Frame Relay Accesses
However, under the above stated conditions, the network configuration shown below would not
be allowed:
Switched connections can only be used as a backup to frame relay. As such, a switched connection
would be made to a given node connected by a frame relay access only after that frame relay access
had failed. Switched and packet mode services will not be allowed to connect any given two nodes
simultaneously. The following diagram is provided as an example. The INS 64 connection between
sites SITE1 and SITE2 would only be made if the frame relay connection was somehow lost.
