16. Enter the ISDN telephone number of your ISP. If required, include the area code and any additional digits needed to get an outside line such as 9.

    NOTES: Some ISPs require you to dial two telephone numbers to place a Multilink PPP call. Use the ampersand (&) character to dial two telephone numbers. For example, 908 555 1212 & 908 555 1213. You must have Chameleon NFS version 4.6.3 or later to use the ampersand (&) character.

    If you experience timeouts, increase the value in the Timeout If Not Connected field.
