Considerations

Data Terminal Dialing allows users to place data calls from their terminals using the Data Terminal Dialing feature and allows users to review the options administered for their data ports.

Interactions

●End-To-End Signaling: (See above text)

●Modem Pooling: Data calls between analog and digital endpoints require that a conversion resource (TN758) be available. If one is not, the “NO MODEM” followed by “TRY AGAIN” message will be displayed.

●Speed Dialing: System Speed Dial codes can be dialed from data terminals.

Administration Requirements

Data Port: See the table of Permissible Data Port Options in the “Command Mode” feature description.

Hardware Requirements

TN726 Data Line CP to support each digital endpoint.

TN758 Pooled Modem CP to support data calls between digital and analog endpoints.
