FRX4000 ports 2 and 3 are determined by the attached cables:

FRX4000 ports 4–7 are determined by the expansion Line Interface Card (LIC)
and attached cables. RLP Configuration identifies the LIC, and only the valid
interfaces will be displayed on the Port screen, among:

available by special order.) Note that a T1 or E1 LIC supports one port (port 4).
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-

is the data transmission rate in bits per second, and the clock speed on a 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 CSU/DSU port will toggle between the two
valid values of
56K bps
This parameter cannot be selected on a T1 or E1 port; rather, the line speed is deter-
mined by the port type and channel usage:
