A point-to-point full duplex or simplex data circuit can be pre-defined at the
MIDAS Controller, and a unique identifier associated with it.

• This definition is used for establishing permanent circuits.
• The data circuit definitions are also used for automatic call initiation by

the customer equipment via RTS/DTR signal or alternately a CiM
Modem.

• This feature is useful for applications such as automatic circuit restoral

and congestion reduction.

• Figure 5-8 illustrates a sample data circuit details screen.
