I am trying to rollout a site in Japan. I got struct while connecting the INS 1500 PRI from service provider(NTT) DSU.The jack used in NTT-ISDN DSU Look like RJ-45 but when we try to connect using RJ-45 connector we are unable to do so. Below is the photograph of Connector and female port.
Did any face the same issue? Need help on what type of connector it is and wire positions in connector .
