4. The registration data by Automatic Login method (MAC address authentication) can be backed up in
the flash ROM of the MP by MAT operation or automatic system data back up at a designated time.
Therefore, the installation engineer does not have to re-register the IP Enabled D
term when the system
reset should occur. The registration data by Login method (with password protected) cannot be
backed up.
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 D term is registered in the 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.
The encryption algorithm can be assigned on a system-wide basis by system programming (no
encryption is also available.).
2. The encryption is available in both Login method (with password protected) and Automatic Login
method (MAC address authentication).
3. Up to 8-digit password can be assigned by system programming. 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. 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 D
term , and cannot be assigned to
IP ports of IP trunks and IPELC. The VLAN assignment to the IP Enabled D term is provided by
Configuration Mode.
