ISDN71
ISDN CARD FOR MULTI INTERFACE TESTER D2071
OVERVIEW
The D2071 multi-interface tester extends its action field by adding the
capability to investigate the ISDN world. This is achieved with the ISDN71
module that integrates the Aethra long-time experience on ISDN in the new
generation modular tester.
The card is able to characterize the S/T interface completely, allowing a full
control of the communications occurring between TE and NT; the devices
themselves can be checked as well.
The available operating modes permit the simulation of both the Terminal
Equipment and the Network Termination; in addition to these ones, the
instrument can carry out a high impedance monitor on the S/T bus.
On the other hand, the background monitor allows the user to execute a
test and concurrently capture the D-channel signalling protocol. The
acquired trace can be immediately analyzed on the screen or uploaded to
a PC for further analysis.
The SMART STATUS TM feature provides the user of some immediate
information about the connection showing the ISDN Layer 1,2 and 3 status
in a detailed and clear way. Moreover, all B-channel relevant data like loop,
audio, called number, etc., are grouped in a specific page.
The tests dealing with the call, BER, X.25, loop-box, automatic check of the
access, help and lead the technician to a correct installation and a quick
troubleshooting.
The two hardware options (WT2071 and D1029) enrich the capabilities of
the user as they offer him further tests and simulations concerning the S/T
bus cabling and the check of the Terminal Equipment in standard and
emergency mode.
