Note:
1. Test method is the same as IEC 61000-4-2 [5].
2. ESD should be performed to all exposed surface of equipment to be tested except those to be
protected as required by the user's document.
4) RF conductive anti-interference
In CDMA equipment, the port where a cable of more than 1 meter may be connected
to, including control port, DC input/output port and the input/output port of the
connection line when cabinets are combined, should satisfy the requirement for RF
conductive anti -interference. Voltage level is shown in Table B-6.

5) Surge
For CDMA equipment, the DC power input port, indoor signal line of more than 3 m,
control line (such as E1 trunk line, serial port line) and the cable that may be led out
to the outdoor should all satisfy the requirement for surge interference level. The test
level is shown in Table B-7.
