Switch Protocol

Find out what kind of ISDN switch your local CO is using by asking the tele- phone administrator or telephone company representative. Configure the ISU

128 for either a Northern Telecom DMS-100®, AT&T 5ESS® switch, or a switch conforming to the National ISDN-1 standard (usually an AT&T 5ESS, NTI DMS-100, or Siemens EWSD). In the Far East, configure for the NEC switch.

Call Type

The call type can be configured four different ways, depending on the type of service used: speech, audio, data 56 kbps, or data 64 kbps.

When placing outgoing calls using the optional V.34 modem, the unit must be op- tioned for either speech or audio call type.
