Wink Start & Delay Dial Signaling

Outgoing Call Processing

During an outgoing call, the host receives an L3L4mPROGRESS in response to the L4L3mCALL_REQUEST to start the call. The host then receives an L3L4mSEIZE_COMP message if send_seize_comp_ event = 1 in the IISDN_ROBBED_BIT_DATA structure. This message is sent when the module detects a wink from the network, indicating the network is ready to receive digits. After the digits are transmitted, 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 26 shows how the module makes an outgoing call over a wink start or delay dial trunk.
