MAX 6000/3000 Network Configuration Guide
Configuring Individual WAN Connections
Description
MP connections, which use RFC 1990 encapsulation. MP enables the
unit to interact with MP-compliant equipment from other vendors to
use multiple channels for a call. Both connection sides must support
MP.
Incoming PPP connections. PPP sessions are single-channel
connections to any remote device running PPP software.
Calls that use Combinet encapsulation and meet all other Answer
profile criteria. Combinet requires authentication by password and
MAC address.
Frame Relay calls. A Frame Relay network provides high throughput
by handing monitoring functions to higher-level protocols. Frame
Relay is a very efficient standard, with a bandwidth of up to 2 Mbps. It
is ideal for situations in which periods of very high traffic are
interspersed with idle periods. Frame Relay is protocol independent,
and performs routing over Virtual Circuits (VCs).
X.25/Packet Assembler/Disassembler calls (X.25/PAD). In an
X.25/PAD configuration, PAD-generated packets are encapsulated in
the X.25 protocol. The PAD assembles data from terminals into
packets for transmission to an X.25 network, and disassembles
incoming packets from the network into a separate data stream for
each terminal. In addition to this multiplexing function, the PAD
provides a nearly error-free connection.
X.25/T3POS calls. T3POS is a character-oriented, frame-formatted
protocol designed for Point-of-Service (POS) transactions using an
X.25 packet switched network. The T3POS protocol involves three
parties: The T3POS/DTE, the T3POS/PAD and the T3POS/Host. The
purpose of the protocol is to enable reliable and efficient data
transactions between a host (usually a transaction server) and a DTE
(usually a client).

on page 4-2.
Calls using V.120 encapsulation. V.120 is a standard for encapsulating
asynchronous data communication into synchronous ISDN data.
Using standard, asynchronous-only COM ports and a V.120 Terminal
Adapter (TA), two computers can communicate over an ISDN
connection.
Calls that use X.75 encapsulation. X.75 is the International
Telecommunication Union–Telecommunication Standardization
Sector (ITU-T) standard for connecting packet-switched networks.
Packet switching is a mode of data transfer in which packets are
transmitted from a specific source to a specific destination over any
available circuit. Packets can take different paths and might not arrive
in the order in which they were sent.
