Btw, my reference is Cisco Frame Relay Solutions Guide under the
"Frame Relay Switched Virtual Circuit (SVC) > Monitoring Frame Relay
SVC" section.

Its a bit of a tricky question because LAPF core is basically the
framing of Frame Relay user frames and LMI frames. However, the
operational state in a "sh int" refers to the SVC signaling.
