Regulatory Compliance Information and Safety
Australian Communications Authority Technical Standard 031
The following warning applies to voice interface cards.
Warning This equipment will be inoperable when main power fails.
European Commission
FXO voice interface cards have been approved to Common Technical Regulation
(CTR) 21 for pan-European single-terminal connection to the PSTN. However,
because of differences among the PSTNs in different countries, this approval does
not in itself give unconditional assurance of successful operation on every PSTN
network termination point. DTMF dialing is the default setting and is required for
compliance to CTR21. Where pulse dialing is required for network compatibility,
see the Pulse Dialing section for details.
In the event of problems, you should first contact your equipment supplier.
Call Progress Tone Settings
FXO voice interface cards are available in several versions with interfaces
intended for different geographical regions.
There are no hardware settings for connecting these voice interface cards to the
public switched telephone network. To comply with national regulatory
requirements, you must set call progress tones with the Cisco IOS cptone
command to the values shown in Table 1-10.
To set call progress tones for a voice port, enter the following commands in global
configuration mode:
Router(config)# voice-port slot-number/subunit-number/port
Router(config-voice-port)# cptone setting
