• CHAP: Challenge Handshake Authentication Protocol as in RFC
1994. It involves a three-way handshake. In this, the test set
sends a challenge containing its user name. The server sends
a response with a specific identifier expected for this transac-
tion. The test set then accepts or rejects this response. Once
done, the handshake is complete and data may be sent.
• AUTO: Use this recommended setting to automatically detect
the authentication type requested by the ISP.
• NONE: Available for PPPoA, no authentication is required.
VPI
Range: 1 to 255 (default 8)
Along with the VCI, this identifies the next destination of a cell
as it moves through a series of ATM switches to its destination.
It is typically assigned by the service provider.
VCI
Range: 1 to 65535 (default is 35)
Along with the VPI, this identifies the next destination of a cell
as it moves through a series of ATM switches to its destination.
It is typically assigned by the service provider.
LOCAL IP (not in DHCP or DYNAMIC IP)
Specify the IP address of the circuit to be tested.
GATEWAY (LLC-BRG only)
Specify the gateway address. A gateway is a device that con-
nects dissimilar networks and passes information between them.
In TCP/IP, the default gateway address is the address where the
Internet Protocol sends packets destined for remote networks,
unless a different route is configured.
DNS SERVER
Options: NONE (F1), MANUAL (F2), AUTO, only for LLC-BRG
DHCP and PPPoE, PPPoA modes (F3)
The Domain Name System Server translates IP addresses into
domain names and vice versa. DNS allows you to reference
domain names instead of their actual numerical IP address. I.e.,
www.VeEXtelecom.com translates to 216.102.182.
• NONE: No domain name server, is used. The PING trace route,
and web access tests will only use an IP address.
• MANUAL: Manually enter the IP address of the DNS server.
Note that at the time of connection the test set will verify the
validity of the DNS server IP address.
• AUTO: This will automatically obtain the DNS server IP ad-
dress upon connection to the ISP.
