Table 6-6: E1/T1/J1 Configuration Parameters (continues on pages 122 to 127)

ini File Field Name	Valid Range and Description
Web Parameter Name*
ISDNNFASInterfaceID_x	Defines a different Interface ID for each T1 trunk.
[NFAS Interface ID]	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	Defines CAS protocol for each Trunk ID (x = 0 to 7) from a list of protocols defined by
[CAS Table]	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	CAS file name (such as "E_M_WinkTable.dat") defines the CAS protocol. It is
CASFileName_1	possible to define up to 8 different CAS files by repeating the “CASFileName”
CASFileName_7	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	Range 0x0 to 0xF
[Idle ABCD Pattern]	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	Range 0x00 to 0xFF
[Idle PCM Pattern]	Default = -1 (default pattern = 0xFF for ∝-Law, 0x55 for A-law
	PCM Pattern to be applied to E1/T1 timeslot (B-channel) when the channel is idle.
LineBuildOut.Loss	0 = 0 dB (default)
[Line Build Out Loss]	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.
