TR TSY 000205 : ISSUE 1 SUPP 1

Presents Bellcore's view of proposed generic requirements for providing the ISDN Electronic Key Telephone Service (EKTS). EKTS allows an ISDN user to have access to multiple directory numbers (DNs), each with its own feature set. A given DN can also be accessed by more than one user (i.e., from more than one terminal) on the same ISDN interface and/or on different interfaces. Two or more users with access to the same DN can be simultaneously bridged onto the same cell on that DN. In addition, EKTS allows for the following capabilities: Hold, DN-Bridging, Intercom Calling, Abbreviated or Delayed Ringing Treatment on incoming calls, Station Ringing Transfer, automatically or manually invoked Bridge Call Exclusion, and Call Appearance Call Handling.
