5. When the IP terminal with a call in progress has the LAN cable extracted or a power-off occurs and
restores, in this situation, “Double Assignment” is displayed on the LCD. When the terminal is
registered by Automatic Login method the terminal can be used automatically after about two
minutes. When the terminal is registered by Login method the station user can login from the same
terminal after about two minutes, or login from another terminal (Override).
6. Logout operation from the IP terminal registered in Automatic Login method should not be done in
the normal operation. If the logout occurs, re-registration is required.
7. The registration data by Automatic Login method can be saved from the MAT by designating the
area number 80 (normal system data saving operation does not save the registration data).
Service Conditions on Encryption in System Registration
1. When the IP Enabled Dterm is registered in the U NIVERGE NEAX 2000 IPS, the login code (station
number) and password entered from the terminal can be encrypted.
Login code: Proprietary algorithm
Password: Proprietary algorithm or MD5 algorithm
MD5 is an algorithm defined in RFC 1321 from the IETF.
Encryption algorithm can be assigned on a system-wide basis (no encryption is also available).
2. Encryption is available for Login method (password protected) and Automatic Login method (MAC
address authentication).
3. Up to 8-digit password can be assigned. 0-9, A and B can be used as a password.
4. When the password is not assigned, the registration is not allowed and “Unauthorized” is
displayed on the terminal.
5. When the encrypted password is manipulated in the network, the registration is not allowed and
“Unregistered” is displayed on the terminal.
Service Conditions on VLAN
1. U NIVERGE NEAX 2000 IPS supports VLAN based on IEEE 802.1Q (Tag VLAN).
2. VLAN can be assigned to IP port(s) of MP, IP-PAD and IP Enabled Dterm, and cannot be assigned
to IP ports of IP trunks and IPELC. The VLAN assignment to the IP Enabled Dterm is provided by
Configuration Mode.
3. One IP port can have one VLAN ID. Multiple VLAN IDs cannot be assigned to the same IP port.
4. VLAN ID can be assigned from 1 to 4094. VLAN ID = 0 is handled as Null VLAN ID and is effective
to assign priority only.
5. Switching hub must support VLAN. If the switching hub does not support VLAN, the VLAN function
is not effective even when the system data of the U NIVERGE NEAX 2000 IPS is assigned.
