Valid Range and Description
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 each T1 trunk.
CASTableIndex_x
[CAS Table] Defines CAS protocol for each Trunk ID (x = 0 to 7) from a list of protocols defined by
the "CASFileName_Y" parameter.
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 (such as "E_M_WinkTable.dat") defines the CAS protocol. It is
possible to define up to 8 different CAS files by repeating the “CASFileName”
parameter. Each CAS file can be associated with one or more of the gateway trunks
using "CASTableIndex_x" parameter.
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.
LineBuildOut.Loss
[Line Build Out Loss] 0 = 0 dB (default)
1 = -7.5 dB
2 = -15 dB
3 = -22.5 dB
Selects the line build out loss to be used for T1 trunks
N/A for E1 trunks.
ISDNRxOverlap
0 = Disabled (default).
1 = Enabled.
Any number bigger than one = Number of digits to receive.
Note 1:
If enabled the Mediant 2000 receives ISDN called number that is sent in the
"Overlap" mode.
Note 2:
The INVITE to IP is sent only after the number (including “Sending
Complete” Info Element) was fully received (in SETUP and/or subsequent INFO
Q.931 messages).
For detailed information on ISDN overlap dialing, refer to Section
8.3 on page 140 .
