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

PPP provides 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
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.

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.
