Circuit Card Description and Installation
Outbound calls
The DAC supports two types of outbound data calls:
• point-to-point data calls
• calls sent through a modem without call origination capabilities
Hayes dialing does not provide for any alterations during call processing,
Ring Again, or Controlled Call Back Queueing (CCBQ) for example.
Consequently, if such variances occur during the call processing, the DAC
releases the call and notifies you with a NO CARRIER or BUSY result code.
Table 163 lists the command characters allowed for an outbound call.
Inbound calls
The DAC supports auto answer and manual answer capabilities. The
following commands give examples of both auto and manual answer
dialogues.
This dialogue session describes the sequence when the S0 register is set to
three. In this case, the DAC automatically answers the incoming call on the
third ring, and the session begins with the CONNECT message.
