Above the display of a DT730 or DT750 SIP MLT handset there is a button marked ‘Security’. This allows the handset to be ‘locked’ as and when the user requires it.
The Security button can be enabled or disabled on a per extension basis using the Protection Service option in Wizard – Advanced Items/VoIP/Extensions/DT700 Setup./DT700 Additional features/DT700 Security Button. (PRG15-05-24)
To enable the Security feature on the handset: -Press the Security button
The display shows ‘Security Lock?’ (for about 5 seconds) Press the ‘OK’ softkey within this time
The display changes and scrolls the screen with the text ‘Security lock’, the red light next to the Security button is also illuminated.
To disable the Security feature on the handset: -Press any button on the handset
The display changes and shows ‘Security lock will be released. Please input a password.’
Enter the password (default 0000) and press the ‘OK’ softkey.
The phone is now unlocked.
The password can be changed on a per handset basis using the following steps: -Press Menu
Dial 5 1 4 – Enter the old password (default 0000) Press the ‘Set’ softkey
Enter the new password Press the ‘Set’ softkey
Enter the new password again Press the ‘OK’ softkey
The display says ‘Complete’
Press the ‘OK’ softkey then ‘Back’ several times until the idle screen is displayed.
Security Lock Override
It is possible to enter three pre-programmed numbers into a SIP MLT so that if the Security Lock is enabled the phone can still be used to call emergency numbers.
If a trunk must be accessed to call the emergency number, the trunk access digit must be set as part of the emergency number programmed into the handset.
To call the emergency numbers the handset must be used, pressing the Speaker key will not allow the emergency numbers to be dialled.
Upto 32 digits can be entered in each of the Emergency Dial locations.
e.g.
If the emergency number to dial is 112 via a trunk with a trunk access code of 9, the number programmed into the handset must be 9112.
Lift the handset and dial 9112, the call will proceed.
If the trunk access code is 0, the number programmed into the handset must be 0112.
Lift the handset and dial 0112, the call will proceed.
Once the Emercency number has been called the Security Lock is switched off until it is enabled again by the user.

LLDP
Description
Link Layer Discovery Protocol (LLDP) is used to transmit and receive information about neighboring network devices and IP telephones. Some SIP MLT settings can be automatically specified according to the LLDP data received from the network switch.
LLDP operates at layer 2 so the IP address of the terminal does not need to be specified until after the LLDP operation has completed.
LLDP uses IP Multicast to transmit/receive information so this must be taken into account on the customer’s network.
LLDP Standards
The supported standards are:
IEEE802.1AB:2005
ANSI/TIA-1057 LLDP-MED (LLDP for media endpoint discovery).
The device class is “Endpoint Class III”
Requirements
The SIP MLT must have firmware V4.0.0.0 or later to use the LLDP feature.
The SV8100 should have V4.0 software or later to use the LLDP feature.
The SIP MLT must be factory defaulted after the firmware upgrade to use the LLDP feature.
The network switch must support LLDP and be configured accordingly.
The network switch configuration varies depending upon the manufacturer and model. Consult the network administrator/maintainer for further information.
If the LLDP information becomes unavailable from the network the terminal will continue to operate unless it is rebooted. It will then use the settings from the terminal’s own configuration rather than the LLDP settings.
