Interface cable

When a BSV interface works in user mode, it uses a straight-through ISDN S/T interface cable for
connection. At the two ends of the cable are RJ-45 connectors with pins 3 and 6 for data transmission
and pins 4 and 5 for data receiving.

When a BSV interface works in network mode, it uses a crossover ISDN S/T interface cable for
connection, with pins 3 and 6 for data transmission and pins 4 and 5 for data receiving. At one end of
the cable is an RJ-45 male connector for connecting the FIC-2BSV/FIC-4BSV interface and at the other
end of the cable is an RJ-45 female connector for connecting a TE device.
