6.5.6 Checking abbreviated dialling keys
An abbreviated dialling key can be checked in the following call processing terminal statuses:
• idle status (handset is on-hook)
• after off-hook
• when a call is in progress
The abbreviated dialling key must be held down until the saved call number appears on the display (approx.1 second). The
message "No number" is displayed if there is no call number saved. The display switches back to the original display after
30 seconds (or by going on-hook).
6.5.7 Programming abbreviated dialling keys
Abbreviated dialling keys can be overwritten (by keypad entry) while they are displayed in the checking procedure (see
Chapter
6.5.6 "Checking abbreviated dialling keys" on page 150
6.5.8 Redial
The last call number dialled is shown on the display and signal transmission to the PLMN is started by pressing the redial
key after going off-hook. Call numbers are transferred to the redial memory during signal transmission.

6.5.9 Network call barring
The PLMN offers the user the option of barring special connections. This is activated by the user with a code and password
(see Chapter
6.4 "MMI features and user-defined settings" on page 143
• all outgoing connections
• all outgoing international connections
• all outgoing international connections that are not directed to the home PLMN country
• all incoming connections
• all incoming connections in the case of roaming outside the home PLMN country
6.5.10 Local call barring
As in the case of PLMN, special connections can be barred in the terminal. This is activated by the user with codes. To
distinguish this feature from network call barring, no signalling information is sent to the PLMN. As a result, this feature
can also be used when no connection to the PLMN can be set up.
The following connections can be barred:
• all outgoing connections
• all incoming connections
Note: local call barring features are not recognised by the network. They are locally set in the terminal.
