Network Connection
This apparatus is suitable for connection for direct 2 wire connection to the
PSTN and indirect 2 wire connection to the PSTN via compatible extensions
on a PABX system.
Facilities
The WC21 Controller's modem has been approved for use with the following
facilities:
• Signalling to the PSTN using DTMF signalling only
• Auto-answering
• Auto-call clearing
• Data modem
The modem should be set up for blind dialling (e.g., dial after delay, no dial tone
detection).
Any other usage will invalidate the approval of the apparatus if as a result it
then ceases to conform with the standards against which approval was gained.
Connection Methods
This apparatus is designed for connection to the PSTN using a modular jack
connection (RJ 11).
Connection to national networks in the EU may require an adapter compatible
with the national network.
CTR21 Type Approval
Annex II - Type Approval
The equipment has been approved in accordance with Council Decision 98/
482/EC for paneuropean single terminal connection to the Public Switched Tele-
phone Network (PSTN). However, due to differences between the individual PSTNs
provided in different countries, the approval does not, of itself, give an uncondi-
tional assurance of successful operation on every PSTN network termination
point.
In the event of problems, you should contact your equipment supplier in the
first instance.
