497Networking Configuration GuideChapter 69Dial Up overviewThe dial-out interfaces on the BCM offer three key services:• Remote Access allows users at a client station to connect to the BCM across a phone lineusing Point to Point Protocol (PPP). This allows a person working from home or from aremote location to connect to the BCM LAN through a modem and a phone line.• Automatic Dial-Out automatically establish a PPP connection to a remote location through aphone line. Automatic Dial-out can be used for services such as SNMP Trap delivery service,Log download, Backup download, CDR records push, Software Updates pulls and the KeyCodes file upload.• WAN Failover is used in conjunction with the Integrated Router. The Integrated Routermonitors the status of the primary WAN link. When the primary WAN link is detected to havefailed, the Integrated Router will route the traffic to the WAN Failover dial-up interface. Whenthe WAN link recovers the dialled failover WAN connection is terminated and the IP traffic isthen routed over the primary WAN link.The primary WAN link is located on the integrated router and the dialup links are located on theCSC card.Refer to the following information on Remote Access, Automatic Dial-Out, and WAN failoverservices:• “Remote Access Service” on page 498• “Automatic Data Dial-Out Service” on page 499• To configure Dial-In:“Modem Dial-In Parameters panel” on page 514“ISDN Dial-In Parameters panel” on page 518• To configure Dial-Out:“Dial-out Interfaces panel” on page 501• To configure WAN failover“WAN failover” on page 513
