Establishing a Modem (PPP) Connection with the P330
Overview
Point-to-Point Protocol (PPP) provides a Layer 2 method for transporting multi-
protocol datagrams over modem links.
Connecting a Modem to the Console Port
A PPP connection with a modem can be established only after the Avaya P330 is
configured with an IP address and net-mask, and the PPP parameters used in the
Avaya P330 are compatible with the modem’s PPP parameters.
