FRX6000 ports 0–7 on each RLP are determined by the Line Interface Card(s)
and attached cables. The RLP record identifies the LIC, and only the valid inter-
faces will be displayed on the Port screen, among:

is the data transmission rate in bits per second, and the clock speed on a non-T1/E1
serial port when the port is a physical DCE (i.e., the attached I/O cable is DCE). If this
port is a physical DTE, specify the line speed that matches (as closely as possible) that
of the device connected directly to the port.
Selecting this parameter for an FRX4000 DSU port will toggle between the two valid
