4. Detailed operating mode – User interface
In local mode, the unit is operated thanks to a keyboard and display on the front panel. The display is an
alphanumeric backlit LCD with two 20-character lines.
Operating from the keyboard can be protected by a password (8 digits maximum). In such case, the
password must be entered to start a session and get access to the user menus. The password can be
changed or deleted by the user.
4.1. Main operation modes
There are two parameters which have a major impact on the operation of the unit and on the user
interface.
First, the unit features three transmission modes: transmission over Ethernet/IP, “leased line” mode, and
transmission over the ISDN.
In comparison with the permanent leased line connection, IP and ISDN modes are “dial up” modes and
bring a number of additional parameters to be controlled:
•
dial number and/or full SIP URI for the destination of a call;
•
call set up and control;
•
device SIP registration data, or local ISDN number and sub-address;
•
miscellaneous network operation parameters.
The status display is slightly different in order to recall the transmission mode currently in use.
Second, in the leased line mode the unit can be operated either as a normal “single codec”, or as a “dual
codec” capable to transmit two independent 7 kHz bandwidth audio channels. This aspect has a big
influence on the way the device is installed, set up and monitored.
In the following, the main operation modes are shortly designated as: “IP mode”, “ISDN mode” or “LL
mode” (for leased line mode), and “Single codec” or “Dual codec”.
4.2. Equipment start-up
During start-up, the unit displays temporary messages. This initialisation lasts around one minute. Then
the main menu is displayed.
At this stage, if the configuration includes a non-blank password, the keypad is locked and the password
must be entered in order to access the menus: just enter the password (1 to 8 numbers), and the unit is
unlocked as soon as the last digit is entered. On factory setting or after erasure of the unit memory, the
password is blank so this step is skipped.
4.3. Description of the keyboard
Please refer to the description in 3.2.1 above(Front panel, LCD and basic control keypad).
