0x3487 Call awarded and being delivered in an established chan-
nel[#3487]
The user has been awarded the incoming call, which is being
connected to a channel already established to that user for
similar calls.
0x3491 User busy[#3491]
This message appears when the user called has indicated the
inability to accept another call. The user’s equipment is com-
patible with call, however.
0x3492 No user responding[#3492]
A user has not responded to a call set-up message with an
alert or connect indication within the prescribed time.
0x3493 No answer from user (user alerted)[#3493]
A user has provided an alert indication, but no connect indica-
tion within the prescribed time. This message is not normally
generated by ETS 300 102-1 procedures but may be generated
by internal network timers.
0x3495 Call rejected[#3495]
The equipment sending this message does not accept the call,
although it is neither busy nor incompatible.
0x3496 Number changed[#3496]
This message is returned to a caller when the number dialed
no longer exists. The new number may optionally be included
in the diagnostics field. If a network does not support his fea-
ture, message 0x3481 is returned.
0x349B Destination out of order[#349B]
The remote system dialed by the user cannot be reached be-
cause the interface is not working correctly. The phrase ‚out of
order‘ indicates that a signaling message could not be trans-
mitted to the remote user. Possible causes include: a physical
layer or data link failure at the remote station, user equipment
offline, etc.
0x349C Invalid number format[#349C]
This message indicates that the party dialed cannot be
reached because the number dialed is either incomplete or
has an invalid format.
