o cable detected Generated when a valid communication cable is detected following a cable fault event. Arguments: current Type of cable detected. interface type loopback A loopback connector has been detected. null modem A null modem has been detected. rs232c A cable conforming to the RS-232-C 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.
