*
0 = Disable CAS relay (default).
1 = Enable CAS relay mode using RFC 2833.
The CAS relay mode can be used with the TDM tunneling feature to enable tunneling
over IP for both voice and CAS signaling bearers.
0 = x-channel header is not used (default).
1 = x-channel header is generated, with trunk/B-channel information.
The header provides information on the E1/T1 physical trunk/B-channel on which the
call is received or placed. For example "x-channel: DS/DS1-5/22". This header is
generated by the Mediant 2000 and is sent in the following messages: INVITE and
183/180/200OK responses.
This parameter enables to add an optional Information Element data (in hex format) to
ISDN SETUP message.
For example: to add the following IE: "0x20,0x02,0x00,0xe1", define: "AddIEinSetup =
200200e1".
Note: This IE is sent from the Trunk Group IDs defined by the parameter 'SendIEonTG'.
A list of Trunk Group IDs (up to 50 characters) from where the optional ISDN IE,
defined by the parameter 'AddIEinSetup', is sent.
For example: "SendIEonTG = 1,2,4,10,12,6".
Overrides the T310 timer for the DMS-100 ISDN variant.
T310 defines the timeout between the reception of Proceeding message and the
reception of Alert / Connect message.
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).
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.
Applicable only to Japan NTT PRI variant (ProtocolType = 16).
Note: This timer is also affected by the parameter 'PSTNAlertTimeout'.
