Nailed-Up Connection (PPP)
A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand.
The Prestige does two things when you specify a nailed-up connection. The first is that idle timeout is
disabled. The second is that the Prestige will try to bring up the connection when turned on and whenever
the connection is down. A nailed-up connection can be very expensive for obvious reasons.
Do not specify a nailed-up connection unless your telephone company offers flat-rate service or you need a
constant connection and the cost is of no concern
