出售 LinkTest™ Single

Overview

The GL’s LinkTest™ SINGLE is a sophisticated bit error rate tester in a compact, hand held package. The unit can test a wide variety of communications facilities and equipment including Asynchronous (full-duplex and half-duplex), Synchronous, T1, fractional T1, E1, fractional E1, modems, multiplexers, CSU/DSUs, T1 ESF CSUs, DU, NTUs and TIUs. The LinkTest™ SINGLE is supplied with V.35, RS232, RS422/RS530, X.21, DS1 (T1, 1.544 Mbps) and G.703 (E1, 2.048 Mbps) interfaces. The tester is supplied with a wall-mounted AC transformer.

Applications

The LinkTest™ SINGLE 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™ SINGLE can then monitor the data passing through the data communications link, and indicate line quality by comparing the data with the received data that was known to have been transmitted.

Typical applications include,

• Final test departments
• Field installations of data communications equipment
• Field evaluations of data communications equipment
• Field monitoring of data communications facilities
• Field problem isolation

LinkTest™ SINGLE can test:

• Async Mode - Tests asynchronous modems and CRT terminals
• Sync Mode - Tests the customer interface on DDS, T1 and T3 CSU/DSUs, mux channels and synchronous modems
• T1 Mode – Tests T1 lines, CSU/DSUs both short and long haul, T1 mux and drops from T3 mux
• E1 Mode – Tests E1 lines, NTUs and DTUs, E1 mux and drops from T3 E3 mux
