MP
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.
PPP
Incoming PPP connections. PPP sessions are single-channel 
connections to any remote device running PPP software.
COMB
Calls that use Combinet encapsulation and meet all other Answer 
profile criteria. Combinet requires authentication by password and 
MAC address. 
FR
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). 
X25/PAD
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.
X25/T3POS
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).
EU-RAW 
EU-UI
For a description of EU-UI and EU-RAW, see “EU-UI and EU-RAW” 
on page 4-2.
V.120
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.
X.75
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.
