Information

The Tele-Path Model 570 ISDN Portable Test Set is a compact, battery operated device used to conduct testing of Primary Rate ISDN circuits at the customer premise or main distribution frame. The Mode! 570 is designed both for rugged durability and ease of use, with menu driven screens. The Model 570’s operating modes allow it to function in a Terminating mode, acting as the NT2 and Terminal Equipment (NT2/TE), or in a Bridge mode allowing monitoring of an operational PRI circuit. Depending on the BR! Basic Rate Interface (BRI) option installed, the unit’s BRI mode selection enabies the unit to function at the "IT Interface as a Network Termination (NT1), Terminal Equipment (TE), or NT1/TE combination, Line Termination (LT), or in a Monitor mode; or at the "S/T" Interface as TE or in a Monitor mode. The Model 570 allows testing of a 23B+D circuit configuration or a dual span 23B+D and 24B configuration. Multiple 24B circuits may be tested by keeping the controlling D channel span up and successfully connecting and testing additional 24B circuits. The D channel time slot is selectable so that individual trunk groups, with their own D channels, may be tested. Call controls include NORTEL (DMS), AT&T (5ESS), and National ISDN-2 (includes NORTEL, AT&T, and Siemens). The Model 570 capabilities also include: • Selectable Voice and Data capability, using multiple B channels in the Data mode • Simultaneous B channel calls - Origination on one B channel and recieve on another • Multi-call capability (up to 23 of any combination) • Auto answer incoming calls . BERT - T-1 with QRSS - B channel with 2047 (any combination of B channels within a PRI span) • DSL ESF EOC channel status including loopback response • Block error testing • Speed dial memory • Layers 1,2, and 3 message analysis • RS-232 Data port with real-time monitoring of D channel, D channel decode and display of messages • Battery operated
