Chapter 7. Protocol Options

Point-to-Point (PPP) Async-to-Sync

PPPprovides a standard method for transporting multi-protocol datagrams over point-to-point links. The ADTRAN PPP async-sync protocol allows the ISU 128 and a PC or Macintosh® running PPP software, to communicate with a PPP-compatible bridge or router. The PPP async-sync protocol complies with Internet Engineering Task Force (IETF) RFC 1662. The menu path to se- lect PPP is shown in Figure 7-7.

The asynchronous control character map (ACCM) option is scanned during the negotiation. When the ACCM option is seen in a configure ACK link con- trol packet, it is adopted by the ISU 128. In addition, when the ACCM option is not seen in the configure-request packet from the network, the ISU 128 adds it to the packet.

PPP Menu Tree

Point-to-Point Protocol (PPP)

The ISU 128 is configured for PPP from the protocol options of the configura- tion menu by selecting 1=PPP or by setting S-register S27 to a value of 0. Fig- ure 7-6 illustrates the menu path for setting PPP, Multilink PPP, and PPP w/ Comp.

Multilink Point-to-Point Protocol (MP)

Multilink PPP is an extension of point-to-point protocol and is a method for splitting and recombining data packets across multiple logical data links.
