Professional Measurement on SHDSL 4-Wire Accesses

May 2007, SHDSL 4-wire accesses are gaining market share both abroad and here at home. Therefore, intec's ARGUS 145 - its most flexible handheld tester – is now also available with additional measurement functions for SHDSL 4-wire lines. Those who already have an ARGUS 145 tester can upgrade it to add support for testing SHDSL 4-wire accesses. Like all of the ARGUS 145’s other functions, the SHDSL 4-wire functions can be conveniently selected from the menu at the press of a softkey – no module swapping is necessary. The SHDSL 4-wire option completes the ARGUS 145’s extraordinarily broad repertory of supported access types: In addition to its support for SHDSL 2 and 4-wire lines, it also offers tests for ADSL, ADSL2 and ADSL2+ as well as for POTS, U-interface and BRI accesses.

Comprehensive Test Functions
The complete suite of tests and operation modes, which the ARGUS 145 already offered for SHDSL 2-wire lines, are now also available for the SHDSL 4-wire variant. This suite of tests includes among others IP ping, traceroute, download and upload, bridge and router functions plus VPI/VCI scan, ATM OAM ping and OAM loop tests. In addition, the ARGUS 145 can count the number of repeaters used in the route. The tester supports both the STU-R and the STU-C mode. It is also possible to use the ARGUS 145 on a TDM access.

The options available for the ARGUS 145 include support for VoIP terminal simulation, statistics functions as well as a function for evaluation of IPTV and VoD data streams. Furthermore, the tester offers an Ethernet Through mode as well as a Router Replacement mode with support for DHCP (Client and Server). Resistance and capacitance measurements are available to check the physical characteristics of the subscriber’s line. On 4-wire accesses, the ARGUS 145 displays the measured connection parameters by wire pair.

On a 4-wire interface, the ARGUS 145 achieves a data rate of 4608 kBit/s in accordance with the ITU-T 991.2 Annex A and B standards.

The next release of the ARGUS 145 will also offer enhanced SHDSL measurement options for both 2 and 4-wire lines. Existing ARGUS 145s can then be updated to support this additional functionality by simply downloading the associated firmware update.
