interface
type

standard has been detected.
rs449 A cable conforming to the RS449
standard has been detected.
rs422 A cable conforming to the RS422
standard has been detected.
rs423-v24 A cable is attached, but the connector
cannot distinguish whether it conforms
to RS423 or V.24 standards.
v28 A cable conforming to any of the CCITT
V.24, CCITT V.28, IS2110, or EIA-232-D
standards has been detected.
v35 A cable conforming to the V.35
standard has been detected.
x.21 A cable conforming to the X.21
standard has been detected.
previous Previous type of cable detected.
interface
type
no cable No cable was attached to the
interface.
unknown A cable was attached, but its type was
unknown.
o cable fault
Generated each time the communications cable is detected as
missing or invalid. Arguments (The call reference argument is present
only if the characteristic connection type is switched.):
call The call reference number of the call that was
reference disconnected because of the fault.
previous Type of cable that was connected before the error
interface was detected.
type
loopback A loopback connector.
null Modem A null modem cable.
rs232c A cable conforming to the RS-232-C
standard.
rs422 A cable conforming to the RS422
standard.
rs423-v24 A cable is attached, but the connector
cannot distinguish whether it conforms
to RS423 or V.24 standards.
rs449 A cable conforming to the RS449
standard.
unknown A cable was connected but its type was
unknown.
v28 A cable conforming to any of the CCITT
V.24, CCITT V.28, IS2110, or EIA-232-D
standards.
v35 A cable conforming to the V.35
standard.
x.21 A cable conforming to the X.21
standard.
reason Reason that caused the event to occur.
invalid A cable is attached but it is not one
cable of those recognized
no cable No cable can be detected
o clock loss
Generated each time a loss of the transmit or receive clock is
detected. Once this event occurs, the value of the interface state
attribute changes to pending dte ready.
o dce not ready
Generated each time a dce not ready condition is detected. Once
this event occurs, the value of the interface state attribute
changes to dte ready. This event is not supported if the
characteristic modem control is none.
o device error
A potential device error has been detected. This may be a
temporary condition that means the device can continue to be used.
Argument:
reason Reason for the failure. This is device specific.
o framing error
Generated each time an asynchronous framing error occurs.
o incoming call failed
Generated each time an incoming call is detected but the
connection fails to complete. This event is supported only if
the characteristic connection type is switched. Arguments:
call Call Reference of the call that failed to connect.
reference
reason Reason for the failure to complete the connection.
initial hold The time set by the characteristic
time expired initial hold timer has expired.
line The line has been disabled.
disabled
line failure There has been a communications
failure.
local The entity has disconnected the line.
disconnect
no call There is no client assigned to handle
control the call.
client
remote or The remote system has disconnected the
network line
disconnect
remote test The remote system is in test mode.
active
o loss of carrier
Generated each time the carrier frequency is lost while receiving
data. This event is not supported if the characteristic modem
control is none.
o outgoing call failed
Generated each time an attempt to complete an outgoing call fails.
This event is supported only if the characteristic connection type
is switched. Arguments:
Additional Any extra information on the call failure above that
information given in other arguments.
call Call reference of the call that failed.
reference
dial Dialing sequence used to make the call.
sequence
reason Reason that the call could not be completed.
call The call attempt occurred at the same
collision time as an incoming call was received.
call The call initiation failed.
initiation
failed
call not The remote system did not answer
answered the call within the time set by
the characteristic successful call
indication timer.
incoming An incoming call has already been
call answered.
answered
line The line is disabled.
disabled
line failure There has been a communications line
failure.
local The local system has disconnected the
disconnect line.
remote or The remote system has disconnected the
network line.
disconnect
remote test The remote system is in test mode.
active
o rate fallback
Generated each time the DCE indicates that it is changing from the
high data rate (as indicated by the speed characteristic) to the
low data rate (as indicated by the alternate speed characteristic.
This can occur if there is excessive noise when operating at the
high data rate. This event is supported only when the modem has a
rate selection capability.
o test indication
Generated each time the remote system tests the DCE. When this
event occurs, the value of the interface state attribute changes
to dte ready. This event is not supported id the characteristic
modem control is none.
o transmit enable timeout
Generated whenever the time to assert the clear to send signal
(after receiving the request to send signal) is greater that that
specified in the maximum enable transmit timer characteristic.
This event is not supported id the characteristic modem control is
none.
