incoming calls to the MultiVoice Gateway. If you need to disable incoming calls, contact your
carrier.
Note:
If you have not configured any CLID profiles, you can use a work-around instead of
contacting the carrier. Set Ethernet > Answer > ID Auth to Required. The MultiVoice Gateway
does not accept any incoming calls on any E1 line. The MultiVoice Gateway does not answer
the call (go off-hook), so the caller is not charged for the call.
For lines configured with a DPNSS switch type, you can make a test connection to another
DPNSS unit without using an intervening switch by setting Back-to-Back to Yes.
For more information about each parameter, see the MAX Reference Guide.
Understanding the line interface parameters
This section provides background information about the E1 line interface parameters. (For
complete information, see MAX Reference Guide.)
E1 signalling mode
An E1 line’s signalling mode (Sig Mode) is typically country-specific and can be NONE
(leased) or one of the following:
•
ISDN—ISDN signalling using the D channel. You must designate the 32nd channel of the
E1 line as the D channel.
•
DPNSS—The interface supports DPNSS or DASS 2 signalling.
•
R2—R2 signalling. This is the R2 signalling protocol specific by ITU-T Recommendation
Q.464 (1988) - (Signalling System R2) Signalling between the outgoing international R2
register and the last incoming R2 register.
•
Argentinian—A version of the R2 signalling protocol supported in Argentina.
•
Brazil—A version of the R2 signalling protocol supported in Brazil.
•
Czech—A version of the R2 signalling protocol supported in Czech Republic and
surrounding states.
•
Indian—A version of the R2 signalling protocol supported in India.
•
Korean—A version of the R2 signalling protocol supported in Korea.
•
Malaysian—A version of the R2 signalling protocol supported in Malaysia.
•
Metered—Metered R2 signalling protocol, for use in Brazil and South Africa.
•
Chinese—A version of the R2 signalling protocol supported in China.
Note:
The default bandwidth for data calls across R2 lines is 64 Kbps, so set Ethernet >
Connections > Any Connection profile > Telco Options > Force 56 to Yes in any Connection
profile That should use 56 Kbps over R2 lines.
Note:
R2 signalling and country-specific signalling options are not supported for MultiVoice
Gateways using the MAX 2000
Carrier switch type
Switch Type is the type of network switch providing ISDN service on an E1 PRI line. Like E1
signalling mode, Switch Type is typically a country-specific parameter.
