9. DLCI
The DLCI is the layer two address for FR. For transmitted frames , the DLCI is the destination address, and receiving frames it is the source address. it is two types a) Global DLCI b) Local DLCI

12. Types of Virtual circuit over FR

13. FR (Frame Relay) Design
There are three component of FR- Access: the local loop from customer site to the FR service provider’s point of presence (POP) or central office Port: The FR access port is the speed of the connection into the FR service provides switch. Virtual Circuit: it is two types PVC and SVC

20. PVC Management , or LMI
It is the control signaling between a CPE device and a FR network switch.
