To establish a connection to a remote site via the modem connected to the serial interface, a corresponding entry is required in the list of Remote sites (ISDN/serial). The Remote sites (ISDN/serial) list contains the following information:
- Name: Name of the remote site
- Telephone number: Telephone number that reaches the remote site. The field can be left empty if calls are to be received only.
- Short hold time: This time defines how long a connection is kept active even if no more data is being transferred. If a zero is entered, the connection will not be interrupted automatically. A hold time of "9999" means that the connection is permanently held open. If it is interrupted, then the connection will be actively opened up again. This behavior is known as keep alive.
- 2nd Short hold time: Will be ignored.
- Layer name: The layer 'V.24_DEF' is selected for the connection over the
serial WAN interface. The layer is preset and does not need further configuration.
The layer 'V.24_DEF' uses the following settings:
- Encapsulation: Transparent
- Layer-3: APPP (asynchronous PPP)
- Layer-2: Transparent
- Options: None
- Layer-1: SERIAL (shows that the serial interface is being used for connections via the layer 'V.24_DEF')
The Remote sites list with the peers for the modem at the serial interface can be found under the following paths:

Console:
Once an entry in the remote sites list has been generated for the WAN interface, this remote site can be used just like any other for routing and WAN connections.
