GL’s LinkTest™ family are sophisticated bit error rate testers in a compact, hand held packages with single or dual interfaces. The units can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU/DSUs, T1 CSUs, DTUs, NTUs and TIUs.

Capabilities

The LinkTest™ family is designed to fulfill the requirements of a broad range of applications that may be used to test data communications equipment, networks, systems and line facilities. It simulates real data passing through a data communications link, and then determines the performance of a piece of equipment or that of a network. Many standard data patterns may be generated and recovered. The LinkTest™ can then monitor the data passing through the data communications link, and indicates line quality by comparing the data that has been received with the data that was known to have been transmitted.
