ABSTRACT: This document replaces TA-NWT-001310 and TA-NWT-001310-SUP01.
Integrated Services Digital Network (ISDN) Call Deflection (I-CD) is a set of features that provide ISDN users with the capability
to respond to an offered call with a request for their serving switch to deflect the call (i.e., redirect the call) to another user
identified in the request.
The deflecting user retains an association with the call until it is successfully offered to the user identified in the call
deflection request or until the deflecting user clears from the call. If the deflection attempt is unsuccessful, the deflecting user
may send another deflection request, answer the call or clear the call.
This document provides switching and signaling generic requirements for Call Deflection for Class II equipment on Primary Rate
Interfaces (PRI). However, the calling and deflected-to users may be non-ISDN users, or ISDN users served by Class I equipment on ISDN
Basic Rate Interfaces (BRIs) or by Class II equipment on PRIs.
The GR also defines two additional subscription options, Call Deflection After Answer (CDAA) and Call Return. These subscription
options offer incremental capabilities and are applicable once the user is subscribed to the basic feature.
