Wink Start & Delay Dial Signaling

The remaining settings are described in the context of incoming and outgoing calls in the subsections that follow. Brooktrout modules process calls in the same manner on both wink start and delay dial trunks.

Incoming Call Processing

During an incoming call, the host receives an L3L4mPRE_SEIZE message if send_preseize_event = 1 in the IISDN_ROBBED_BIT_ DATA structure. This message is sent when the module detects an incoming seizure (off hook). The module automatically responds to the seizure by sending a wink signal, indicating it is ready to receive digits. The maximum number of digits the module expects to receive must be specified in the max_incoming_digit_count field. The digits are reported to the host in an L3L4mSETUP_IND message. To answer the call, the host must issue an L4L3mCONNECT_ REQUEST message.

Figure 25 shows how a Brooktrout module processes an incoming call received over a wink start or delay dial trunk.
