Transfer To Data
Description
This feature allows multiline voice terminal users to originate or answer a call from their voice
terminals and then establish a data connection by transferring the call to a data terminal.
Note: Single-line voice terminals cannot be used to establish a data connection by trans-
ferring a call to a data endpoint.
(Refer also to the overview of the system’s data features provided in the “Data Services Overview”
description.)
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 digital data endpoint. A separate DATA button
must be provided for each data terminal that the voice terminal can transfer calls to.
The DATA button status LED provides status indications for the data endpoint:
● Dark—Data endpoint is idle
● Winking—Data endpoint is reserved
● Flashing—Data endpoint is being alerted to an incoming call
● Steadily Lighted—Data endpoint off-hook (busy).
The DATA button status LED will wink only when a voice terminal reserves a data endpoint by Data
Call Preindication.
Data Call Origination Using Transfer to Data
A voice terminal user, after calling a DDC or a PDC (to reach an analog data endpoint) receives
either answer tone or called party answer, respectively. The user then transfers the call to the
associated data terminal by pressing DATA and hanging up. The called party may also use Transfer
To Data to transfer the call to a data terminal, or may press the Data button on an associated
modem.
An inside call cannot be transferred via Transfer To Data until the far end answers.
If a handshake failure occurs after Transfer To Data, the data call will be disconnected and the data
terminal left in the idle (on-hook) state.
Note: Even if the associated data port is optioned for autobaud, the call will be set up at the
highest common speed that the calling and called data terminals are administered for,
independent of the current data terminal settings.
