example, if the source terminal is restricted to on-premises calls only, a call to an off-
premises destination terminal will be blocked.
Setting Up A Third-Party Call
To set up a call from the third-party data terminal, the user selects <Voice call> from the
entry-level Command Mode menu (see Figure 2-58). The user then enters the characters as
required to call the destination terminal. Calls may be completed as follows.
Note:
If a character is entered incorrectly, the ASCII character backspace (BS or
CTRL-H keys) or underscore (_) may be used to cancel a previously entered
character.
Calling a Destination Terminal (source terminal is NOT associated with the third-party data
terminal)
After the user has selected <Voice call> from the Command Mode menu, a DIAL: prompt is
displayed on the third-party data terminal.
The user has 15 seconds to begin entering the
digits to be dialed before being disconnected.
The format of the digits following the DIAL:
prompt is shown below:
DIAL: {Destination}F{Source}
The Destination number must include all digits required to call the destination terminal and
may contain facility access codes, Speed Dialing codes, and pauses ( ✶ ). An “F” may be
entered immediately following the Destination digits; this character is used to separate the
Destination number from the Source number. The Source number must be a Personal Dial
Code when the source is a voice terminal, or a Data Dial Code when the source is a data
terminal. Floating PDCs are not allowed.
If the user enters the Destination number but not the Source number, the system prompts as
indicated below:
FROM: {Source}
The user must then enter the Source number.
Calling a Destination Terminal (source terminal is associated with the third-party data
terminal)
Following the DIAL: prompt the user enters the Destination number only. (System 25 will
automatically select the associated PDC or DDC as the Source number.)
If the third-party data terminal is permitted to establish calls for any source terminal, the
format {Destination}F{Source}
must be used to set up calls for any terminal except the
associated source terminal.
