6.2.3.4.4 Security

In the remote access, the protocol used in the "data link" OSI layer is PPP (Point-to-Point
Protocol). The TCP/IP protocols are used respectively in the "transport" and "network" layers.
For each layer, Alcatel-Lucent OmniPCX Office Communication Server carries out an access
control.
Authentication
At the start of the connection (PPP), an account name (system masked) and password
(pbxk1064) are required. This account name is automatically generated by OMC. The
password is required by OMC to establish a direct connection (LAN) with Alcatel-Lucent
OmniPCX Office Communication Server. Any other authentication will be rejected.
Firewall

data packets received on this interface will be filtered according to the following rules:
