ISDN S interface cable wiring diagram. Both ends are wired identically.
HOT TIP!
This cable has 4 twisted pairs wired "straight through" just like the cable normally
used for Ethernet 10 Base- T. The wiring configuration is the same as TIA/E- 568- A
T568A (T568B is electrically equivalent).

The outside pairs (Brown and Green) are often not required and may be omitted.
