USER’S MANUAL REV. 5 <strong>ISDN</strong> <strong>ANALYZER</strong> <strong>D1080</strong><br />
! For easier reference, this manual uses the following<br />
abbreviations for the measurement plugs:<br />
E1 for E1- 120W<br />
S- TO NT for S0- MONITOR/TE SIMUL<br />
S- TO TE for S0- TE TEST<br />
For plug pins, see APPENDIX C.<br />
3.3.1.1. Connection over primary access<br />
The instrument interface complies with ITU-T I.431, ETSI300 011<br />
Recom. with balanced 120Ω impedance. In case of connections to<br />
unbalanced 75Ω lines, use the adapter supplied.<br />
Use the plug marked as “E1” standard ISO8877 polarized for tests<br />
as <strong>ISDN</strong> terminal simulator (TE SIMULATOR or TE X.25<br />
SIMULATOR) or as monitor for protocol analysis on D channel.<br />
When testing a user terminal (TE TEST or X.25 TE TEST), connect<br />
to the tested terminal by means of crossed cable on the “E1”<br />
plug.<br />
3.3.1.2. Connection over basic access<br />
The instrument interfaces for the Basic Access comply with Recom.<br />
ITU-T I.430, ETSI300 012.<br />
In or<strong>de</strong>r to carry out tests on the “S0” interface as <strong>ISDN</strong> terminal<br />
simulator (TE SIMULATOR or X.25 TE SIMULATOR) or as monitor<br />
for protocol analysis on the D channel, use the ISO8877 plug<br />
