25、 Unrestricted Digital Information with Tones & AnnouncementTECHNICAL REPORT NO. 65- 3 -5 Mapping Functions Between BICC Signaling Entity and B-ISUP Signaling EntityThe following subclauses list the information passed between the BICC signaling entity and B-ISUPsignaling entity:1) Binding information

26、,2) Bearer service information,3) Address information, and4) Cause information.The mapping reflected in the tables of this clause show the parameter names followed by theinformation contents in parentheses.The originating BIWF is always viewed as an originating exchange in the context of the B-ISUPs

27、tandards. Similarly, the terminating BIWF is always viewed as a destination exchange.5.1 Binding InformationBinding information is used to associate the call control signaling and bearer control signaling for theestablishment of an AAL Type 1 bearer connection. The Backbone Network Connection Identi

28、fier(BNC-ID) is carried by the call control in the Application transport parameter. The BNC-ID is carried bybearer control in the Application generated identifiers parameter.The mapping of the binding information between BICC signaling entity and B-ISUP signaling entity isshown in Table 1.Table 1Map

32、(AAL parameters)Table 3 shows the mapping between the BICC USI parameter and the B-ISUP Broadband bearercapability parameter and QoS parameter. This mapping is independent of the USI parameter codes.Table 4 shows the mapping between the BICC USI parameter and B-ISUP AAL parameters parameter.The mapp

33、ing is independent of the USI parameter codes, except for the B-ISUP Constant Bit Rate(CBR) and Multiplier subfields.Table 5 shows the mapping between the BICC USI parameter and the ATM peak cell rates (CLP=0+1)signaled in the ATM cell rate parameter. For each USI parameter code, a value for the pea

34、k cell rate isselected such that the bit rate of the corresponding N-ISDN service (e.g., 64 kbit/s, Nx64 kbit/s) can betransported as the cell payload of the ATM cells, i.e., excluding the overhead of the ATM cell and AALType 1 header.TECHNICAL REPORT NO. 65- 5 -Table 3Mapping of the BICC USI Parame

46、apping of cause valuesbetween BICC call control signaling and B-ISUPbearer control signaling at the interface between the BCF and CSF. Cause values related to specificbearer operations in B-ISUP are mapped to suitable bearer control related cause values in BICC. Thecause value mappings apply to the

47、case where the BCF can no longer establish or maintain the bearer.Mapping of B-ISUP connection clearing message cause values to BICC are only performed at the ISNthat set up the connection. The scope of the cause value mapping is from the bearer protocol to thegeneric BCF-CSF primitive interface and

48、 not directly to the BICC protocol.Table 7 identifies the Cause related information, derived from B-ISUP signaling, which is passed fromthe B-ISUP signaling entity to the BICC signaling entity via the BCF/CSF logical interface to provideCause indicators parameter fields giving details on the circums
