Configuring the WAN Interfaces
Configuring E1 lines
Carrier switch types for E1/PRI lines include:
• GloBanD—Q.931W GloBanD data service.
• NI-1—National IDSN-1.
• Net 5—Euro ISDN services in Belgium, the Netherlands, Switzerland, Sweden, Denmark,
and Singapore.
• Danish—Conforms to the Danish E1-TB91020, July 1991 specification. Is a variation of
Net5 PRI E1.
• DASS 2—U.K. only.
• ISLX—DPNSS switch type.
• ISDX—DPNSS switch type.
• Mercury—DPNSS switch type.
• Australian—Australia only.
• French—VN3 ISDN PRI.
•German—1TR6.
• CAS—New Zealand.
E1 framing
The physical layer of the E1 line uses a type of G.703 framing, which is the standard framing
mode used by some E1 ISDN providers and by DASS 2, or 2DS, a variant of G.703 required
by most European telecommunications providers.
Specifying digits received on an incoming R2 call
The Number Complete parameter specifies how many digits complete the number of an
incoming call using R2 signalling. You can specify end-of-pulsing to indicate that the
MultiVoice Gateway should keep on receiving digits until the caller stops sending them, or you
can specify a fixed number of digits (up to 10).
Group signalling
Group B signalling and Group II signalling specify the group signal to send before answering a
call.
Collecting Caller ID
The Caller ID parameter enables the MultiVoice Gateway to collect the ANI signals for
country-specific R2 signalling sets (i.e., Sig Mode=CZECH). This parameter must be enabled
(Caller ID=Yes) in order to support ANI authentication of MultiVoice users on networks
processing localized E1 R2 signals.
Required settings for DPNSS or DASS 2 switches
• L3 End and L2 End—Specify CCITT Layer 3 and CCITT Layer 2, respectively.
• NL value—Default value is 64.
• Loop Avoidance—Default value is 7.
