5.2Leased Line Connection

The Leased Line Modem Connection feature allows you to connect the serial port WAN Port 1 to a Leased Line Modem (Async). The Connection Type of WAN port 1 must be selected as [Leased] in Menu 2.1 - Async WAN Port Setup.

Note on PPP Echo Request/Reply

In a Leased Line Connection, a [PPP Echo Request] packet is sent periodically to every link (WAN Port). This is to verify if the link is up. When your Prestige receives a [PPP Echo Request] packet, it will send another [PPP Echo Reply] packet back to the sender through the same link. When [PPP Echo Reply] packets are not received for several times, your Prestige will drop the link.

Note on Backup Function for Leased Line

You can also enable a Backup function for a Leased Line connection. When all the links in a Leased Line Connection drop, your Prestige will pick up any available [Switch] WAN port to place a phone call to establish a Backup connection. When any link (WAN port) in the Leased Line Connection becomes available again, your Prestige will drop the backup connection. The Backup function is usually enabled in a Leased Line Connection for LAN-to-LAN applications.
