    Point-to-Point Protocol (PPP) Introduction Point-To-Point Protocol is designed for simple links which transport packets between two peers. These links provide full- duplex simultaneous bi-directional operation, and are assumed to deliver packets in order. PPP is intended to provide a common solution for easy connection for a wide variety of hosts, bridges and routes.

    PPP HDLC framing is described in RFC1662. PPP over ISDN is described in RFC1618. Related command: ATB40 - Async to Sync PPP conversion. Authentication conversion After a link is established, it is necessary to authenticate the peer for security reasons. There are two popular authentication methods. One is Password Authentication Protocol (PAP) and the other is Challenge Handshake Authentication Protocol (CHAP).

    Bandwidth On Demand (BOD) The function of bandwidth on demand (BOD) will monitor the traffic on ISDN links while Multilink PPP. If there is light traffic on the link, one of the channels will be dropped automatically. On the other hand, if only one B channel is used and data traffic is high enough, BOD will establish the second B channel to increase the bandwidth of the data link.

When you are making a V.120 call, make sure that the communication supports out-of-band signaling. If it does not support out-of-band signaling, you will need to set your TA128 to 56K mode using the AT&E1 command (AT&E0 to set it back to 64k mode.)
