ini File Field Name
Web Parameter Name
Valid Range and Description
TraceLevel
[Trace Level]
Defines the trace level.
Valid options include:
0 = No trace (default)
1= Full ISDN trace
2 = Layer 3 ISDN trace
3 = Only ISDN Q.931 messages trace
4 = Layer 3 ISDN no duplication trace
FramingMethod
[Framing Method]
Selects the framing method to be used for E1/T1 spans.
For E1
0 = Multiframe with CRC4 (default, automatic mode, if CRC is identified in the
Rx, CRC is sent in Tx, otherwise no CRC).
a = Double frame
c = Multiframe with CRC4
For T1
0 or D = Extended super frame with CRC6 (default)
1 or B = Super frame D4, F12 (12-Frame multiframe)
A = F4 (4-Frame multiframe)
C = Extended super frame without CRC6
F = J1 - Japan (ESF with CRC6 and JT)
ISDN Configuratuion Parameters
TerminationSide
[ISDN Termination Side]
Selects the ISDN termination side. Applicable only to ISDN protocols.
0 = ISDN User Termination Side (TE) (default)
1 = ISDN Network Termination Side (NT)
Note: select ‘User Side’ when the PSTN or PBX side is configured as ‘Network
side’, and vice-versa. If you don’t know the gateway ISDN termination side,
choose ‘User Side’ and refer to the ‘Status & Diagnostics>Channel Status’
screen. If the D-channel alarm is indicated, choose ‘Network Side’.
NFASGroupNumber_x
[NFAS Group Number]
0 = Non NFAS trunk (default)
1 to 4 = NFAS group number
Indicates the NFAS group number (NFAS member) for the selected trunk.
‘x’ identifies the Trunk ID.
Trunks that belong to the same NFAS group have the same number.
With ISDN Non-Facility Associated Signaling you can use single D-channel to
control multiple PRI interfaces.
Applicable only to T1 ISDN protocols.
ISDNNFASInterfaceID_x
[NFAS Interface ID]
Defines a different Interface ID for each T1 trunk.
The valid range is 0 to 100.
The default interface ID equals to the trunk’s ID.
’x’ identifies the trunk ID.
Note: To set the NFAS interface ID, configure: ISDNIBehavior_x to include
‘512’ feature, per T1 trunk.
DChConfig_x
[D-channel Configuration]
0 = Primary Trunk (default)
1 = Backup Trunk
2 = NFAS Trunk
D-channel configuration parameter defines primary, backup (optional) and B-
channels only trunks.
’x’ identifies the Trunk ID.
Primary trunk contains D-channel that is used for signaling.
Backup trunk contains backup D-channel that is used if the primary D-channel
fails.
The other NFAS trunks contain only 24 B-channels, without a signaling D-
channel.
Note: Applicable only to T1 ISDN protocols.
