1-4 Getting to know your Prestige
SMT
The System Management Terminal (SMT) is a menu-driven interface to configure your Prestige using either
console port (through RS232 cable) connection or telnet (through LAN) connection. You can access the SMT
from either a VT100 compatible terminal or a terminal emulation program on a computer.
Logging and Tracing
♦
CDR (Call Detail Record) for assistance in analyzing and managing the telephone bill.
♦
Built-in message logging and packet tracing.
♦
UNIX syslog facility support.
RADIUS Support
RADIUS (Remote Authentication Dial-In User Service) is the most popular protocol for user authentication
on dial-up lines. RADIUS support allows you to use an external server for unlimited number of users and
helps in the centralized management of the users database.
PAP and CHAP Security
The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure than PAP; however, PAP is readily available on more
platforms.
CLID Support
CLID (Calling Line Identification) allows the Prestige to authenticate the caller before a call is answered,
thus saving the cost of a connection. The Prestige uses the caller ID in call setup message to match against
the CLID in database. (Note: The telephone company must support Caller ID for CLID authentication to
work on the Prestige.)
Call Back
The Callback feature allows the Prestige to disconnect a call and then call back when an authorized remote
user dials into the system. This prevents intruders from accessing your network and makes accounting easier
when you use the Prestige as a dial-in server.
