DATA TERMINAL DIALING

Description

When the user makes a data call from a data terminal, voice terminal dialing and call progress tones are replaced by keyboard dialing and call progress messages. The message “DIAL:” prompts the user to enter the called number from the keyboard, and “RINGING” or “DIALING . . . COMPLETED” informs the user that the dialed number is being called.

Table 2-Hprovides a list of the call progress messages.

Note: The following dialing procedures assume that “Command Mode” is active. Refer to the subsection on “Expert Mode” for an alternative method of dialing.

Dialed Characters:

In addition to digits and the “#” and “*” characters on the touch-tone pad, the dialed number may contain the following special characters:

●The characters “(” “)” “ - ” and SPACE may be used to improve legibility. These characters are ignored.

●The “%” or “,” characters may be used to cause a 1.5-second pause in dialing.

Multiple pause characters can be used to produce longer pauses.

●The “$” (mark) character indicates that the remaining digits are for end-to-end signaling.

●UNDERSCORE or BACKSPACE characters may be used to correct previously typed characters on the same line.

●The “@” character may be used to delete the entire line and start over with a new DIAL: prompt.

Each line of dialing information may contain up to 27 characters. Note that all of the dialing information, including pauses and ignored characters, must be typed on a single line following the DIAL: prompt and terminated by Return.

Dialing Correction:

The backspace character (BS key or Ctrl-H keys) or underscore (“_’”) may be used to cancel the previously entered character. More than one entered character may be deleted by using multiple backspace or underscore characters. The “G” character may be used to delete the entire line of entered characters.

Pause:
To assist the completion	of off-premises	calls, the pause characters “%” or “,” may be used.
A pause character may be used to help		ensure the receipt of dial tone before continuing to
dial . Each “%” or “,”	causes a fixed	delay of one and one-half (1.5) seconds. Pause

characters may be used consecutively if a longer pause is required. Note that System 25 cannot detect tones, such as a second dial tone for end-to-end signaling.
