BCC and ITC Determination on Calls from ISDN-PRI Trunks to 
Endpoints  (GRS not Involved)
NOTE:
The system does not use ITCs when terminating to an endpoint.
Considerations
nACCUNET and SDDN Services
The system will be able to use ARS ta bles to route c alls to these  networks. 
For exam ple, BCC 1 is a 56 k b ps service.   If an ACCUNET 56  kbps 
Service trunk group is in a routing pattern that uses GRS, BCC 1 should b e 
set to yes.

nIntegrated Access on Non-ISDN-PRI Trunks
The T1 carrier access to the AT&T serving office will  allow sharing of the 
same trunk group for voice and data calls. For example, the same trunk 
group may carry both voice calls (requires a BCC of 0) and Mode 1 data 
calls (requires a BCC of 1).  This situation requires the trunk group 
preferences in the ARS routing pattern to be administered with a ‘‘yes’’ for 
both BCC 0 and BCC 1.

Call (CBC) Service Selection allows the dynamic identification of a s pecific 
service type request on a per call basis.   For CBC Service Selection 
feature, the trunk group is administered as CBC....
