You must provide two unshielded Category 5 cables. The first cable connects the NT1 box to the
splitter, and the second cable connects the splitter to the wall jack.
There are RJ-45 connectors at both ends of the default orange ISDN S/T cable. However, an
RJ-45–to–RJ-11 ISDN S/T cable is available upon request if the wall jack at the site requires an
RJ-11 connector. Contact your router reseller for the appropriate cable.
