I/O card?
