IP Line Description, Installation and Maintenance
If the PWD1 is changed and an EDD operation is not performed, the cards can
contain a mixture of old and new passwords. This could happen if a new card
is plugged in, an existing card reboots or loses and reestablishes its ELAN
subnet connection. Nortel recommends that an EED be performed when the
PWD1 password is changed on the Call Server. Performing an EDD ensures
that all cards have the new PWD1 user ID and password.
For more information on the PWD1 Level 1 password, see the “LD 17 Gate
Opener PWD (Password)” section in Software Input/Output: Administration
(553-3001-311).

IP Phone Installer Password

An IP Phone displays the node ID and Terminal Number (TN) of the IP Phone
for five seconds as the IP Phone boots up. IP Line 4.0 password protection
controls who can change the TN on the IP Phone. This feature is available on
the IP Phone 2001, IP Phone 2002, IP Phone 2004, IP Phone 2007, IP Audio
Conference Phone 2033, IP Softphone 2050, and MVC 2050. The IP Phone
Installer Password protection controls registration with a virtual line TN on
the Call Server.
Note: The IP Phone Installer Password can also be configured using the
CLI commands in Element Manager. See “Setting the IP Phone Installer
Password” on page 627.
Administrator IP Phone Installer Password
This feature adds basic IP Phone Installer Password protection on the IP
Phones to control registration with a virtual line TN on the Call Server. This
feature does not provide a user password or a Station Control Password for
IP Phones.
