I have an ISDN link from place A to place B. The configuration is such that router at place A dials or calls router at place B.When ever the link is normal, at the command “Show ISDN status” in the router at place A, I get “layer 1 active”.
Now when place A routers link is up does this layer (Place A) remain active even when the called router’s (place B) isdn line is down?
