The complexity of installing and troubleshooting ISDN BRI has continued to be an obstacle due to the lack of standardization and the variety of calling types, Service Profiles, and other parameters that a field technician must know in order to install a service. Furthermore, physical layer impairments, such as load coils, lengthen the time for service deployment and subsequent revenue generation. Fortunately, the TPI-500 provides a number of features that make it the easiest, complete field tester for the installation and maintenance of ISDN BRI service.
The TPI-550 offers a full array of features, functions, and performance capabilities to turn-up and troubleshoot Basic Rate ISDN, EBS (P-Phone), and POTS and supports all US call controls and ISDN central office switches. NT1/TE, NT, and LT emulation, 40 Khz measurement, and Layer 3 English decodes make it ideal for the installation and troubleshooting of ISDN BRI service. Features such as Auto SPID, SPID Guess, test macros, and configuration downloads make the TPI-550 easy-to-use.
This compact, handheld instrument can be used for BRI testing both at the consumer premises equipment (CPE) and also at the central office (CO). An all-weather solution, the TPI-550 is ideal for portable ISDN BRI testing and can be used in al conditions, from inside an office environment to a noisy, wet outdoor span repeater. A built-in speaker and microphone enable hands-free operation and an optional handset can be used in high-noise areas. For protection, connectors are secured behind a weather-resistant lid.

Line Qualification:
Typically, a 40 Khz loss is measured to ensure that it meets line requirements. In addition, the TPI-550 can be placed into an LT or NT mode and send/respond to EOC loopbacks providing a method of testing the 2B1Q BRI signal quality of the BRI line. Testing in either mode, the unit can now run a BERT test on either B-channel, both B-channels (2B), or the entire line (2B+D), using patterns such as 2047. This test verifies the U interface.
Service Verification:
Once the physical layer has been tested, the actual BRI service can be tested by placing and receiving calls, which verify proper switch translations. The TPI-550 can place and receive these voice and data calls toayer 1, 2, and 3 results, including plain English decodes of D-channel cause codes
