■The ISDN call type.
■The name or (any) ID required to login to the ISP router.
■The Password Authentication Protocol (PAP) or Challenge Handshake Authentication Protocol (CHAP) passwords required to login to the ISP router. It is essential that the ISP specifies which of these are used by their router.
Configuring a PPP Connection
A PPP connection can be most easily configured using the Quick Configuration facility of the unit.
1Enter QC IN to display the Connect To Another PPP IP Router screen.
2Type the name supplied by the ISP in the Name of your Internet Provider or remote site field. This field is for reference only.
3Type the ISDN number for the ISP the ISDN number of the remote unit you want to call field.
4Toggle the Call Type field using the Spacebar to match the ISDN call type specified by the ISP.
5If the unit LAN port has already been configured, then the IP Address of this unit’s LAN port field will contain that address.
■If the LAN port has not been configured, please refer to Chapter 3 for details on how to configure the unit as an IP router.
6If the unit LAN port has already been configured, then the IP Mask of this unit’s LAN port field will contain the subnet mask.
■If the LAN port has not been configured, please refer to Chapter 3 for details on how to configure the unit as an IP router.
It is good practise to configure the PPP connection over ISDN to use unnumbered links because this makes best use of available IP addresses and is simple to configure.
7To configure the PPP connection to the ISP to use unnumbered links, leave the following three fields set to UNNUMBERED:
■IP Address of this end of the ISDN link.
■IP Address of the remote end of the ISDN link.
■IP Mask of the ISDN link.
