Immediate Start/Fixed Pause Signaling
November 2009 287
Outgoing Call Processing (Fixed Pause Mode)
During an outgoing call, the host receives an L3L4mPROGRESS in
response to the L4L3mCALL_REQUEST to start the call. The
module waits a period of time (determined by the fixed pause timer)
before sending digits. When the timer expires, the host receives an
L3L4mSEIZE_COMP message if send_seize_comp_event = 1 in the
IISDN_ROBBED_BIT_DATA structure. After transmitting digits,
the module waits for answer supervision from the network
(indicating the far end has gone off hook) or for an answer timer to
expire (if timed_answer_supervision = 1). When answer supervision
is received or the timer expires, the host receives an
L3L4mCONNECT indicating the call is connected.
Figure 30 shows how the module makes an outgoing call over a fixed
pause mode trunk.
