Protocol State Transition Specification

Each of the following is an array of length 16. Element zero is invalid and elements 1-15 correspond to R2 MF signals 1-15. These allow the Call Setup Service Pack software to construct the proper state transition tables for a given trunk.

Forward Channel Signal Definitions

endOfANI_Available

Signal end of ANI identification

InfoNotAvailable

Indicates that ANI information is

to distinguish from signal

 

 

 

“aniRequestNotAccepted”.

 

 

 

 

 

 

aniCategoryDefault

Default Group 1 category. Used if

category is not specified in a given

 

 

 

call request.
