							Enabling the R2 Protocol
	Table 18. R2 Digital Line Signaling Parameters (Continued)
Name			Description	Units		Range
c_d_cas_bits			Specification of the CAS C			0: CD=00
			bit and D bit settings.			1: CD=01
						2: CD=10
						3: CD=11
ClearbackControl			Used by the outbound side			0: release guard
			to determine whether the			1: forced release
			network will use a release
			guard (AB=11) or a forced
			release (AB=00) signal to
			tear down a call, The
			selected signal is handled
			accordingly, while the
			other is simply ignored.
	Table 19 identifies the IISDN_R2_INTERREGISTER_PARAMS
	sub-structure containing the parameters required used to configure
	the MFC inter-register signaling.
