Valid Range and Description
16 = The gateway clears down the call if it receives a NOTIFY message
specifying ‘User-Suspended’. A NOTIFY (User-Suspended) message is used
by some networks (e.g., in Italy or Denmark) to indicate that the remote user
has cleared the call, especially in the case of a long distance voice call.
32 = Applies only to ETSI E1 lines (30B+D). Enables handling the differences
between the newer QSIG standard (ETS 300-172) and other ETSI-based
standards (ETS 300-102 and ETS 300-403) in the conversion of B-channel ID
values into timeslot values:
•
In ‘regular ETSI’ standards, the timeslot is identical to the B-channel ID
value, and the range for both is 1 to 15 and 17 to 31. The D-channel is
identified as channel-id #16 and carried into the timeslot #16.
•
In newer QSIG standards, the channel-id range is 1 to 30, but the timeslot
range is still 1 to 15 and 17 to 31. The D-channel is not identified as
channel-id #16, but is still carried into the timeslot #16.
When this bit is set, the channel ID #16 is considered as a valid B-channel ID,
but timeslot values are converted to reflect the range 1 to 15 and 17 to 31. This
is the new QSIG mode of operation. When this bit is not set (default), the
channel_id #16 is not allowed, as for all ETSI-like standards.
1024 = Numbering plan / type for T1 IPÆTel calling number are defined
according to the manipulation tables or according to RPID header (default).
Otherwise, the Plan / type for T1 calls are set according to the length of the
calling number
Same as the description for parameter ‘ISDNIBehavior’ for a specific trunk ID (x
= 0 to 7)
Same as the description for parameter ‘ISDNInCallsBehavior’ for a specific
trunk ID (x = 0 to 7)
Same as the description for parameter ‘ISDNOutCallsBehavior’ for a specific
trunk ID (x = 0 to 7)
Channel Parameters
The Channel Parameters define the DTMF, fax and modem transfer modes. Refer to
Section 8.3 on page 208 for a detailed description of Fax and Modem transfer modes; refer
to Section 8.2 on page 206 for detailed description on DTMF transport modes.
Note that the Default Channel Parameters are applied to all the gateway's channels.
