PPP ISDN Manual Call Quick Connections
The PPP router should be configured with a remote site profile entry for each router
that will be called. A manual direct dial connection may be performed to establish an initial
connection to a remote site router. Once the connection is established and working
properly, the remote site configuration for that router should be entered into the router.
The remote site profile enables ISDN calls to be placed automatically each time the router
starts up (Auto-Call) or automatically depending upon the time of day activation schedule or
upon receiving IP frames from the local LAN destined for the IP network connected to that
particular PPP router.
