CHAP authentication is more secure than PAP authentication.

Login Name

The login name is given to you by your Internet service provider and is used as
the username for CHAP/PAP authentication.
Password
Enter the password exactly as given to you by your service provider. Passwords
are case sensitive. For example, the password cisco is not the same as Cisco.

Reenter Password

Reenter the same password that you entered in the previous box.
SPID Details
Some service providers use Service Provider ID numbers (SPIDs) to define the
services subscribed to by the ISDN device that is accessing the ISDN service
provider. The service provider assigns the ISDN device one or more S PIDs when
you first subscribe to the service. If you are using a service provider that requires
SPIDs, your ISDN device cannot place or receive calls until it sends a valid,
assigned SPID to the service provider when accessing the switch to initialize the
connection.
Currently, only the DMS-100 and NI switch types require SPIDs. The AT&T
5ESS switch type may support a SPID, but we recommend that you set up that
ISDN service without SPIDs. In addition, SPIDs have significance at the local
access ISDN interface only. Remote routers never receive the SPID.
A SPID is usually a seven-digit telephone number with some optional numbers.
However, service providers may use different numbering schemes. For the
DMS-100 switch type, two SPIDs are assigned, one for each B channel.

SPID1

Enter the SPID to the first BRI B Channel provided to you by your ISP.
