Abstract: Certain aspects are directed to an interceptor system for characterizing digital data communicated between certain points in a telecommunication system. The interceptor system includes an interface device and a processing device. The interface device can retrieve data from at least one communication link between a radio frequency processing unit and a baseband processing unit of a telecommunication system. The data includes digital data communicated between the radio frequency processing unit and the baseband processing unit. The processing device can determine an interface link protocol for communicating with terminal equipment via the telecommunication system. The interface link protocol can be determined based on an organization of the data retrieved from the communication link.

Abstract: A passive intermodulation (PIM) tester is provided. The PIM tester includes at least one interface to couple the tester to a front-haul communication link used for communicating front-haul data to a remote radio head (RRH) having one or more antenna ports. The PIM tester includes a programmable processor, coupled to the interface, configured to execute software, wherein the software is operable to cause the tester to do the following: identify at least one tone in at least one downlink band of the remote radio head, wherein potential PIM products may appear in at least one uplink band of the remote radio head in response to the identified at least one tone; inject the identified at least one tone in the at least one downlink band of the remote radio head; and monitor the at least one uplink band for the potential PIM products from the injected at least one tone.
