 VoIP gateway IP400 version 5.01

One specific application of the ISDN WAN interface is to dial-in to the gateway for
maintenance purposes. This enables remote maintenance of the gateway, without
necessarily having access to the local IP network, as illustrated by Fig. 8 on
page 30.

Fig. 8 Remote maintenance access via ISDN

4.2.1 General considerations on the configuration of the PPP 

connections

Opening a connection

The gateways do not usually establish any connections automatically, when using
dial-up lines. In these cases a PPoE connection is treated as a dial-up line. PPP
connections are thus only established, if an incoming data call is received for a
configured PPP interface, or if the connection is established explicitly via the 

IP

Interfaces

 area of the administration user interface. As a result, full control is

maintained over cost-generating data connections and, in particular, events in the
local network cannot cause any unwanted connection set-ups (no 

dial on

demand

).

Caution

In some cases though, it may be wanted to keep a dial-up line permanently
open. This is achieved by means of the “Automatic dial after boot” setting. It
results in the corresponding PPP connection being established and kept per-
manently open, immediately after starting the gateway. Use this setting with
appropriate caution.
