Parameter Description
configure voip >
interface e1-t1 >
isdn-nfas-interface-
id
[ISDNNFASInterfaceID]
The valid range is 0 to 100. The default interface ID equals the
trunk's ID.
Note:
If you are modifying the parameter for an existing
(configured) trunk through the Web interface, you must
first stop the trunk.
To set the NFAS interface ID, configure ISDNIBehavior_x
to include '512' feature per T1 trunk.
The parameter is applicable only to T1 ISDN protocols.
For more information on NFAS, see ISDN Non-Facility
Associated Signaling (NFAS).
'D-channel Configuration'
configure voip >
interface e1-t1 >
isdn-nfas-dchannel-
type
[DChConfig]
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.
Note:
If you are modifying the parameter for an existing
(configured) trunk through the Web interface, you must
first stop the trunk.
The parameter is applicable only to T1 ISDN protocols.
For more information on NFAS, see ISDN Non-Facility

CASTableIndex_5 = 0
DialPlanFileName = 'DialPlan_USA.dat'
CASTrunkDialPlanName_5 = 'AT_T'
'CAS Table per Trunk'
configure voip >
interface e1-t1 >

CAS (E_M_ImmediateTable.dat) protocol:
