ONNECTIONS

■

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.

A PPP connection can be most easily configured using the Quick 
Configuration facility of the unit.

1 Enter 

 

 to display the Connect To Another PPP IP Router screen.

2 Type the name supplied by the ISP in the Name of your Internet 

Provider or remote site field. This field is for reference only.

3 Type the ISDN number for the ISP the ISDN number of the remote 

unit you want to call field.

4 Toggle the Call Type field using the Spacebar to match the ISDN call 

type specified by the ISP.

5 If 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 

 for details on how to configure the unit as an IP router.

6 If 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 

 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.

7 To 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.
