Table 3-54: Digital Gateway Parameters Description
Parameter Description
B-channel Negotiation
[BchannelNegotiation]
Determines the ISDN B-Channel negotiation mode.
 [0] Preferred
 [1] Exclusive (default)
 [2] Any
Notes:
 Applicable only to ISDN protocols.
 For some ISDN variants, when 'Any' (2) is selected, the SETUP
message does not include the Channel Identification IE.
 The 'Any' (2) option is applicable only if the parameter 'ISDN
Termination Side' is set to 'Use side' (refer to ''Configuring the
Trunk Settings'' on page 96).
Swap Redirect and Called
Numbers
[SwapRedirectNumber]
 [0] No = Don't change numbers (default).
 [1] Yes = Incoming ISDN call that includes a redirect number
(sometimes referred to as 'original called number') uses the
redirect number instead of the called number.
MFC R2 Category
[R2Category]
Determines the tone for MFC R2 Calling Party Category (CPC).
The parameter provides information on the calling party such as
National or International call, Operator or Subscriber and
Subscriber priority.
The value range is 1 to 15 (defining one of the MFC R2 tones).
The default value is 1.
Disconnect Call on Detection of
Busy Tone
[DisconnectOnBusyTone]
Determines whether a call is disconnected upon detection of a
busy tone.
 [0] Disable = Do not disconnect call on detection of busy tone.
 [1] Enable = Disconnect call on detection of busy tone (default).
Note: This parameter is applicable only to CAS protocols. For
ISDN, use the parameter ISDNDisconnectOnBusyTone.
Enable TDM Tunneling
[EnableTDMoverIP]
Enables TDM tunneling.
 [0] Disable = Disabled (default).
 [1] Enable = TDM Tunneling is enabled.
When TDM Tunneling is enabled, the originating device
automatically initiates SIP calls from all enabled B-channels
pertaining to E1/T1/J1 spans that are configured with the
'Transparent' protocol. The called number of each call is the
internal phone number of the B-channel from where the call
originates. The 'IP to Trunk Group' routing table is used to define
the destination IP address of the terminating device. The
terminating device automatically answers these calls if its E1/T1
protocol is set to 'Transparent' (ProtocolType = 5).
