1 AuroraDuet Test Equipment Hand-held testing for Basic & Primary Rate
2 The AuroraDuet is the total solution to problem issues associated with the operation of the. Available as a Basic Rate or combined Basic and Primary Rate test instrument, the AuroraDuet provides a complete range of test functions from the very basic to the very advanced. With this instrument, the engineer can maintain the integrity of the circuits and equipment under his control at any time. This hand-held unit is an ideal instrument for the field engineer dealing with the simplest of line installations yet sophisticated enough to be used in a laboratory to validate the operation of new developments. The extensive functionality of the AuroraDuet makes it ideal for all applications that engineers in the field can experience. Much thought has gone into the actual operating requirements of the tester. The logically constructed menus for configuration and operation are supplemented by single key selections for commonly needed functions and service tests to save time. The unit s size and design means that virtually any location where it is possible to install equipment is accessible to an engineer with an AuroraDuet, including areas of poor light quality. The AuroraDuet is also capable of being totally controlled remotely by an engineer using a PC connected directly to the tester or across the PSTN. AuroraDuet The total solution to testing The AuroraDuet is a key asset to all business activities involving. Service providers can make extensive use of the U interface and V5 monitoring capabilities. Organisations concerned with the commissioning and installation of equipment can profit from the simulation capability. Companies involved with maintenance and troubleshooting will find the monitoring and analysis functionality invaluable. Manufacturers of equipment can use the AuroraDuet as a Quality assessment tool, and users of services can ensure that the services are as expected and as an arbitration tool between different suppliers in their environment.
3 What are the key testing applications? Simulation The AuroraDuet can simulate on the Basic Rate S/T or U reference points allowing a full combination of TE, NT and LT modes including EOC loopback commands and on the Primary Rate interface in TE or NT mode, either directly on the exchange or at customer premises. Multi-channel simulation: Phantom power for NT1, S-bus devices as well as power feed to Up0 interface B1, B2, Bx channel selection in Basic Rate modes Automatic B-Channel Cross Connect on Basic Rate for mini-switch simulation Establish up to 30 simultaneous calls in Primary Rate modes Establish up to 15 simultaneous cross-connect calls in Primary Rate NT mode Traffic generation capability using automated tests Physical layer testing and Link Quality assessment When a call fails or call set-up problems exist it is essential to have an instant readout of the physical layer quality indicators to help isolate customer equipment problems. The AuroraDuet offers hotkey access to view instantly G.703 and G.704 error counts and messages when in monitor or simulation test modes. When installing or maintaining coaxial or twisted pair cabling for 2Mbit/S links the cable digital quality will need to be determined. This can be achieved by terminating each end of the link (receive and transmit paths) with an AuroraDuet running a wide-band bit-error-rate-test (BERT) across the link. Physical layer 1 testing and monitoring using LEDs and Screen gives indication of Remote Alarm, CRC Error, Sync Alarm, Signal Detect, AIS, Activation, Info states and a number of other key indicators. Selective BERT capability for both Basic and Primary Rate circuits, including Nx64k multi channel 2MB framed and unframed BERT capability for PCM circuit testing 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; Origination and display of Calling Line Identity (CLIP), Connected Line Identity (COLP), Charging information; Validates operation of Direct Dialling In (DDI), Multiple Subscriber Numbers (MSN), User to User information, Alpha-numeric subaddressing. Teleservice & Supplementary Service Testing AuroraExpert PC analysis package Monitor Mode Automatic Service Tests for one key testing NT Mode TE Mode Monitor Mode LT Mode Check the line configuration Check Quality of Service by initiating BER Tests RXB RXA Validates operation across all channels PBX NT X25 Central Switch Identifies which services are available on the line under test and therefore those which are not.
4 Monitoring Protocol Monitoring, Trace and Analysis It s not enough to know what is wrong, it s knowing why it s wrong. Capture the awkward, intermittent errors that cause the underlying problems. What are the key testing applications? On-screen Real-time decode and trace of D-Channel activity Filters allow specific protocols to be selected with frame timestamps Many filter and trigger criteria including layer, call reference, SAPI, TEI, and many more for initiating call tracing and monitoring B-Channel monitor on selected time slots Onboard storage of data for analysis with AuroraExpert TE NT AuroraExpert real-time protocol analysis
5 International, National and Private protocols enables engineers to work on a variety of equipment and mixed protocol networks without using a different tester. Also provides identification and decode of encapsulated protocols in B-Channel including PPP/IP. ETSI, EDSS1, 1TR6, VN4, TPH, DASS, DPNSS, QSIG, CorNet-N, CorNet-T, CorNet NQ, TN1R6 X.25 D & B-Channel IP protocol decode support conforming to RFC1490 Holds over 16 protocols on one tester which means the right one should always be to hand LT Access Network V5 ETSI Monitor QSIG QSIG NT CorNet-N CorNet T Monitor TE Full remote operation PC control through Virtual Instrument representation of the AuroraDuet Up to 20 instrument and location profiles for central testing control. Analyse the remote traces with AuroraExpert Remote testing and diagnosis Intermittent faults may result in many unproductive and costly site visits before the fault is observed. The AuroraDuet may be controlled remotely via a PSTN modem or TA. This will allow real-time testing to take place or tests to be set running with dial-up and download of results later. Virtual AuroraDuet S-Bus PC TA TA Modem PSTN Modem Remote Monitor or Simulate Direct Cable Connection
6 Fully decode all V5.1 and V5.2 protocols Decode encapsulated and X.25 signalling (user signalling) V5 Protocol Monitor With access networks providing the means to accommodate mixed technologies across multiple E1 spans, monitoring and decoding the traffic over these interfaces is crucial in determining where cross protocol errors may occur. The AuroraDuet provides an automatic link protocol scan to identify C-Channel protocols, LAPD signalling and link configuration. Scan and identify C-Channel protocols and link configuration Drop any timeslot to the AuroraDuet communication port Extensive on-tester filtering; protocol, LFA, layer and lots more Mixed Technologies PSTN V5.x E1 Link Access Network Leased Line LE-Local Exchange
