Enabling the R2 Protocol

November 2009

347

The MFC inter-register protocol is specified through a subset of the 

 that define the following:

1. Signal meaning definitions (events).
2. Actions associated with a given signal event. These specifications 

are used to create a set of state transition tables for the desired 

variant.

3. Protocol control parameters.

The parameter set might require extensions as support is added for 

variants unidentified at this time. In addition, for a given variant, 

certain signals and actions might not be defined. This restricts the 

way in which the protocol can move through the processing states.

conditions indexed by enumeration 

IISDN_R2MFCP_GROUP_B_

CALLED_LINE_CONDITIONS.
Only a subset of these signals are 

used in a given protocol variant. 

Set those that are not used to the 

“invalid” tone code.

Array of IISDN_CPGEN_MF_

PARAMS structures that define 

the characteristics of the RING and 

BUSY call progress signals. RING 

must be defined as cpSignals[0] 

and BUSY must be defined as 

cpSignals[1].
