Hi H, What you need is a normal Straight through Ethernet Cable to connect from the Slimline-2 or Slimline-6 directly onto a Cisco 2503 ISDN Interface.
You could use the same Ethernet Straight-Through cable if you have ISDN at your home to connect from the NT1 to an ISDN Device. An Ethernet Cross-Cable will not work. Hope this helps. Regards, Brian.
