Access security gateway
Access security gateway is an authentication interface used to secure the system
administration and maintenance ports and/or logins on the system. Access
security gateway employs a challenge/response protocol to confirm the validity of
a user and reduce the opportunity for unauthorized access.
Successful authentication is accomplished when the feature communicates with a
compatible key. The challenge/response negotiation is initiated once an RS-232
session is established and a valid system login ID has been supplied by a user. The
authentication transaction consists of a challenge, issued by the system and based
on the login ID supplied by the user, followed by receipt of the expected response,
which is supplied by the user.
Alternate facility restriction levels
This feature allows Avaya™ Communication Manager to adjust facility restriction
levels or authorization codes for lines or trunks. Each line or trunk is normally
assigned a facility restriction level. With this feature, alternate facility restriction
levels are also assigned. Attendants can change to the alternates, thus changing
access to lines and trunks.
