	generated by the Mediant 2000 and is sent in the following messages: INVITE and

AddIEinSetup	This parameter enables to add an optional Information Element data (in hex format) to
[Add IE in SETUP]	ISDN SETUP message.

	200200e1”.
	Note: This IE is sent from the Trunk Group IDs defined by the parameter ‘SendIEonTG’.
SendIEonTG	A list of Trunk Group IDs (up to 50 characters) from where the optional ISDN IE,
[Trunk Groups to Send IE]	defined by the parameter ‘AddIEinSetup’, is sent.
	For example: "SendIEonTG = 1,2,4,10,12,6”.
ISDNDMSTimerT310	Overrides the T310 timer for the DMS-100 ISDN variant.
	T310 defines the timeout between the reception of Proceeding message and the

	The valid range is 10 to 30. The default value is 10 (seconds).
	Note: Applicable only to Nortel DMS and Nortel MERIDIAN PRI variants (ProtocolType
	= 14 and 35).
ISDNJapanNTTTimerT3JA	T3_JA timer (in seconds).
	This parameter overrides the internal PSTN T301 timeout on the Users Side (TE side).
	If an outgoing call from the Mediant 2000 to ISDN is not answered during this timeout,
	the call is released.
	The valid range is 10 to 240. The default value is 50.
