Table 5-3. Remote Node Profile Menu Fields for Leased Line Applications (continued)

Field	Description	Option
Outgoing: Authen	This field sets the authentication protocol used for	CHAP/PAP
	outgoing calls.
(*for backup line only)	Your Prestige supports two authentication protocols:	CHAP
	PAP (Password Authentication Protocol) and CHAP	PAP
	(Challenge Handshake Authentication Protocol).
	• PAP sends the user name and password in plain
	text.
	• CHAP scrambles the password before it is sent
	over the wire.
	Generally speaking, CHAP is more secure than PAP;
	however, PAP is readily available on more platforms.
	The recommendation is to use CHAP whenever
	possible. Turning off the authentication is STRONGLY
	discouraged.
	Options for this field are:
	• CHAP/PAP - Your Prestige will try CHAP when	[CHAP/PAP]
	CHAP is requested by the Remote Node or PAP
	when PAP is requested by the Remote Node.

•CHAP - use CHAP only.

•PAP - use PAP only.
