auroraDuet in tune with ISDN engineers The auroraDuet has been designed to provide the ISDN engineer with the right tool to resolve those difficult problems in the field under local or remote control. Available as a basic rate or combined basic and primary rate ISDN unit, the auroraDuet is easy to use, produces meaningful and understandable results, and provides the operational and functional qualities necessary to complete any task.
applications The ability of the auroraDuet to perform TE/NT emulation is the key to its versatility. For the Service Provider, whose primary concern is the provision and maintenance of ISDN capability, the strengths of the auroraDuet are evident when problems occour. ◆ ◆ ◆ ◆
Testing the local loop at the U-interface prior to installing the NT Using TE mode to simulate terminal equipment to validate line operation Checking cable continuity for S bus problems Monitoring of D-channel traffic to trouble-shoot the difficult problems
The auroraDuet is also able to simulate the operation of the NT and so appear as the network itself to facilitate checking Customer Premises Equipment. For the installation company, the auroraDuet proves itself as an ISDN equipment commissioning tool. ◆ In NT mode, commission and set up equipment prior to delivery to customer site ◆ In TE mode, validate the ISDN service provided to the customer site ◆ In LT mode, test the NT and subscriber equipment in the absence of a local exchange Save time and expense on site. Improve the quality of service to the customer. This ability of the auroraDuet to behave as both network and terminal equipment, proves invaluable to the maintainer of ISDN equipment. ◆ ◆ ◆ ◆
Monitoring and Diagnostic capability even under Remote Control Voice and Data testing S bus cable test option Wide range of public and private protocol capability
One tool to diagnose the problem in one visit. For the equipment manufacturer, the auroraDuet has the sophistication to be used in a development and manufacturing environment. ◆ Operating as a highly cost effective simulator and analyser ◆ In use as a highly configurable Quality Assessment tool ◆ Validating protocol development in a Software laboratory The auroraDuet makes it possible for ISDN users to validate the services expected to be available over the ISDN and to maintain their own private digital networks. ◆ Origination and display of Ð Calling Line Identity (CLIP) Ð Connected Line Identity (COLP) Ð Charging information ◆ Validates operation of Ð Direct Dialling In (DDI) Ð Multiple Subscriber Numbers (MSN) Ð User to User information The correct operation of these and many other facilities, will ensure that maximum benefit and return on investment can be extracted from the ISDN.
features Emulation Capability ◆ NT mode Ð emulates the network ◆ TE mode Ð emulates Customer Premises Equipment ◆ LT mode Ð emulates the Local Exchange looking towards the NT (not 4B3T) ◆ Phantom power for S-bus devices as well as power feed to Up0 interface ◆ B1, B2, Bx channel selection in Basic Rate modes ◆ Establish up to 30 simultaneous calls in Primary Rate modes ◆ Establish up to 15 simultaneous cross-connect calls in Primary Rate NT mode BERT Statistics ◆ Statistics conform to G.821 recommendations and are produced as absolute values or percentages ◆ Pass/Fail indication on timed tests specified against a pre-set threshold ◆ Results displayed on-screen or on hard copy using local printer on communications port ◆ Time stamping of individual events on printed output Multi-protocol/Multi-lingual ◆ Multiple protocols and monitor software stored on-board ◆ Down-loadable protocol updates from local PC to maximise the unit availability ◆ Selectable language options Voice and Data Testing ◆ 2.048/n x 64K Bit Error Rate Testing (BERT) ◆ Selectable pre-set and User defined patterns and time periods for Bit Error Rate Tests (BERT) ◆ Bit Error Injection Ð automatic or manual ◆ Automatic or manual call answer with data loopback ◆ Unattended mode with call screening ◆ Display of Bit Errors, Bits Received, Errored Seconds and Sync Loss during test Monitor and Analysis Capability ◆ Physical layer 1 monitoring using LEDs and Screen gives indication of Remote Alarm, CRC Error, Sync Alarm, Signal Detect, AIS, Activation, Info states ◆ On-screen Real time decode of D-channel activity ◆ Onboard storage of data for analysis with auroraExpert ◆ Remote Control operation from PC using screen and keyboard Automatic Service Tests for one key testing ◆ Identifies which services are available on the line under test ◆ Check the line configuration ◆ Check Quality of Service by initiating BER Tests ◆ Validates operation across all channels Supplementary Service Validation includes: ◆ Keypad support for * and # ◆ Hold/Retrieve ◆ Call Waiting, Forwarding (CFU, CFB, CFNR) ◆ Completion ◆ Closed User Group ◆ Terminal Portability ◆ 3 Party and Conference Calls ◆ Malicious Call ID
Packet Services ◆ Packet test function conforms to ITU X.25 ◆ Operates on D-channel on basic rate ◆ Generation of sequential packets for easy identification ◆ Configurable parameter set for X25 network ◆ Network and throughput confidence testing by counting transmitted and received data packets Battery/Mains Operation ◆ Rechargeable Nickel Cadmium battery ◆ AC/DC adapter for charging and mains operation Multiple Interfaces ◆ ÔUÕ interfaces for 2B1Q, 4B3T and Up0 ◆ ÔSÕ interface available via multiple connectors for Basic and Primary rate ISDN
