This chapter describes R2 signaling as used with BSMI-level call 

control. 

The chapter has the following sections:

„

„

Brooktrout boards offer E1 CAS signaling for customer premise 

equipment (CPE).

The protocols supported are:

„

ITU's R2 (Line Signaling and Inter-register Signaling) and 

national variants

„

LEC protocols (Wink Start, Delay Dial, Immediate Start, FXO 

Loop Start, FXS Loop Start, FXO Ground Start, FXS Ground 

Start)

Dialogic's implementation of the R2 protocol contains a number of 

parameters that are used to configure the module to conform to the 

ITU recommendations (refer to ITU Blue Book, Signaling System 

R2, Volume VI Fascicle VI.4, Q.421 - Q.424, digital line signaling, 

and Q.440 - Q.458, compelled inter-register signaling). The fully 

embedded R2 protocol stack consists of digital line signaling (R2
