Placing Data Calls From A Voice Terminal 2 - 7 - AT&T SYSTEM 25 Manual

Placing Data Calls from a Voice Terminal
This feature applies to multiline voice terminals only.
This feature allows multiline voice terminal users to originate or answer a call at their voice
terminals and then establish a data connection by transferring the call to a data terminal.
Data terminal calls can be set up from a multiline voice terminal with a DATA button. The
DATA button is associated by Data Dial Code (DDC) with a specific digital data endpoint.
The voice terminal must have a separate DATA button for each data terminal it is to
communicate with.
A multiline user, by going off-hook and pressing an idle DATA button, may indicate that a
data call will be attempted. This reserves the associated data port and a modem pool
conversion resource, and is recommended when the data call is a trunk call. After a call has
been established, invoking this feature transfers the call to the associated data terminal.
Calls to busy data ports can be queued, but a call requiring a pooled modem cannot be
queued. For more information about data calls, see Section 4, "Data Terminal Features. "
