Parameter Description
Web/EMS: B-channel
Negotiation
CLI: b-ch-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:
NFAS Parameters
Note: These parameters are applicable to PRI interfaces.
Web: NFAS Group Number
EMS: Group Number
CLI: isdn-nfas-group-number
[NFASGroupNumber_x]
Defines the ISDN Non-Facility Associated Signaling (NFAS)
group number (NFAS member) per trunk.
[0] = (Default) Non-NFAS trunk.
[1] to [12] = NFAS group number.
Trunks that belong to the same NFAS group have the same
number. With NFAS, you can use a single D-channel to control
multiple PRI interfaces.
Notes:
For this parameter to take effect, a device reset is required.
This parameter is applicable only to T1 ISDN protocols.
The x in the ini file parameter denotes the trunk number,
where 0 is Trunk 1.
For more information on NFAS, see 'ISDN Non-Facility
Associated Signaling (NFAS)' on page 289.
Web/EMS: D-channel
Configuration
CLI: isdn-nfas-dchannel-type
[DChConfig_x]
Defines primary, backup (optional), and B-channels only, per
trunk.
[0] PRIMARY= (Default) Primary Trunk - contains a D-channel
that is used for signaling.
[1] BACKUP = Backup Trunk - contains a backup D-channel
that is used if the primary D-channel fails.
[2] NFAS = NFAS Trunk - contains only 24 B-channels,
without a signaling D-channel.
Notes:
This parameter is applicable only to T1 ISDN protocols.
The x in the ini file parameter denotes the trunk number,
where 0 is Trunk 1.
Web: NFAS Interface ID
EMS: ISDN NFAS Interface ID
CLI: isdn-nfas-interface-id
[ISDNNFASInterfaceID_x]
Defines a different Interface ID per T1 trunk.
The valid range is 0 to 100. The default interface ID equals the
trunk's ID.
Notes:
To set the NFAS interface ID, configure ISDNIBehavior_x to
include '512' feature per T1 trunk.
The x in the ini file parameter denotes the trunk number,
where 0 is Trunk 1.
