Interface cable

When a BSV interface works in user mode, it uses a straight-through ISDN S/T interface cable for
connection. At both 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 plug for connecting the BSV interface and at the other end of the cable is an RJ-45
receptacle for connecting a TE device.
