Setting the Switch Protocol

Find out what kind of ISDN switch the local CO is using by asking the telephone administrator or telephone company representa- tive. Configure the ISU 2x64 for either Northern Telecom DMS- 100, AT&T 5ESS¨, or a switch conforming to the National ISDN-1 standard (usually an AT&T 5ESS, NT DMS-100¨, or Siemens EWSD). For switches outside of North America, use the Euro IS- DN, VN4, TDX10, TDX1B, KDD, NTT, or NEC switch types.
