Frame Relay SVC Signaling and LAPF
Figure 1-5 shows the layers of protocol standards for frame relay signaling:
• The LAPF Core layer defines basic frame relay protocol for both PVCs and
SVCs and supports the reliable transfer of multiple numbered frames over
SVCs.
• The DLCMI layer defines link management protocol for PVCs.
• The LAPF and Q.933 layers define link management protocol for SVCs.
Figure 1-5. Frame Relay Signaling and LAPF Standards
The link access procedure, frame mode (LAPF) layer defines five unnumbered
control frames and three numbered supervisory frames on the communications
link.
