Async PAD Service Signals
Transmission of PAD service signals is determined by async PAD profile
parameter 6.
*
(Asterisk) – is normally the PAD prompt character.
“nnnnn” COM
– means that a virtual circuit has been established with a subscriber
whose ID is
“nnnnn.”
ALREADY CONNECTED
– indicates there is already a VC set up, so another call cannot
be made until the current call is cleared.
AUTOCALL INITIATED BY SUBSCRIBER “nnnmm”
– is self-explanatory.
AUTOCALL RETRIES EXHAUSTED-RETURN TO COMMAND STATE
– means that the
autocall retry timer has expired.
CALL CLEARED
– indicates that the call is being cleared.
CALL TIMED OUT
– is displayed when the network does not respond to a virtual circuit
call setup request within a certain time.
CLR (cause) (cause code) (diagnostic code)
– is displayed when the call is cleared.
Some common causes and codes are listed in Appendix D.
CLR CONF
– confirms the clearing of a call.
DISCONNECT TIMER EXPIRED
– indicates that the inactivity timer on the port has
expired.
ERR
– is a response to an invalid command.
ERR NC
– indicates a network congestion error.
FRAMING ERROR
– indicates that the port is not finding the stop bit at the end of the
character bits. This can be due to noise or a mismatch in such parameters as speed,
bits/character, or stop bits between the port and its connected device.
LINE DISCONNECTED
– indicates that modem signals on the port were dropped to
effect a physical disconnection.
login
– is a request to enter a subscriber ID.
LOGIN ACC
– indicates that login was successful and the user is now connected to the
network.
LOGIN REJ
– indicates that login was unsuccessful.
LOGOUT ACC
– is displayed when the PAD accepts a logout command.
LOGOUT REJ
– is displayed when the user attempts to log out, but either the Port
record was not configured to require login, or a VC on this port has not yet been
cleared.
