For DTE-initiated calls
A Data Terminal Equipment (DTE) device is a device that an operator uses, such as a computer
or a terminal. The following Answer > T3POS Options parameters enable you to configure
DTE-initiated calls:
T3POS T2 Maximum amount of time permitted between the SYN signals sent
from the DTE to the PAD.This timer applies to opening frames in
Local or Bin-Local mode. Normally, the PAD sends SYN signals to
the DTE at the interval specified by the T2 timer to indicate that an
idle link is still alive. However, if the DTE sends a SYN signal to the
PAD before the PAD sends one to the DTE, the T2 timer specifies the
period of time the PAD expects SYN signals from the DTE. If the PAD
does not receive two SYN signals within the interval specified by the
T2 timer, it tries to restore the link. Also called the SYN-to-SYN timer.
T3POS T3 Amount of time the PAD waits for an ENQ from the host. Also called
the ENQ handling timer.
T3POS T4 Amount of time the PAD waits for a SYN from the DTE while the
PAD is waiting for a response from the DTE. The SYN signal
indicates that the response from the DTE is being delayed and also
indicates that the link is still alive. Also called the Response Timer.
T3POS T5 Maximum idle time the PAD allows for a T3POS call. This timer is
similar to the VC inactivity timer in the X25/PAD. The T5 timer
applies to transparent and blind mode only; it is disabled in both Local
mode and Bin-Local mode. Also called the DLE, EOT timer.
T3POS T6 Maximum amount of time allowed between the time a dial-up
connection is established and the first character of an opening frame is
received. Also called the Frame Arrival timeout.
Parameter Specifies
Parameter Specifies
Direct Call X.121
Addr Default host’s X.121 address.
Method of Host Notif How the host is notified of the mode of the call.
PID Selection Which Protocol Identifier (PID) the PAD includes in the call request
packet it sends to the host.
ACK Suppression Whether the PAD sends an acknowledgment when it receives an
opening frame from the DTE and when it establishes a virtual call with
the host.
