Appendix C:
Approval details for UK and other EU countries
This section applies only to E1/T1 trunk interfaces configured for E1 operation.
Usage and type
A 75 ohm E1 trunk is designed
•
For use when connected to the Public Switched Telephone Network (PSTN) via a
2048 Kbps digital service using Channel Associated Signalling (CAS).
•
For use connected to a 2048 Kbps Integrated Services Digital Network (primary
rate ISDN) with DASS-2 signalling.
•
For use connected to a private circuit using the ITU G.703 interface at 2048 Kbps
in this case the signalling is not specified, and for example includes DPNSS
signalling.
A 120 ohm E1 trunk is principally designed
•
For use connected to a 2048 kb/s integrated services digital network (primary
rate ISDN) with ETS300-102 signalling, but other types of private circuit use are
also appropriate, and other signalling systems are available, for example QSIG or
ISUP (SS7).
