15.1 Clear Speed-Dialing and Call-Barring Tables
This command will erase all of the values in the global Speed-Dialing table and all of the values in the Call-
Barring (Toll-Restriction) tables. The speed-dialing numbers assigned to individual extensions are not
affected. This command also resets the individual extension Call-Barring passwords to their default value
(“111111”). (See the User’s Guide for more information about individual call barring.)
1. In the programming mode, enter 7875. Pause for the confirmation tone. Hang up or continue
programming.
15.2 Dial-Tone Detection
Specially equipped versions of the Phone Line Manager 16 x 4 can be programmed to detect that a dial tone
is present from the Central Office before a speed dial or redial operation will start sending the digits to the
Central Office. When this command is disabled (default condition), the Phone Line Manager 16 x 4 will
wait the amount of time set in the “Speed Dialing Delay Time” parameter before dialing the digits (see
Section 19.14).
Dial-Tone Detection will only operate on Phone Line Manager 16 x 4 units which contain the optional
dial-tone detection hardware.
To enable Dial-Tone Detection for Speed Dialing and Redialing:
1. At the System Manager’s extension, lift the handset and enter 7840. Pause for confirmation tone.
To disable Dial-Tone Detection and use the Speed-Dial Delay Time:
1. At the System Manager’s extension, lift the handset and enter 7841. Pause for confirmation tone.
