Profile Configurations
Some common configurations are preset in the Express XRT soft-
ware as profiles. Most Internet service providers supporting
ISDN also support PPP protocol. If connecting to an Internet ser-
vice provider using one B-channel, select
Factory: PPP 64k (Inter-
net), which sets the protocol to PPP. If arrangements have been
made with the Internet service provider to use two B-channels, se-
lect
Factory: Multilink PPP 128k (Internet) , which uses multilink
PPP protocol.
Loading a factory profile has no effect on any ISDN Phone Num-
ber(s) or Switch Type settings already configured. The settings
that are altered when applying a profile are shown as follows:
Factory: PPP 64k (Internet)
Factory: Multilink PPP 128k (Internet)
