is based on the distance from the FRX4000 to the external T1 device, and is normally
dictated by the telephone company that supplies the line.
Clocking
determines whether clock will be generated by the FRX4000 T1 port (
Master
) or the
remote device (
Slave
).
Base Chl Speed
determines the line speed over each channel.
Starting Chl Number
determines the lowest channel number that will be used.
Num of Chnls
is the number of channels that will be used on the T1 line.

Y
) the generation of CRC-4 (polynomial X4 + X + 1).
