TPI 570

The increasing complexity of ISDN infrastructures makes meeting customer requirements for service and reliability more challenging than ever before. In addition, the increased use of HDSL and HDSL2 fed T1 lines, have driven costs down and demand up.

An increasing number of customers are choosing to satisfy their voice and data needs with ISDN PRI service, due to its flexibility and upgradeability in the future. In this high demand and competitive telecommunications environment, technicians require an easy-to-use, portable test set that can handle the installation of the ISDN service, the first time out.

The TPI-570 enables testing of primary rate ISDN circuits at the customer premises or at the central office cross connect panels. It tests 23B+D circuit configuration or a NFAS 23+D and 24B configuration, and verifies bearer services carried on a BRI ISDN circuit.

It can test BER across any combination of channels and can emulate a network NT2 or the CPE. Furthermore, support
for all US call controls, including National ISDN provides unmatched flexibility in turning-up and troubleshooting ISDN services. With the basic rate ISDN option, it can be used at either the 2-wire U interface, or at the 4-wire S/T interface. The TPI-570 can support test call placement, errored second testing, network originated loopback testing, and BERT for both services.

This compact, handheld instrument can be used for PRI and BRI testing (optional) both at the consumer premises equipment (CPE) and also at the central office (CO). An all-weather solution, the TPI-570 can be used in all 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
