If, on the other hand, a Bearer Capability of Unrestricted Digital Information is specified, then the network is required to set up the call using only end-to-end digital facilities (without the use of robbed-bit signaling, echo cancellers, DCME nor A-law to mu-law conversion), or reject the call if no end-to-end digital circuit is available.
