Channel Parameters

The Channel Parameters define the DTMF, Fax and Modem transfer modes. See
Appendix D: Fax and Modem Transport Modes
and Modem transfer modes; see
for detailed description on DTMF transport modes.
Note that the Default Channel Parameters are applied to all VCX V7122 channels.
In Table 30, parameters in brackets are the format in the Embedded Web Server

Valid Range and Description
131072 = Clears the call on reception of Q.931 Status with incompatible state.
Otherwise, (default) no action is taken.
Note: To configure the gateway to support several 'ISDNIBehavior' features,
summarize the individual feature values. For example to support both '512' and '2048'
features, set 'ISDNIBehavior = 2560'.
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 1–15 and 17–31. The D-channel is identified as channel-id #16 and
carried into the timeslot #16.
In newer QSIG standards, the channel-id range is 1–30, but the timeslot range is still
1–15 and 17–31. 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 1–15 and 17–31. 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

Same as the description for parameter 'ISDNInCallsBehavior' for a specific trunk ID
(x = 0–7)
Same as the description for parameter 'ISDNOutCallsBehavior' for a specific trunk ID
