A.12.6.4 ISDN Parameters
The ISDN parameters are described in the table below.
Table A-58: ISDN Parameters
Parameter Description
Web: ISDN Termination Side
EMS: Termination Side
[TerminationSide]
Determines the ISDN termination side.
 [0] User side = ISDN User Termination Equipment (TE) side
(default)
 [1] Network side = ISDN Network Termination (NT) side
Note: Select 'User side' when the PSTN or PBX side is
configured as 'Network side' and vice versa. If you don't know the
device's ISDN termination side, choose 'User side'. If the D-
channel alarm is indicated, choose 'Network Side'.
The BRI module supports the ITU-
T I.430 standard, which defines
the ISDN-BRI layer 1 specification. The BRI and PRI ports are
configured similarly, using this parameter. When an NT port is
active, it drives a 38-V line and sends an INFO1 signal (as
defined in ITU-T I.430 Table 4) on the data line to synchronize to
a TE port that might be connected to it. To stop the voltage and
the INFO1 signal on the line, stop the trunk using the Stop Trunk
button.
[TerminationSide_x]
Same as the description for parameter TerminationSide, but for a
specific trunk ID (where x denotes the Trunk ID and 0 is the first
Trunk).
BRI Layer 2 Mode
[BriLayer2Mode]
Determines whether Point-to-Point or Point-to-Multipoint mode for
BRI ports.
 [0] Point to Point (default)
 [1] Point to Multipoint = Must be configured for Network side.
Web/EMS: B-channel Negotiation
[BchannelNegotiation]
Determines the ISDN B-Channel negotiation mode.
 [0] Preferred.
 [1] Exclusive (default).
 [2] Any.
Notes:
 This parameter is applicable only to ISDN protocols.
 For some ISDN variants, when 'Any' (2) is selected, the Setup
message excludes the Channel Identification IE.

The Any' (2) option is applicable only if the following conditions
are met:

The parameter TerminationSide is set to 0 ('User side').

The PSTN protocol type (ProtocolType) is configured as
Euro ISDN.
NFAS Parameters
Note: These parameters are applicable to PRI interfaces.
Web: NFAS Group Number
EMS: Group Number
[NFASGroupNumber_x]
Defines the NFAS group number (NFAS member) for the
selected trunk, where x denotes the Trunk ID.
 0 = Non-NFAS trunk (default)
 1 to 12 = NFAS group number
Trunks that belong to the same NFAS group have the same
number.
With ISDN Non-Facility Associated Signaling you can use single
