CPE Signaling Model

November 2009

341

 illustrates an example inter-register exchange in which 

the inbound protocol is configured to collect DNIS digits first, 

followed by collection of ANI information, and concluding with the 

exchange of DNIS category and called line condition. However, 

variations on this exchange are possible, resulting from different 

settings of the inbound protocol control parameters and the absence 

of certain signals in a given variant. For instance, the inbound 

protocol is configured to request ANI information following reception 

of N DNIS digits. Following completion of ANI collection, the DNIS 

collection is resumed. Another example is that a certain variant 

might not define the forward signal that indicates the end of the 

DNIS string. In this case, the inbound protocol must count the DNIS 

digits and signal a request for other information when the required 

number of DNIS digits has been collected.

protocol control parameters, protocol signals, and protocol processing 

actions provided by the Brooktrout R2 stack.
