Please could someone give me the type of cable and connector which I have to connect to the EM-HDA-6FXO module in other to connect the PSTN lines to a Cisco voice gateway 2821 ?
Thanks in advance !
Preferentially, you will need the BlackBox JPM2194A patch panel with RJ21 cables, as indicated in the data sheet:
Else, any RJ21 cable and patch panel will work.
