Valid Range and Description
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.
Applicable only to T1 ISDN protocols.
Backup trunk is not supported for DMS PRI variants.
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)
To set the NFAS interface ID, configure: ISDNIBehavior_x to
include ‘512’ feature, per each 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.
CASFileName_0
CASFileName_1
CASFileName_7 CAS file name (e.g., ‘E_M_WinkTable.dat’) that defines the CAS protocol. It
is possible to define up to eight different CAS files by repeating this
parameter. Each CAS file can be associated with one or more of the
gateway trunks using the parameter CASTableIndex_x.
CASTablesNum 1 to 8. Indicates how many CAS protocol configurations files are loaded.
IdleABCDPattern
[Idle ABCD Pattern]
Range 0x0 to 0xF
Default = -1 (default pattern = 0000)
ABCD (CAS) Pattern to be applied to CAS signaling bus when the channel
is idle. This is only relevant when using PSTN interface with CAS protocols.
Set to -1 for default.
IdlePCMPattern
[Idle PCM Pattern]
Range 0x00 to 0xFF
Default = -1 (default pattern = 0xFF for
μ
-Law, 0x55 for A-law
PCM Pattern to be applied to E1/T1 timeslot (B-channel) when the channel
is idle.
