ISDN PORTABLE TEST SET
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
