VI. Common-mode fast transient pulse immunity
The signal & data line between CDMA cabinets and that connected with other systems
(such as E1 trunk line), control line and cable connected to DC input/output port, should
satisfy the requirements for fast transient pulse immunity. The indices are shown in
Table B-8.
