Enabling the R2 Protocol

November 2009

347

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

parameters in

Table 17

on

page 338

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.

groupB_LineConditions

Structure of Group B called line

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.

Refer to

Table 22

Call Progress Signal Generation

cpSignals

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].
