24、ndard for Telecommunications - Supplement to T1.666-1999, Interactions Between the Operator Services Network Capability (OSNC) and Release to Pivot (RTP) Annex T (normative) 1 Introduction This Annex describes the additional functions that the Operator Services Network Capability (OSNC) - described

25、in T1.666-1999 - will need to perform when invoking the Release to Pivot (RTP) network capability - described in T1.661-1997. These functions are activated on a per-switch basis and are only activated when the Release to Pivot network capability is also active. In particular, the originating end off

26、ice and the operator services switch may activate these functions independently, though RTP will not be invoked for a given call unless both switches have these functions active. This Annex applies to an OSNC Originating Connection or to a Type 2 Transfer Connection. No additional changes to the sco

27、pe, purpose and application of the Operator Services Network Capability are required. 2 Normative References The following documents contain provisions that, through reference in this text, constitute provisions of this American National Standard.

31、. The operator service may then invoke RTP when a new destination is determined for the call. Additional information may be exchanged to facilitate: returning the call to the RTP-invoking exchange, notification to the RTP-invoking exchange of the disposition of the call, and proper accounting1. 4.2

On invocation of RTP at AC1 by AC2, AC1 is able to: monitor the pivoted call to provide notification to AC2 of the dispositio

35、n of the call. store information from AC2 to be returned to AC2 in the event the call is returned to AC2. monitor the call for the “#” or “*” indication that the call should be returned to AC2 and optionally collect user digits to be forwarded with the call setup. The “#”and “*” indications are spec

36、ified in T1.401-1993, using the frequency pairs 1477/941 Hz and 1209/941 Hz, respectively. use the RTP “return to invoking exchange” function to return the call to AC2, optionally using routing information supplied by AC2. 4.4 Description of Functional Entity AC2 AC2 provides operator-services speci

37、fic functionality in support of the invocation of RTP. On receipt of a call offering RTP with a reason of “OSNC,” AC2 is able to: alert the invoking service of available OSNC-related functions allowed on the call. respond to a request from the invoking service to invoke RTP to deliver the call to a

38、new destination, including information required to support the desired OSNC-related functions. receive notification of disposition of the call after the call has been released to AC1. deliver to the invoking service a call received by FE3 with an indication the call is being returned to AC2 followin

39、g detection of a requested “#” or “*” signal from the user. The “#” and “*” indications are specified in T1.401-1993. 5 Information Flow Model During initial call setup, OC1 is enhanced by the functions of AC1 to invoke RTP. RTP functionality is used to indicate that RTP may be invoked “Any Time Dur

40、ing the Call” and to indicate “OSNC” as a reason for invoking RTP. Other services and network capabilities may add additional RTP reasons. AC1 functionality is used to pass additional information with the CALL REQest, as detailed in the protocol and procedures. When the call is released by AC2, RTP

41、functionality is used to indicate that the reason RTP is being invoked is OSNC. AC2 may pass additional information with the Call Disconnect, as detailed in the protocol and procedures. AC1 is an extension of, and resides in the same node as, OC1 functionality. AC2 is an extension of, and resides in

42、 the same node as, either OC2 or TC2.
