9 - Using the BSMI R2 Signaling
Capability
This chapter describes R2 signaling as used with BSMI-level call
control.
The chapter has the following sections:
„ CPE Signaling Model
„ Enabling the R2 Protocol
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
