When a router is connected to a Frame Relay WAN link using a serial DTE interface, how is the clock rate determined?

A Supplied by the CSU\/DSU
B By the far end router
C By the clock rate command
D By the Physical layer bits stream timing

Correct Answer: Supplied by the CSU\/DSU

Clocking on a serial interface is always provided by the CSU/DSU (DCE device). However, if you do not have a CSU/DSU in your non-production test environment, then you need to supply clocking with the clock rate command on the serial interface of the router with the DCE cable attached.
