ini File Field Name
Web Parameter Name
Valid Range and Description
TDMBusPSTNAutoClockRe
vertingEnable
[TDM Bus PSTN Auto Clock
Reverting]
Enables and disables the PSTN trunk auto-fallback reverting feature. If a trunk
with a higher priority than the current LocalReference is being synchronized, the
board LocalReference changes to the new trunk.
0 = disable (default).
1 = enable.
Note: The parameter is valid only in when the TDMBusPSTNAutoClockEnable
parameter is set to 1.
LineCode
[Line Code]
0 = use B8ZS line code (for T1 trunks only) default.
1 = use AMI line code.
2 = use HDB3 line code (for E1 trunks only).
Use to select B8ZS or AMI for T1 spans, and HDB3 or AMI for E1 spans.
LineCode_x
[Line Code]
Same as the description for parameter ‘LineCode’ for a specific trunk ID (x = 0
to 7).
BchannelNegotiation
[B-channel Negotiation]
Determines the ISDN B-Channel negotiation mode.
0 = Preferred
1 = Exclusive (default)
Applicable to ISDN protocols.
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 (0-7).
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.
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 (0-7).
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.
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 (0 to 7).
’x’ identifies the trunk ID (0-7)
Note: To set the NFAS interface ID, configure: ISDNIBehavior_x to include
‘512’ feature, per T1 trunk.
CASTableIndex_x
[CAS Table]
Defines CAS protocol for each trunk ID (x = 0 to 7) from a list of CAS protocols
defined by the parameter CASFileName_Y.
For example:
CASFileName_0 = 'E_M_WinkTable.dat'
CASFileName_1 = 'E_M_ImmediateTable.dat'
CASTableIndex_0 = 0
CASTableIndex_1 = 0
CASTableIndex_2 = 1
CASTableIndex_3 = 1
Trunks 0 and 1 use the E&M Winkstart CAS protocol, while trunks 2 and 3 use
the E&M Immediate Start CAS protocol.
