Approval Type
This apparatus is declared under the RTTE. For details of the declaration of conformity to type,
please refer to Appendix 6
Usage and type
The 75 Ohm E1 card is designed for use connected to the Public Switched Telephone Network
(PSTN) via a 2048 Kbps digital service using Channel Associated Signaling (CAS) of the type
provided by:
BT in the BT Callstream service and defined in SIN 204 and SIN 205
Mercury Communications Plc and defined in MCL document SS5002
•
For use connected to a 2048 Kbps Integrated Services Digital Network (primary rate ISDN)
with DASS-2 signaling.
•
For use connected to a private circuit using the CCITT G.703 interface at 2048 Kbps in this
case the signaling is not specified, and for example includes DPNSS signaling.
The 120 Ohm E1 card described here 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 or
planned.
