ARGUS 25 - PRI Functions

* El-PRI interface in accordance with ETS 300011, ITU- T G.703-HDB3 code, automatic CRC-recognition; modes: TE (terminal simulation), NT (network simulation), Monitor (passive monitoring of the PRI access with online data logging on a PC)
* Automatic detection of the protocol and the configuration of the access: DSS1, 1TR6 or NO protocol, display of Layers 1-2-3 and the B-channel status * Layer 1 alarms (CRC-4, AIS, FAS, E-Bit, A-Bit, frame errors, code errors, Sa- bits display)
* Layer 1 Master/Slave mode
* Selectable additional protocol -CorNet-N. (Trademark of Siemens ICN)
* Automatic Service Test determines which ISDN services are available in send and receive direction
* Automatic test of the supplementary services -for 1TR6. interrogation of supplementary services -for DSS1: automatic tests of CLIP, CLIR, COLP, COLR, CFU, CFB, CFNR, AOC- D/E, DDI, SUB, UUS, support of keypad protocol * Telephony functions with the Call button, call number memory for lO numbers or keypad protocol commands, display of the calling and called numbers for incoming calls, selectable B-channel, en-block, or overlap signaling .Simultaneous use of multiple connections for self-call and loopbox
* Terminal or network simulation for different ISDN services
* Full text display of clearing causes ofa disconnect and the disconnecting location
* Sending charging information, date and time, calling party number in NT simulation
* BERT bit error test with evaluation in accordance with G.821/G.826 in an extended self-call or an end-to-end BERT, displays the bit errors and the bit error rate, permits injecting bit errors, BERT with adjustable Good/Bad threshold and OK/Not OK evaluation, bit pattern in accordance with ITU- T 0.150, adjustable measurement time, loopbox function for the B-channels and all services

* So-NT/TE functions like PRI .Automatic test of the supplementary services - for 1TR6: supplementary service test;
- for DSS1: automatic tests of CLIP, CLIR, COLP, COLR, HOLD,TP, CFU, CFB, CFNR, AOC-D/E, CCBS, call back when no response (CCNR), CW, ECT, 3Pty, SUB, UUS, keypad protocol
* Bus status test with interrogation and display and clearing of the active call diversions CFU, CFB, CFNR for all services
* Automatic X.31 (D) test: which TEI values are assigned to the access, simulation of a X.31(D) terminal to a X25 network
* Simultaneous use of two connections for self-call and loopbox
* Layer 1 tests and bus feed: measurement and evaluation of the phantom feed (OK, NORMAL or Restricted Power) and the L11evels ofthe ISDN send and receive signals of the NTBA or PBX
* Display of Layer 1 Info So-S4
* Cabling tests: Checks the bus terminating resistors, finds short circuit, crossed and broken lines. Results displayed in clear text
