Channel Parameters

The Channel Parameters define the DTMF, fax and modem transfer modes. See

The Default Channel Parameters are applied to all the gateway's channels.
V7122 Gateway User Guide
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 (for example, 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 IP Tel 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
